SAFETY

INFORMATION

8 Before mounting or operating the out- board motor, read this entire manual. Reading it should give you an under- standing of the motor and its operation. 8 Before operating the boat, read any

owners or operators manuals supplied with it and all labels. Be sure you under- stand each item before operating. 8 Do not overpower the boat with this

outboard motor. Overpowering the boat could result in loss of control. The rated power of the outboard should be equal to or less than the rated horse- power capacity of the boat. If the rated horsepower capacity of the boat is unknown, consult the dealer or boat manufacturer. 8 Do not modify the outboard. Modifica-

tions could make the motor unfit or unsafe to use. 8 Never operate after drinking alcohol or

taking drugs. About 50% of all boating fatalities involve intoxication. 8 Have an approved personal flotation

device (PFD) on board for every occu- pant. It is a good idea to wear a PFD whenever boating. At a minimum, chil- dren and non-swimmers should always wear PFDs, and everyone should wear PFDs when there are potentially haz- ardous boating conditions. 8 Gasoline is highly flammable, and its

vapors are flammable and explosive. Handle and store gasoline carefully. Make sure there are no gas fumes or leaking fuel before starting the engine.

8 This product emits exhaust gases which contain carbon monoxide, a colorless, odorless gas which may cause brain damage or death when inhaled. Symp- toms include nausea, dizziness, and drowsiness. Keep cockpit and cabin areas well ventilated. Avoid blocking exhaust outlets. 8 Check throttle, shift, and steering for

proper operation before starting the engine. 8 Attach the engine stop switch lanyard

to a secure place on your clothing, or your arm or leg while operating. If you accidentally leave the helm, the lanyard will pull from the switch, stopping the engine. 8 Know the marine laws and regulations

where you will be boating - and obey them. Refer to RULES OF THE ROAD section for basic boating rules. 8 Stay informed about the weather.

Check weather forecasts before boating. Avoid boating in hazardous weather. 8 Tell someone where you are going:

leave a Float Plan with a responsible person. Be sure to cancel the Float Plan when you return. 8 Use common sense and good judgment

when boating. Know your abilities, and be sure you understand how your boat handles under the different boating conditions you may encounter. Operate within your limits, and the limits of your boat. Always operate at safe speeds, and keep a careful watch for obstacles and other traffic. 8 Always watch carefully for swimmers

during the engine operation. 8 Stay away from swimming areas.

BASIC BOATING RULES (Rules of the road)

Just as there are rules which apply when you are driving on streets and high ways, there are waterway rules which apply when you are driving your boat. These rules are used internationally, and are also enforced by the United States Coast Guard and local agencies. You should be aware of these rules, and follow them whenever you encounter another vessel on the water.

Several sets of rules prevail according to geographic location, but are all basically the same as the International Rules of the Road. The rules presented here in your Owners Manual are condensed, and have been provided for your convenience only. Consult your local U.S. Coast Guard Auxil- iary or Department of Motor Vehicles for a complete set of rules governing the waters in which you will be using your boat.

STEERING AND SAILING RULES AND SOUND SIGNALS

Whenever two vessels on the water meet one another, one vessel has the right-of- way; it is called the stand-on vessel. The vessel which does not have the right-of-way is called the give-way or burdened ves- sel. These rules determine which vessel has the right-of-way, and what each vessel should do.

Stand-on Vessel The vessel with the right-of-way has the duty to continue its course and speed, except to avoid an immediate collision. When you maintain your direction and speed, the other vessel will be able to determine how best to avoid you.

Give-way Vessel The vessel which does not have the right- of-way has the duty to take positive and timely action to stay out of the way of the Stand-On vessel. Normally, you should not cross in front of the vessel with the right-of- way. You should slow down or change directions briefly and pass behind the other vessel. You should always move in such a way that the operator of the other vessel can see what you are doing.

The general prudential rule This rule is called Rule 2 in the Inter- national Rules and says,

In obeying and construing these rules due regard shall be had to all dangers of navigation and collision, and to any spe- cial circumstances, which may render a departure from the above rules neces- sary in order to avoid immediate dan- ger.

In other words, follow the standard rules except when a collision will occur unless both vessels try to avoid each other. If that is the case, both vessels become Give- Way vessels.

Page 14

1-7

RULES WHEN ENCOUNTERING VESSELS There are three main situations which you may encounter with other vessels which could lead to a collision unless the Steering Rules are followed: Meeting

(you are approaching another vessel head-on)

Crossing (you are travelling across the other ves- sels path)

Overtaking (you are passing or being passed by another vessel)

In the following illustration, your boat is in the center. You should give the right-of-way to any vessels shown in white area (you are the Give-Way vessel). Any vessels in the shaded area must yield to you (they are the Give-Way vessels). Both you and the meet- ing vessel must alter course to avoid each other.

Meeting If you are meeting another power vessel head on, and are close enough to run the risk of collision, neither of you has the right- of-way! Both of you should alter course to avoid an accident. You should keep the

other vessel on your port (left) side. This rule doesnt apply if both of you will clear one another if you continue on your set course and speed.

Crossing When two power driven vessels are cross- ing each others path close enough to run the risk of collision, the vessel which has the other on the starboard (right) side must keep out of the way of the other. If the other vessel is on your right, you must keep out of its way; you are the Give-Way vessel. If the other vessel is on your port (left) side, remember that you should maintain course and direction, provided the other vessel gives you the right-of-way as it should.

Overtaking If you are passing another vessel, you are the Give-Way vessel. This means that the other vessel is expected to maintain its course and speed. You must stay out of its

way until you are clear of it. Likewise, if another vessel is passing you, you should maintain your speed and direction so that the other vessel can steer itself around you. OTHER SPECIAL SITUATIONS There are three other rules you should be aware of when driving your boat around other vessels.

Narrow Channels and Bends When navigating in narrow channels, you should keep to the right when it is safe and practical to do so. If the operator of a power-driven vessel is preparing to go around a bend that may obstruct the view of other water vessels, the operator should sound a prolonged blast on the whistle (4 to 6 seconds). If another vessel is around the bend, it too should sound the whistle. Even if no reply is heard, however, the vessel should still proceed around the bend with caution. If you navigate such waters with your boat, you will need to carry a portable air horn, available from local marine supply stores.

Fishing Vessel Right-of-way All vessels which are fishing with nets, lines or trawls are considered to befishing ves- sels under the International Rules. Vessels with trolling lines are not considered fishing vessels. Fishing vessels have the right-of- way regardless of position. Fishing vessels cannot, however, impede the passage of other vessels in narrow channels.

Sailing Vessel Right-of-way Sailing vessels should normally be given the right-of-way. The exceptions to this are: 1. When the sailing vessel is overtaking

the power-driven vessel, the power-dri- ven vessel has the right-of-way.

2. Sailing vessels should keep clear of any fishing vessel.

3. In a narrow channel, a sailing vessel should not hamper the safe passage of a power-driven vessel which can navi- gate only in such a channel.

Reading Buoys and Other Markers The waters of the United states are marked for safe navigation by the lateral system of buoyage. Simply put, buoys and markers have an arrangement of shapes, colors, numbers and lights to show which side of the buoy a boater should pass on when navigating in a particular direction. The markings on these buoys are oriented from the perspective of being entered from sea- ward (the boater is going towards the port). This means that red buoys are passed on the starboard (right) side when proceeding from open water into port, and black buoys are to port (left) side. When navigating out of port, your position with respect to the buoys should be reversed; red buoys should be to port and black buoys to star- board.

Many bodies of water used by boaters are entirely within the boundaries of a particular state. The Uniform State Waterway Marking System has been devised for these waters. This system uses buoys and signs with dis- tinctive shapes and colors to show regulato- ry or advisory information. These markers are white with black letters and orange boarders. They signify speed zones, restricted areas, danger areas, and general information.

Remember, markings may vary by geo- graphic location. Always consult local boat- ing authorities before driving your boat in unfamiliar waters.

GASOLINE

If knocking or pinging occurs, use a differ- ent brand of gasoline or premium unlead- ed fuel.

EMU00027

Gasohol

There are two types of gasohol: gasohol containing ethanol and that containing methanol. Gasohol containing ethanol can be used if ethanol content does not exceed 10% and the fuel meets minimum octane ratings. Gasohol containing methanol is not recommended by Yama- ha because it can cause fuel system dam- age or engine performance problems. EMU19570

ENGINE OIL

Use Yamalube 2-M outboard oil. If Yamalube 2-M is not available, use only another outboard motor manufacturers factory-brand oil with TC-W3 rating.

cC Serious engine damage can result from

the use of lower quality oil, including

some commonly available oil brands with

TC-W3 on their label. To avoid the risk,

use only Yamalube 2-M or, if necessary,

another outboard motor manufacturers

factory-brand TC-W3 oil.

Recommended engine oil: YAMALUBE 2 STROKE OUTBOARD OIL

Recommended gasoline: Regular unleaded gasoline with a minimum octane rating of 86 (Pump Octane Number) = (R+M)/2

BATTERY REQUIREMENT

cC Do not use a battery that does not meet

the specified capacity. If a battery which

does not meet specifications is used, the

electric system could perform poorly or

be overloaded, causing electric system

damage.

For electric start models, choose a battery which meets the following specifications.

EMU01860

Minimum cold cranking amps (CCA/SAE): 380 amps at -18C (-0.4F) Minimum marine cranking amps (MCA/ABYC): 502 amps at 0C (32F) Minimum reserve capacity (RC/SAE):

124 minutes

EMU01395

PROPELLER SELECTION

The performance of your outboard motor will be critically affected by your choice of propeller, as an incorrect choice could adversely affect performance and could also seriously damage the motor. Engine speed depends on the propeller size and boat load. If engine speed is too high or too low for good engine performance, this will have an adverse effect on the engine.

64C-9-18-1 2/18/03 10:16 AM Page 17

Page 20

1-13

Yamaha outboard motors are fitted with propellers chosen to perform well over a range of applications, but there may be uses where a propeller with a different pitch would be more appropriate. For a greater operating load, a smaller-pitch propeller is more suitable as it enables the correct engine speed to be main- tained. Conversely, a larger-pitch pro- peller is more suitable for a smaller oper- ating load.

Yamaha dealers stock a range of pro- pellers, and can advise you and install a propeller on your outboard that is best suited to your application. NOTE:

At full throttle and under a maximum boat load, the engines rpm should be within the upper half of the full throttle operating range, as listed in SPECIFICA- TIONS on page 4-1. Select a propeller which fulfills this requirement. If operating under conditions which allow the engines rpm to rise above the maxi- mum recommended range (such as light boat loads), reduce the throttle setting to maintain the rpm in the proper operating range.

1 Propeller diameter (in inches) 2 Propeller pitch (in inches) 3 Type of propeller (propeller mark)

Engine stop lanyard switch

The lock-plate on the end of the lanyard must be attached to the engine stop switch for the engine to run. The lanyard should be attached to a secure place on the operators clothing, or arm or leg. Should the operator fall overboard or leave the helm, the lanyard will pull out the lock plate, stopping ignition to the engine. This will prevent the boat from running away under power.

w 8 Attach the engine stop switch lanyard

to a secure place on your clothing, your

arm or leg while operating.

8 Do not attach the lanyard to clothing

that could tear loose. Do not route the

lanyard in such a way that it could

become entangled, preventing it from

functioning.

8 Avoid accidentally pulling the lanyard

during normal operation. Loss of

engine power means the loss of most

steering control. Also, without engine

power, the boat could slow rapidly.

This could cause people and objects in

the boat to be thrown forward.

fuel management meter calculates speed, miles traveled, and fuel econo- my by water movement at the stern of the boat. This distance can vary greatly from the actual distance traveled because of water currents, sea swells, and the condition of the water speed sensor (partially plugged or damaged). 8 Individual engines may slightly vary in

their fuel consumption due to manufac- turing variations. These variations can be even greater if the engines are of dif- ferent year models. In addition, varia- tions in propellers, even of the same basic dimensions of the same design, can also cause a slight variation in fuel consumption.

cC Incorrect engine height or obstructions to smooth water flow (such as the design or condition of the boat or acce- ssories such as transom ladders/depth finder transducers) can create airborne water spray while the boat is cruising. Severe engine damage may result if the motor is operated continuously in the presence of airborne water spray.

NOTE: During water testing check the buoyancy of the boat, at rest, with its maximum load. Check that the static water level on the exhaust housing is low enough to prevent water entry into the powerhead, when water rises due to waves when the outboard is not running.

w Improper mounting of the outboard

motor could result in hazardous condi-

tions such as poor handling, loss of con-

trol, or fire hazards. Observe the follow-

ing:

8 The information presented in this sec-

tion is intended as reference only. It is

not possible to provide complete

instructions for every possible

boat/motor combination. Proper

mounting depends in part on experi-

ence and the specific boat/motor com-

bination.

8 Your dealer or other person experi-

enced in proper rigging should mount

the motor. If you are mounting the

motor yourself, you should be trained

by an experienced person. [permanent

mounted type]

8 Your dealer or other person experi-

enced in proper outboard motor

mounting should show you how to

mount your motor. [portable type]

Mount the outboard motor on the center line (keel line) of the boat, and ensure that the boat itself is well balanced. Otherwise, the boat will be hard to steer. For boats without a keel or which are asymmetrical, consult your dealer.

w Overpowering a boat may cause severe

motor with more horsepower than the

the boat. If the boat does not have a

capacity plate, consult the boat manufac-

turer.

EMU01299

Mounting Height

To run your boat at optimum efficiency, the water-resistance (drag) of the boat and outboard motor must be made as lit- tle as possible. The mounting-height of the outboard motor greatly affects the water-resistance. If the mounting-height is too high, cavitation tends to occur, thus reducing the propulsion; and if the pro- peller tips cut the air, the engine speed will rise abnormally and cause the engine to overheat. If the mounting-height is too low, the water-resistance will increase and thereby reduce engine efficiency. Mount the engine so that the anti-cavita- tion plate is in alignment with the bottom of the boat . NOTE:

8 The optimum mounting height of the outboard motor is affected by the boat/motor combination. Test runs at different heights can help determine the optimum mounting height. 8 Refer to the section TRIMMING OUT-

BOARD MOTOR for instructions on setting the trim angle of the outboard.

FILLING FUEL AND ENGINE OIL

FILLING FUEL 1) Remove the fuel tank cap. 2) Fill the fuel tank carefully. 3) Close the cap securely after refueling.

Wipe up any spilled fuel.

Ring Free Fuel Additive

Gasoline is a precise blend of many differ- ent substances, each chosen to give certain characteristics. Gasoline blends have been changing in recent years in response to concerns about pollution and resulting emissions regulations. One of the most obvious changes has been the elimination of lead from most fuels.

As gasoline has changed, the amount of additives such as aromatics and oxy- genates has increased. These additives are important for the engines in passenger cars, but they can have detrimental effects in marine engines, particularly 2 cycle out- boards because of increased deposits in the combustion chamber. When enough deposits collect, piston rings begin sticking. Performance drops and engine wear increases dramatically.

While many additives available may reduce deposits, Yamaha recommends the use of Ring Free Fuel Additive, available from your Yamaha dealer. Ring Free has repeat- edly proven its ability to clean combustion deposits from inside the engine, notably the critical piston-ring-land area, and fuel sys- tem components.

FILLING OIL

This engine uses the oil injection system, which provides superior lubrication by ensuring the proper oil ratio for all operat- ing conditions. No fuel premixing is need- ed (except during break-in). Simply pour gasoline into the fuel tank and oil into the oil tank. Convenient indicator segments indicate the status of the oil supply. For details on reading the indicator segments, see Oil level indicator in this chapter. To fill the engine oil tank, proceed as fol- lows:

Do not add gasoline into the oil tank. Fire

or explosion could result.

Check to be sure you have plenty of fuel for your trip. Make sure there are no fuel leaks or gasoline fumes. Be sure the fuel hose is not being flattened or kinked by objects in the boat, and that there are no sharp objects near it.

Oil

Check to be sure you have plenty of oil for your trip.

Controls

Check throttle, shift, and steering for prop- er operation before starting the engine. The controls should work smoothly, with- out binding or unusual free play. Look for loose or damaged connections. Check operation of the starter and stop switches when the outboard moter is in the water.

Engine

Check the engine and engine mounting. Look for loose or damaged fasteners. Check the propeller for damage.

cC Do not start the engine out of water.

Overheating and serious engine damage

can occur.

OPERATION AFTER A LONG PERIOD

OF STORAGE

When operating the engine after a long period (12 months) of storage, proceed as follows: 1) Use a 50:1 gasoline-oil mixture to

start the engine. 2) Start the engine. Leave it idling.

w 8 Do not touch or remove electrical parts

when starting or during operation.

8 Keep hands, hair, and clothes away

from the flywheel and other rotating

parts while the engine is running.

3) Watch for oil flowing through the oil feed pipes. After any air in the oil lines has been expelled, the oil injec- tion system should supply oil normal- ly. If no oil is flowing after 10 minutes of idling, consult your Yamaha dealer.

cC Be sure to take the above steps when

operating the engine after a long period

of storage. Otherwise engine seizure

could occur.

BREAKING IN ENGINE

Your new engine requires a period of break-in to allow mating surfaces of mov- ing parts to wear in evenly. Correct break- in will help ensure proper performance and longer engine life.

cC 8 Failure to follow the break-in procedure

could result in reduced engine life or

even severe engine damage.

8 Premix fuel must be used during break-

in, in addition to oil in the oil injection

system.

Break-in time: 10 hours

Gasoline to engine oil premix ratio during break-in: 50:1

Run the engine under load (in gear with a propeller installed) as follows. 1) First 10 minutes:

Run the engine at the lowest possi- ble-speed. A fast idle in neutral is best.

2) Next 50 minutes: Do not exceed half throttle (approxi- mately 3,000 r/min). Vary engine speed occasionally. If you have an easy-planing boat, accelerate at full throttle onto plane, then immediately reduce the throttle to 3,000 r/min or less.

3) Second hour: Accelerate at full throttle onto plane, then reduce engine speed to three- quarter throttle (approximately 4,000 r/min). Vary engine speed occasional- ly. Run at full throttle for one minute, then allow about 10 minutes of opera- tion at three-quarter throttle or less to let the engine cool.

4) Third through tenth hours: Avoid operating at full throttle for more than 5 minutes at a time. Let the engine cool between full-throttle runs. Vary engine speed occasionally.

5) After the first 10 hours: Operate the engine normally. Use only straight gasoline in the fuel tank. The oil injection system provides proper lubrication for normal opera- tion.

STARTING ENGINE

w 8 Before starting the engine, make sure

that the boat is tightly moored and that

you can steer clear of any obstructions.

Be sure there are no swimmers in the

water near you.

8When the air vent screw is loosened,

gasoline (petrol) vapor will be released.

Gasoline (petrol) is highly flammable,

and its vapors are flammable and

explosive. Refrain from smoking, and

keep away from open flames and

sparks while loosening the air vent

screw.

8 This product emits exhaust gases

which contain carbon monoxide, a col-

orless, odorless gas which may cause

brain damage or death when inhaled.

Symptoms include nausea, dizziness,

and drowsiness. Keep cockpit and

cabin areas well ventilated. Avoid

blocking exhaust outlets.

1) If there is an air vent screw on the fuel tank cap, loosen it 2 or 3 turns.

2) If there is a fuel joint or a fuel cock on the boat, firmly connect the fuel line to the joint or open the fuel cock.

3) Squeeze the primer bulb with the out- let end up until you feel it become firm.

5) Attach the engine stop switch lanyard to a secure place on your clothing, or your arm or leg. Then, install the lock plate on the other end of the lanyard in the engine stop switch.

w 8 Attach the engine stop switch lanyard

to a secure place on your clothing, your

arm or leg while operating.

8 Do not attach the lanyard to clothing

that could tear loose. Do not route the

lanyard where it could become entan-

gled, preventing it from functioning.

8 Avoid accidentally pulling the lanyard

during normal operation. Loss of

engine power means the loss of most

steering control. Also, without engine

power, the boat could slow rapidly.

This could cause people and objects in

the boat to be thrown forward.

6) Turn the main switch to ON. NOTE:

In case of dual-engine operation, when the main switch is turned on, the buzzer operates for a few seconds and stops automatically. Should either of the dual engines stall, the buzzer operates.

WARMING UP ENGINE

1) Before beginning operation, allow the engine to warm up at idling speed for 3 minutes. (Failure to do this will shorten engine life.)

2) Check for a steady flow of water from the cooling-water pilot hole.

cC A continuous flow of water from the pilot hole shows that the water pump is pumping water through the cooling pas- sages. If water is not flowing out of the pilot hole at all times while the engine is running, do not continue to run the engine. Overheating and serious dam- age could occur. Stop the engine and check to see if the water inlet on the lower casing is blocked. If the problem cannot be found and corrected, consult your Yamaha dealer.

TRIMMING OUTBOARD

MOTOR

The trim angle of the outboard motor helps determine the position of the bow of the boat in the water. The correct trim angle will help improve performance and fuel economy while reducing strain on the engine. The correct trim angle depends upon the combination of boat, engine, and propeller. Correct trim is also affected by variables such as the load in the boat, sea conditions, and running speed.

w Excessive trim for the operating condi-

tions (either trim up or trim down) can

cause boat instability and can make

steering the boat more difficult. This

increases the possibility of an accident. If

the boat begins to feel unstable or is hard

to steer, slow down and/or readjust the

trim angle.

NOTE:

Refer to the section ADJUSTING TRIM ANGLE for instructions on usage.

Power Trim/Tilt Model

8 Be sure all people are clear of the out-

board motor when adjusting the

trim/tilt angle, also be careful not to

pinch any body parts between the drive

unit and clamp bracket.

8 Use caution when trying a trim position

for the first time. Increase speed gradu-

ally and watch for any signs of instabili-

ty or control problems.

8 Use the power trim/tilt switch located

on the bottom engine cowling (if

equipped) only when the boat is at a

complete stop with the engine off.

The outboard motor trim angle can be adjusted operating the power trim/tilt switch 1.

To raise the bow (trim-out), push the switch UP.

To lower the bow (trim-in), push the switch DN.

Make test runs with the trim set to differ- ent angles to find the position that works best for your boat and operating condi- tions. NOTE:

To adjust the trim angle while the boat is moving, use the power trim and tilt switch located on the remote control device or tiller handle, if so equipped.

Trim angle settings and boat handling

When the boat is on plane, a bow-up atti- tude results in less drag, greater stability and efficiency. This is generally when the keel line of the boat is up about 3 to 5 degrees. With the bow up, the boat may have a greater tendency to steer to one side or the other. Compensate for this as you steer. The trim tab can also be adjust- ed to help offset this effect.

1 Optimum angle (level keel line) 2 Bow up 3 Bow down

Bow Up

Too much trim-out puts the bow of the boat too high in the water. Performance and economy are decreased because the hull of the boat is pushing the water and there is more air drag. Excessive trim-out can also cause the propeller to ventilate, which reduces performance further, and the boat may porpoise (hop in the water), which could throw the operator and passengers overboard.

Bow Down

When the bow of the boat is down, it is easier to accelerate from a standing start onto plane. Too much trim-in causes the boat to plow through the water, decreasing fuel economy and making it hard to increase speed. Operating with excessive trim-in at higher speeds also makes the boat unstable. Resistance at the bow is greatly increased, heightening the danger of bow steering and making operation difficult and dangerous.

TILTING UP/DOWN

If the engine will be stopped for some time, or if the boat is moored in shallows, the engine should be tilted up to protect the propeller and casing from damage by collision with obstructions, and also to reduce salt corrosion.

cC Before tilting the motor, follow the proce-

dures under STOPPING ENGINE. Never

tilt the motor while the engine is running.

Severe damage from overheating can

result.

w Be sure all people are clear of the out-

board motor when adjusting the tilt

angle, also be careful not to pinch any

body parts between the drive unit and

engine bracket.

w Leaking fuel is a fire hazard. Disconnect

the fuel line or close the fuel cock if the

engine will be tilted for more than a few

minutes. Otherwise, fuel may leak. (If the

fuel connector is provided on the motor.)

000817

NOTE:

Depending on the type of boat, the out- board motor trim angle may have little effect on the trim of the boat when oper- ating.

TRANSPORTING AND

STORING OUTBOARD MOTOR

w Leaking fuel is a fire hazard. When trans-

porting and storing the outboard motor,

close the air vent screw and fuel cock to

prevent fuel from leaking.

TRAILERING OUTBOARD MOTOR The motor should be trailered and stored in the normal running position. If there is insuf- ficient road clearance in this position, then trailer the motor in the tilt position using a motor support device such as a transom saver bar.

cC Do not use the tilt support lever/knob when trailering the boat. The outboard motor could shake loose from the tilt support and fall. If the motor can not be trailered in the down position, use an additional support device to secure it in the up position.

w 8 Never get under the lower unit while it

is tilted, even if a motor support bar is used. Severe injury could occur if the outboard accidentally falls. 8 USE CARE when transporting fuel

tank, whether in a boat or car. DO NOT fill fuel container to maximum capacity. Gasoline will expand considerably as it warms up and can build up pressure in the fuel container. This can cause fuel leakage and a potential fire haz- ard.

STORING OUTBOARD MOTOR

When storing your Yamaha outboard motor for prolonged periods of time (2 months or longer), several important pro- cedures must be performed to prevent excessive damage. This is especially important for your oil injection-equipped outboard motor due to the lean oil ratios used at idle prior to shutting the engine off for the season. It is advisable to have your outboard motor serviced by an authorized Yamaha dealer prior to stor- age. However, the following procedures can be performed by you, the owner, with a minimum of tools.

Filling Fuel Tank

Fill the fuel tank with fresh fuel and add one ounce of Yamaha fuel conditioner and sta- bilizer (Part No. LUB-FUELC-12-00) to each gallon of fuel.

NOTE: The use of Yamaha Fuel Conditioner and Stabilizer eliminates the need to drain the fuel system. Consult your Yamaha dealer or other qualified mechanic if the fuel system is to be drained instead.

Flushing Cooling System and Fogging

Engine

Cooling system flushing is essential to pre- vent the cooling system from clogging up with salt, sand, or dirt. In addition, fogging of the engine is mandatory to prevent expensive engine damage due to rust. Per- form the flushing and fogging at the same time. 1) Remove the top cowling and silencer

cover. Remove the propeller. 2) Install a flushing attachment to the lower

unit. (Flushing attachment available from your Yamaha dealer).

cC Avoid running the outboard at high rpm while on the flushing attachment or overheating could occur.

w 8 Do not touch or remove electrical

parts when starting or during opera- tion. 8 Keep hands, hair and clothes away

from flywheel and other rotating parts while engine is running.

3) Run the engine at a fast idle for 10~15 minutes.

4) Just prior to turning off the engine, quickly spray Yamaha Stor-Rite Engine Fogging Oil (Part No. LUB-STRRT-12- 00) alternately into each carburetor. When properly done, the engine will smoke excessively and almost stall.

5) Remove the flushing attachment and wipe off any excess water.

6) Install the silencer cover and top cowl- ing. Install the propeller.

Lubrication 1) Remove the spark plugs, and spray a 10

second spray of Yamaha Stor-Rite Engine Fogging Oil into each cylinder. Grease the spark plug threads and rein- stall the spark plugs and torque to prop- er specification. (Refer to the Periodic Cleaning and Inspection section, Cleanning and adjusting spark plug.).

2) Turn the engine over with the stop lan- yard disconnected to work the fogging oil into the piston rings.

3) Fill the oil tanks. This prevents the for- mation of condensation. For models with a remote tank, it may be necessary to manually override the control unit to completely fill the engine main tank. (Refer to the Troubleshooting section, Temporary action in emergency.).

4) Change the lower unit oil. (Refer to the Periodic Cleaning and Inpsection sec- tion, Changing gear oil.). Inspect the oil for the presence of water which indi- cates a leaky seal. Seal replacement should be performed by an authorized Yamaha dealership prior to use.

5) Grease all grease fittings. (Refer to the Periodic Cleaning and Inspection sec- tion, Greasing.)

CLEANING AND ADJUSTING SPARK

PLUG

w When removing or installing a spark plug,

be careful not to damage the insulator. A

damaged insulator could allow external

sparks, which could lead to explosion or

fire.

The spark plug is an important engine component and is easy to inspect. The condition of the spark plug can indicate something about the condition of the engine. For example, if the center elec- trode porcelain is very white, this could indicate an intake air leak or carburetion problem in that cylinder. Do not attempt to diagnose any problems yourself. Instead, take the outboard motor to a Yamaha dealer. You should periodically remove and inspect the spark plug because heat and deposits will cause the spark plug to slowly break down and erode. If electrode erosion becomes excessive, or if carbon and other deposits are excessive, you should replace the spark plug with another of the correct type.

Before fitting the spark plug, measure the electrode gap with a wire thickness gauge; adjust the gap to specification if necessary.

Standard spark plug: Refer to SPECIFICATIONS, page 4-1.

Spark plug gap: Refer to SPECIFICATIONS, page 4-1

64C-9-18-4 2/19/03 9:10 AM Page 11

Page 84

4-11

When fitting the plug, always clean the gasket surface and use a new gasket. Wipe off any dirt from the threads and screw in the spark plug to the correct torque.

NOTE:

If a torque-wrench is not available when you are fitting a spark plug, a good esti- mate of the correct torque is 1/4 to 1/2 a turn past finger-tight. Have the spark plug adjusted to the correct torque as soon as possible with a torque-wrench.

CLEANING FUEL FILTER

w Gasoline (petrol) is highly flammable, and

its vapors are flammable and explosive.

8 If you have any question about properly

doing this procedure, consult your

Yamaha dealer.

8 Do not perform this procedure on a hot

or running engine. Allow the engine to

cool.

8 There will be fuel in the fuel filter. Keep

away from sparks, cigarettes, flames or

other sources of ignition.

8 This procedure will allow some fuel to

spill. Catch fuel in a rag. Wipe up any

spilled fuel immediately.

8 The fuel filter must be reassembled

carefully with O-ring, filter cup, and

hoses in place. Improper assembly can

result in a fuel leak, which could result

in a fire or explosion hazard.

EMU09782

1) Remove the nut holding the fuel filter assembly if equipped.

2) Unscrew the filter cup 1, catching any spilled fuel in a rag.

3) Remove the filter element 2, and wash it in solvent. Allow it to dry. Inspect the filter element and O-ring 3 to make sure they are in good con- dition. Replace them if necessary. If any water is found in the fuel, the Yamaha portable fuel tank or other fuel tanks should be checked and cleaned.

4) Reinstall the filter element in the cup. Make sure the O-ring is in position in the cup. Firmly screw the cup onto the filter housing 4.

INSPECTING IDLING SPEED

w 8 Do not touch or remove electrical parts

when starting or during operation.

8 Keep hands, hair and clothes away

from flywheel and other rotating parts

while engine is running.

cC This procedure must be performed while

the outboard motor is in the water. A

flushing attachment or test tank can also

be used.

A diagnostic tachometer should be used for this procedure. Results may vary depending on whether testing is conduct- ed with the flushing attachment, in a test tank, or with the outboard motor in the water. 1) Start the engine and allow it to warm

up fully in neutral until it is running smoothly. If the outboard motor is mounted on a boat, be sure the boat is tightly moored.

2) Verify whether the idle speed is set to specification. For idle speed specifica- tions, see Specifications in this chapter.

5) Attach the filter assembly to the bracket so that the fuel hoses are attached to the filter assembly.

6) Run the engine and check the filter and lines for leaks.

CHECKING BATTERY (for Electric

start models)

w Battery electrolytic fluid is dangerous; it

contains sulfuric acid and therefore is poi-

sonous and highly caustic.

Always follow these preventive mea-

sures:

8 Avoid bodily contact with electrolytic

fluid as it can cause severe burns or

permanent eye injury.

8Wear protective eye gear when han-

dling or working near batteries.

Antidote (EXTERNAL):

8 SKIN - Flush with water.

8 EYES - Flush with water for 15 minutes

and get immediate medical attention.

Antidote (INTERNAL):

8 Drink large quantities of water or milk

followed by milk of magnesia, beaten

egg, or vegetable oil. Get immediate

medical attention.

Batteries also generate explosive hydro-

gen gas; therefore, you should always fol-

low these preventive measures:

8 Charge batteries in a well-ventilated

area.

8 Keep batteries away from fire, sparks,

or open flames (e.g., welding equip-

ment, lighted cigarettes, etc.).

8 DO NOT SMOKE when charging or han-

dling batteries.

8 KEEP BATTERIES AND ELECTROLYTIC

FLUID OUT OF REACH OF CHILDREN.

cC 8 A poorly maintained battery will quick-

ly deteriorate.

8 Ordinary tap-water contains minerals

harmful to a battery, and should not be

used for topping-up.

1) Check the electrolyte level at least once a month. Fill to the manufactur- ers recommended level when neces- sary. Top up only with distilled water (or pure de-ionized water suitable to use in batteries).

2) Always keep the battery in a good state of charge. Installing a voltmeter will help you monitor your battery. If you will not use the boat for a month or more, remove the battery from the boat and store it in a cool, dark place. Completely recharge the battery before using it.

3) If the battery will be stored for longer than a month, check the specific grav- ity of the fluid at least once a month and recharge the battery when it is low.

TEMPORARY ACTION IN EMERGENCY

EMU01492

IMPACT DAMAGE

w The outboard motor can be seriously

damaged by a collision while operating

or trailering. Damage could make the out-

board motor unsafe to operate.

If the outboard motor hits any object in the water, follow the procedure below. 1) Stop the engine immediately. 2) Inspect the control system and all

components for damage. Also, inspect the boat for damage.

3) Whether damage is found or not, return to the nearest harbor slowly and carefully.

4) Have a Yamaha dealer inspect the outboard motor before operating it again.

EMG65210

POWER TRIM / TILT WILL NOT

OPERATE

If the engine cannot be tilted up or down with the power trim and tilt because of a discharged battery or a failure with the power trim and tilt unit, the engine can be tilted manually.

1 Manual valve screw

EMG65111

1) Loosen the manual valve screw coun- terclockwise until it stops.

2) Put the engine in the desired position, then tighten the manual valve screw clockwise.

STARTER WILL NOT OPERATE If the starter mechanism does not operate (engine cannot be cranked with the starter), the engine can be started with an emer- gency starter rope.

w 8 Use this procedure only in an emer-

gency and only to return to port for repairs. 8 When the emergency starter rope is

used to start the engine, the start-in- gear protection device does not oper- ate. Make sure the transmission is in neutral. Otherwise, the boat could unexpectedly start to move, which could result in an accident. 8 Be sure no one is standing behind you

when pulling the starter rope. It could whip behind you and injure someone. 8 An unguarded rotating flywheel is very

dangerous. Keep loose clothing and other objects away when starting the engine. Use the emergency starter rope only as instructed. Do not touch the flywheel or other moving parts when the engine is running. Do not install the starter mechanism or top cowling after the engine is running. 8 Do not touch the ignition coil, high

voltage wire, spark plug cap or other electrical components when starting of operating the motor. You could be shocked.

64C-9-18-5 3/13/03 10:21 AM Page 7

Page 110

5-7

Procedure 1) Remove the top cowling. 2) Remove the flywheel cover by removing

the bolts. 3) Prepare the engine for starting. See

STARTING ENGINE for procedures. Be sure the engine is in Neutral and that the lanyard is attached to the engine stop switch. The main switch must be on.

NOTE: 8 In this case, choke switch will not oper-

ate. Pull out the choke knob when engine is cold. 8 Without setting the main switch to ON, it

is impossible to start the engine.

4) To start the engine with the emergency starter rope, insert the knotted end of the rope into the notch in the flywheel rotor and wind the rope several turns clockwise. Then, give a strong pull straight out to crank the engine. Repeat if necessary.

w Do not install the top cowling when engine is running.

ENGINE FAILS TO OPERATE If battery voltage is low or in the unlikely event of an ignition system malfunction, the engine speed may become erratic or the engine may stop. In such a case, discon- nect the connection on the yellow cord (emergency circuit) to return to port.

w When the connection is disconnected, the idling and low speeds are slightly higher than normal. Use care when start- ing off or stopping.

LOW OIL LEVEL WARNING

ACTIVATES

If the oil level is allowed to drop too low, the red segment will appear on the oil level indicator, the buzzer will sound, and engine speed will be limited to about 2,000 r/min. If this happens, a reserve amount of oil can be pumped from the remote oil tank 3 to the engine oil tank 2 using the emergency switch 1.

w Be sure to stop the engine before per-

forming this procedure.

cC 8 If the emergency switch is held up too

long, too much oil will be pumped into

the engine tank, overflowing it. Release

the switch when oil reaches the upper

level line on the engine oil tank.

8 Do not use this emergency procedure

unless the oil level warning lamps are

installed and working.

1) Remove the top cowling. 2) Turn the main switch to the ON

position. 3) Lift the emergency switch to pump

reserve oil in remote oil tank into the engine oil tank.

4) After using the emergency switch, turn off the main switch, then turn it back on. This resets the warning sys- tem to normal operation. The yellow segment will continue to be displayed on the oil level indicator.

5) Start the engine and return to the nearest port for more oil.

NOTE:

8 Reserve oil capacity is maximum 1,500 cm3 (1.6 US qt, 1.31 Imp qt). 8 Put the engine in the down position

before operating the emergency switch.

TOP COWLING DOES NOT UNLOCK

If the top cowling stays locked when the release lever is operated, the cable may be damaged or misadjusted. 1) Pull the cowling release lever 1 to

unlock the front lock. 2) Pull the emergency cowling release

wire 2 coming out of the hole on the side of the pilot hole in the bottom cowling to release the port side rear lock.

3) Lift the port side of the top cowling to pull out the emergency cowling release wire 3 from the port side of the bottom cowling.

4) Pull the emergency cowling release wire 3 to release the starboard side rear lock.

cC Be sure the problem with the cowling

lock is repaired before reinstalling the

cowling.

TREATMENT OF SUBMERGED MOTOR If the outboard motor is submerged, imme- diately take it a Yamaha dealer. Otherwise, some corrosion may begin almost immedi- ately. If you cannot immediately take the outboard motor to a Yamaha dealer, follow the procedure below for taking care to mini- mize engine damage. 1) Thoroughly wash away mud, salt, sea-

weed, etc. with fresh water. 2) Remove the spark plugs, and face the

spark plug holes downward to allow any water, mud or contaminants to drain.

3) Drain the fuel from the carburetor. 4) Feed fogging oil or engine oil through

the carburetors and spark plug holes while cranking with the manual starter or emergency starter rope.

5) Take the outboard motor to a Yamaha dealer as soon as possible.

cC Do not attempt to run the motor until it has been completely inspected.

IMPORTANT WARRANTY INFORMATION FOR U.S.A. AND

CANADA

Welcome to the Yamaha Family!

Congratulations on the purchase of your new Yamaha marine power. Yamaha is

committed to exceptional customer satisfaction, and we want your ownership

experience to be a satisfying one. Please read the following warranty information to help

ensure satisfaction with your Yamaha.

Yamaha is ready to stand behind your purchase with strong warranty coverage. To be sure you receive all the benefits of warranty, please take the following steps:

1. Be sure your new Yamaha is registered for warranty. Your boat dealer should do this at the time of sale. Make sure your dealer gives you a copy of the completed Yamaha registration card for your records. If you are unsure whether or not your Yamaha is registered, complete the Warranty Registration card found inside the cover of the Owner's Manual. Mail it to the distributor for the country in which you live (see step 6 for the correct address). If your Yamaha is not properly registered, a warranty repair could be unnecessarily delayed while registration records are checked.

2. Read the Limited Warranty statement which follows these instructions. This warranty applies to Yamaha outboard motors sold in the United States, whether purchased separately or when supplied as original equipment by a boat builder. The terms also apply to original equipment packages sold in Canada, with coverage provided by Yamaha Motor Canada (see ``Warranty Guide'' for Canadian models). This warranty explains the conditions of the warranty, including the obligations that your dealer and you as the owner have under the warranty. For example, your Yamaha outboard must receive a proper pre-delivery inspection (PDI) by the selling dealer. Failure to take this important step could jeopardize warranty coverage!

3. If you need warranty repairs, you must take your Yamaha outboard to an authorized Yamaha outboard dealer. Be aware that not all selling boat dealers are authorized Yamaha dealers. Only authorized dealers have the factory training, special tools, and Yamaha support needed to perform warranty repairs.

4. If you are away from home, or your selling dealer is not an authorized Yamaha dealer, use the following toll-free numbers to find the nearest Yamaha dealer.

United States Dealer Locations: 1-800-692-6242

Canada Dealer Locations: 1-800-267-8577

64C-9-18-6 2/19/03 9:13 AM Page 4

Page 119

5. Your warranty applies specifically to repairs made in the country of purchase. If your U.S.-purchased Yamaha needs warranty service while in Canada, or your Canadian purchased Yamaha needs service while in the United States, Yamaha will assist the local dealer whenever possible. However, some products available in one country may not be sold or serviced in the other.

6. If you need any additional information about your Yamaha or warranty coverage which your dealer cannot provide, please contact us directly.

WARRANTY QUESTIONS AND ANSWERS

Q. What costs are my responsibility during the warranty period? A. The customer`s responsibility includes all costs of normal maintenance services, non-warranty repairs, accident and collision

damages.

Q. What are some examples of ``abnormal strain, neglect, or abuse? A. These terms are general and overlap each other in areas. Specific examples include:

Running the machine out of oil, operating the machine with a broken or damaged part which causes another part to fail, damage or failure due to improper or careless transportation, and/or tie down. If you have any specific questions on operation or maintenance, please contact your Yamaha outboard dealer for advice.

Q. Does the warranty cover incidental costs such as towing or transportation due to a failure? A. No. The warranty is limited to repair of the machine itself.

Q. May I perform any or all of the recommended maintenance shown in the Owners Manual instead of having the dealer do them? A. Yes, if you are a qualified mechanic and follow the procedures specified in the Owners and Service Manuals. We do recommend,

however, that items requiring special tools or equipment be done by a Yamaha outboard dealer.

Q. Will the warranty be void or canceled if I do not operate or maintain my new outboard exactly as specified in the Owners Manual? A. No. The warranty on a new outboard cannot be voided`` or canceled``. However, if a particular failure is caused by operation or

maintenance other than as shown in the Owners Manual, that failure may not be covered under warranty.

Q. What responsibility does a Yamaha outboard dealer have under this warranty? A. Each Yamaha outboard dealer is expected to:

1. Completely set up each outboard he sells prior to delivery. 2. Explain the operation, maintenance, and warranty requirements to your satisfaction at the time of sale, and upon your request

at any later date. In addition, each Yamaha outboard dealer is held responsible for his setup, service and warranty repair work.

Q. Is the warranty transferable to second owners? A. Yes. The remainder of any existing warranty can be transferred upon request. The unit has to be inspected and re-registered by an

authorized Yamaha outboard dealer for the policy to remain effective.

2. Keep a copy of your sales contract or invoice for the purchase of your Yamaha and present it if you need warranty repairs. This document should show the date of purchase, which is important evidence the repairing dealer will need to be sure your Yamaha is covered by warranty.

3. If your Yamaha needs warranty repairs, contact an authorized Yamaha dealer in the country where you are. He will explain how to get warranty service in that country.

4. This Yamaha model may not be sold in some countries. Therefore, in some cases your local dealer may not have all the parts or service information he may need, which may unavoidably delay repairs. If this happens, we thank you for your understanding and assure you we will attempt to resolve the situation as quickly as possible.
