Safety information

Before mounting or operating the outboard motor, read this entire manual. Reading it

should give you an understanding of the motor and its operation.

Before operating the boat, read any own- ers or operators manuals supplied with it and all labels. Be sure you understand each item before operating.

Do not overpower the boat with this out- board 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 horsepower capacity of the boat. If the rated horsepower capacity of the boat is unknown, consult the dealer or boat manufacturer.

Do not modify the outboard. Modifications could make the motor unfit or unsafe to use.

Incorrect propeller selection and incorrect use may not only cause engine damage, but also adversely affect fuel consumption. Consult your dealer for correct use.

Never operate after drinking alcohol or tak- ing drugs. About 50% of all boating fatali- ties involve intoxication.

Have an approved personal flotation de- vice (PFD) on board for every occupant. It is a good idea to wear a PFD whenever boating. At a minimum, children and non- swimmers should always wear PFDs, and everyone should wear PFDs when there are potentially hazardous boating condi- tions.

Gasoline is highly flammable, and its va- pors are flammable and explosive. Handle and store gasoline carefully. Make sure there are no gas fumes or leaking fuel be- fore starting the engine.

This product emits exhaust gases which contain carbon monoxide, a colorless, odorless gas which may cause brain dam- age or death when inhaled. Symptoms in-

clude nausea, dizziness, and drowsiness. Keep cockpit and cabin areas well ventilat- ed. Avoid blocking exhaust outlets.

Check throttle, shift, and steering for prop- er operation before starting the engine.

Attach the engine stop switch lanyard cord to a secure place on your clothing, or your arm or leg while operating. If you acciden- tally leave the helm, the cord will pull from the switch, stopping the engine.

Know the marine laws and regulations where you will be boatingand obey them. For basic boating rules, see Rules of the road on page 4.

Stay informed about the weather. Check weather forecasts before boating. Avoid boating in hazardous weather.

Tell someone where you are going: leave a Float Plan with a responsible person. Be sure to cancel the Float Plan when you re- turn.

Use common sense and good judgment when boating. Know your abilities, and be sure you understand how your boat han- dles 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.

Always watch carefully for swimmers dur- ing the engine operation.

Stay away from swimming areas.

When a swimmer is in the water near you shift into neutral and shut off the engine.

Do not illegally discard empty containers used to replace or replenish oil. For the correct processing of empty containers, consult the dealer where you purchased the oil.

When replacing oils used to lubricate the product (engine or gear oil), be sure to

wipe away any spilt oil. Never pour oil with- out using a funnel or similar device. If nec- essary, verify the necessary replacement procedure with the dealer.

Never illegally discard (dump) the product. Yamaha recommends consulting the deal- er on discarding the product.

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 agen- cies. 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 pro- vided for your convenience only. Consult your local U.S. Coast Guard Auxiliary or De- partment of Motor Vehicles for a complete set of rules governing the waters in which you will be using your boat.

EMU25510

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 vessel. 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 brief- ly and pass behind the other vessel. You should always move in such a way that the

ZMU01948

General information

5

operator of the other vessel can see what you are doing.

The general prudential rule

This rule is called Rule 2 in the International Rules and says, In obeying and construing these rules due regard shall be had to all dangers of naviga- tion and collision, and to any special circum- stances, which may render a departure from the above rules necessary in order to avoid immediate danger. In other words, follow the standard rules ex- cept when a collision will occur unless both vessels try to avoid each other. If that is the case, both vessels become Give-Way ves- sels.

EMU25520

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 ves- sel head-on)

Crossing:

(you are traveling across the oth- er vessels 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 shad- ed area must yield to you (they are the Give- Way vessels). Both you and the meeting 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 ves- sel 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 crossing each others path close enough to run the risk of collision, the vessel which has the oth- er 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 direc- tion, provided the other vessel gives you the right-of-way as it should.

General information

6

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 an- other vessel is passing you, you should maintain your speed and direction so that the other vessel can steer itself around you.

EMU25530

Other special situations

There are three other rules you should be aware of when driving your boat around oth- er 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 wa- ter vessels, the operator should sound a pro- longed 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 pro- ceed 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 be fishing 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-driv- en 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 navigat- ing in a particular direction. The markings on these buoys are oriented from the perspec- tive of being entered from seaward (the boat- er is going towards the port). This means that red buoys are passed on the starboard (right) side when proceeding from open wa- ter into port, and black buoys are to port (left) side. When navigating out of port, your posi- tion with respect to the buoys should be re- versed; red buoys should be to port and black buoys to starboard. 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.

General information

7

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, restrict- ed areas, danger areas, and general infor- mation. Remember, markings may vary by geo- graphic location. Always consult local boat- ing authorities before driving your boat in unfamiliar waters.

Fueling instructions

WARNING

EWM00010

GASOLINE AND ITS VAPORS ARE HIGH- LY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and keep

away from sparks, flames, or other sources of ignition.

Stop engine before refueling.

Refuel in a well-ventilated area. Refuel portable fuel tanks off the boat.

Take care not to spill gasoline. If gaso- line spills, wipe it up immediately with

ZMU01708

General information

9

dry rags.

Do not overfill the fuel tank.

Tighten the filler cap securely after re- fueling.

If you should swallow some gasoline, inhale a lot of gasoline vapor, or get gasoline in your eyes, get immediate medical attention.

If any gasoline spills onto your skin, im- mediately wash with soap and water. Change clothing if gasoline spills on it.

Touch the fuel nozzle to the filler open- ing or funnel to help prevent electro-

static sparks.

CAUTION:

ECM00010

Use only new clean gasoline which has been stored in clean containers and is not contaminated with water or foreign mat-

ter.

EMU25570

Gasoline

If knocking or pinging occurs, use a different brand of gasoline or premium unleaded fuel.

Gasohol

There are two types of gasohol: gasohol con- taining ethanol and that containing metha- nol. Gasohol containing ethanol can be used if ethanol content does not exceed 10% and the fuel meets minimum octane ratings. Yamaha does not recommended gasohol containing methanol because it can cause fuel system damage or engine performance problems.

EMU25660

Engine oil

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

CAUTION:

ECM01290

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.

EMU25690

Battery requirement

CAUTION:

ECM01060

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.

Recommended gasoline: Regular unleaded gasoline with a min- imum octane rating of 86 (Pump Oc- tane Number) = (R+M)/2

Recommended engine oil: YAMALUBE 2 STROKE OUTBOARD OIL

EMU25742

Propeller selection

The performance of your outboard motor will be critically affected by your choice of propel- ler, 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. Yamaha outboard motors are fitted with pro- pellers 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 suit- able as it enables the correct engine speed to be maintained. Conversely, a larger-pitch propeller is more suitable for a smaller oper- ating load. Yamaha dealers stock a range of propellers, and can advise you and install a propeller on your outboard that is best suited to your ap- plication.

NOTE:

Select a propeller which will allow the engine to reach the middle or upper half of the oper- ating range at full throttle with the maximum boat load. If operating conditions such as light boat loads then allow the engine r/min to rise above the maximum recommended range, reduce the throttle setting to maintain

the engine in the proper operating range.

For instructions on propeller removal and in- stallation, see page 52.

EMU25770

Start-in-gear protection

Yamaha outboard motors or Yamaha-ap- proved remote control units are equipped with start-in-gear protection device(s). This feature permits the engine to be started only when it is in neutral. Always select neutral before starting the engine.

To activate the choke system, press in the main switch while the key is turned to the (on) or (start) position. The choke system will then supply the rich fuel mixture required to start the engine. When the key is released, the choke will switch off automatically.

EMU25970

Throttle friction adjuster

A friction device provides adjustable resis- tance to movement of the throttle grip or the remote control lever, and can be set accord- ing to operator preference. To increase resistance, turn the adjuster clockwise. To decrease resistance, turn the

adjuster counterclockwise.

WARNING

EWM00030

Do not overtighten the friction adjuster. If there is too much resistance, it could be difficult to move throttle lever or grip,

which could result in an accident.

When constant speed is desired, tighten the adjuster to maintain the desired throttle set- ting.

EMU25990

Engine stop lanyard switch

The lock plate must be attached to the en- gine 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 un- der power.

WARNING

EWM00120

Attach the engine stop switch lanyard to a secure place on your clothing, or your arm or leg while operating.

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.

Avoid accidentally pulling the lanyard

Installation

CAUTION:

ECM00110

Incorrect engine height or obstructions to smooth water flow (such as the design or condition of the boat, or accessories such as transom ladders or 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 ex- haust housing is low enough to prevent wa- ter entry into the powerhead, when water rises due to waves when the outboard is not

running.

EMU26910

Mounting the outboard motor

WARNING

EWM00820

Overpowering a boat could cause se- vere instability. Do not install an out- board motor with more horsepower than the maximum rating on the capac- ity plate of the boat. If the boat does not have a capacity plate, consult the boat manufacturer.

The information presented in this sec- tion is intended as reference only. It is not possible to provide complete in- structions for every possible boat and motor combination. Proper mounting depends in part on experience and the

specific boat and motor combination.

WARNING

EWM00830

Improper mounting of the outboard mo- tor could result in hazardous conditions such as poor handling, loss of control, or fire hazards. Observe the following:

For permanently mounted models, your dealer or other person experienced in proper rigging should mount the motor. If you are mounting the motor yourself, you should be trained by an experi- enced person.

For portable models, your dealer or oth- er person experienced in proper out- board motor mounting should show

you how to mount your motor.

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.

EMU26930

Mounting height (boat bottom)

To run your boat at optimum efficiency, the water resistance (drag) of the boat and out- board motor must be made as little as possi- ble. The mounting height of the outboard

1. Center line (keel line)

1 ZMU01873

Operation

25

motor greatly affects the water resistance. If the mounting height is too high, cavitation tends to occur, thus reducing the propulsion; and if the propeller tips cut the air, the engine speed will rise abnormally and cause the en- gine to overheat. If the mounting height is too low, the water resistance will increase and thereby reduce engine efficiency. Mount the outboard motor so that the anti-cavitation plate is in alignment with the bottom of the boat.

NOTE:

The optimum mounting height of the out- board motor is affected by the boat/motor combination and the desired use. Test runs at different heights can help deter- mine the optimum mounting height. Con- sult your Yamaha dealer or boat manufacturer for further information on de- termining the proper mounting height.

For instructions on setting the trim angle of

the outboard motor, see page 34.

EMU27020

Breaking in engine

Your new engine requires a period of break- in to allow mating surfaces of moving parts to wear in evenly. Correct break-in will help en- sure proper performance and longer engine

life.

CAUTION:

ECM00140

Failure to follow the break-in procedure could result in reduced engine life or even severe engine damage.

Premix fuel must be used during break- in in addition to oil in the oil injection

system.

Ring Free Fuel Additive

Gasoline is a precise blend of many different substances, each chosen to give certain

characteristics. Gasoline blends have been changing in recent years in response to con- cerns about pollution and resulting emis- sions regulations. One of the most obvious changes has been the elimination of lead from most fuels. As gasoline has changed, the amount of ad- ditives such as aromatics and oxygenates has increased. These additives are impor- tant for the engines in passenger cars, but they can have detrimental effects in marine engines, because of increased deposits in the combustion chamber. When enough de- posits collect, piston rings begin sticking. Performance drops and engine wear in- creases dramatically. While many additives available may reduce deposits, Yamaha recommends the use of

Ring Free Fuel Additive

, available from your Yamaha dealer.

Ring Free Fuel Addi- tive

has repeatedly proven its ability to clean combustion deposits from inside the engine, notably the critical piston-ring-land area, and fuel system components. Follow product la- beling for use instructions.

EMU27292

Filling oil for oil injection models

WARNING

EWM00530

Do not add gasoline into the oil tank. Fire

or explosion could result.

This engine uses the Yamaha oil injection system, which provides superior lubrication by ensuring the proper oil ratio for all operat- ing conditions. No fuel premixing is needed. Simply pour gasoline into the fuel tank and oil into the oil tank. Convenient indicators show the status of the oil supply. For details on how to read the indicators, see page 29. To fill the engine oil tank, proceed as follows:

ZMU03907

Operation

WARNING

EWM00420

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.

When the air vent screw is loosened, gasoline vapor will be released. Gaso- line is highly flammable, and its vapors are flammable and explosive. Refrain from smoking, and keep away from open flames and sparks while loosen- ing the air vent screw.

This product emits exhaust gases which contain carbon monoxide, a col- orless, odorless gas which could cause brain damage or death when inhaled. Symptoms include nausea, dizziness, and drowsiness. Keep cockpit and cab- in 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 pump with the outlet end up until you feel it become firm.

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 in- creases 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.

gle, also be careful not to pinch any body parts between the drive unit and clamp bracket.

Use caution when trying a trim position for the first time. Increase speed gradu- ally and watch for any signs of instabil- ity or control problems. Improper trim angle can cause loss of control.

Use the power tilt switch located on the bottom engine cowling (if equipped) only when the boat is at a complete

stop with the engine off.

Adjust the outboard motor trim angle using the power trim and tilt switch.

To raise the bow (trim-out), press the switch (up).

To lower the bow (trim-in), press the switch (down). Make test runs with the trim set to different angles to find the position that works best for your boat and operating conditions.

NOTE:

To adjust the trim angle while the boat is moving, use the power trim and tilt switch lo- cated on the remote control device or tiller

handle, if equipped.

EMU27911

Adjusting boat trim

When the boat is on plane, a bow-up attitude results in less drag, greater stability and effi- ciency. 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 tenden- cy to steer to one side or the other. Compen- sate for this as you steer. The trim tab can also be adjusted to help offset this effect. When the bow of the boat is down, it is easier to accelerate from a standing start onto plane.

Bow Up

Too much trim-out puts the bow of the boat too high in the water. Performance and econ- omy 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 per- formance further, and the boat may por-

poise (hop in the water), which could throw the operator and passengers overboard.

Bow Down

Too much trim-in causes the boat to plow through the water, decreasing fuel economy and making it hard to increase speed. Oper- ating 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 opera- tion difficult and dangerous.

NOTE:

Depending on the type of boat, the outboard motor trim angle may have little effect on the

trim of the boat when operating.

EMU27933

Tilting up and down

If the engine will be stopped for some time or if the boat is moored in shallows, the out- board motor should be tilted up to protect the

propeller and casing from damage by colli- sion with obstructions, and also to reduce salt corrosion.

WARNING

EWM00220

Be sure all people are clear of the out- board motor when tilting up and down, also be careful not to pinch any body parts between the drive unit and engine

bracket.

WARNING

EWM00250

Leaking fuel is a fire hazard. If there is a fuel joint on the outboard motor, discon- nect the fuel line or close the fuel cock if the engine will be tilted for more than a

few minutes. Otherwise fuel may leak.

CAUTION:

Transporting and storing outboard motor

WARNING

EWM00690

Leaking fuel is a fire hazard. When transporting and storing the outboard motor, close the air vent screw and fuel cock to prevent fuel from leaking.

USE CARE when transporting fuel tank, whether in a boat or car.

DO NOT fill fuel container to maximum capacity. Gasoline will expand consid- erably as it warms up and can build up pressure in the fuel container. This can cause fuel leakage and a potential fire

hazard.

WARNING

EWM00700

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

motor accidentally falls.

CAUTION:

ECM00660

Do not use the tilt support lever or knob when trailering the boat. The outboard motor could shake loose from the tilt sup- port and fall. If the motor cannot be trail- ered in the normal running position, use an additional support device to secure it

in the tilt position.

The outboard motor should be trailered and stored in the normal running position. If there is insufficient road clearance in this position, then trailer the outboard motor in the tilt po- sition using a motor support device such as a transom saver bar. Consult your Yamaha dealer for further details.

EMU30272

Storing outboard motor

When storing your Yamaha outboard motor for prolonged periods of time (2 months or longer), several important procedures must be performed to prevent excessive damage. It is advisable to have your outboard motor serviced by an authorized Yamaha dealer prior to storage. However, you, the owner, with a minimum of tools, can perform the fol- lowing procedures.

CAUTION:

ECM01411

Do not place the outboard motor on its side before the cooling water has drained from it completely, otherwise water may enter the cylinder through the exhaust port and cause engine trou- ble.

Store the outboard motor in a dry, well-

ventilated place, not in direct sunlight.

EMU28301

Procedure

EMU28380

Flushing with the flushing attachment

1. Wash the outboard motor body using fresh water. For further information, see page 44.

2. Fill the fuel tank with fresh fuel and add one ounce of Yamaha Fuel Conditioner and Stabilizer (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.

3. Remove the top cowling and silencer cover/cap. Remove the propeller.

4. Install the flushing attachment over the

cooling water inlet.

CAUTION:

ECM00300

Do not run the engine without supplying it with cooling water. Either the engine water pump will be damaged or the en- gine will be damaged from overheating. Before starting the engine, be sure to supply water to the cooling water passag-

es.

CAUTION:

ECM00310

Avoid running the outboard motor at high speed while on the flushing attachment,

otherwise overheating could occur.

5. Cooling system flushing is essential to prevent the cooling system from clog- ging up with salt, sand, or dirt. In addi- tion, fogging/lubricating of the engine is mandatory to prevent excessive engine damage due to rust. Perform the flush- ing and fogging at the same time.

WARNING

EWM00090

Do not touch or remove electrical parts when starting or during operation.

Keep hands, hair, and clothes away from the flywheel and other rotating

parts while the engine is running.

6. Run the engine at a fast idle for 1015 minutes in neutral position while supply- ing fresh water.

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

8. Remove the flushing attachment and wipe off any excess water.

9. Install the silencer cover/cap and top cowling. Install the propeller.

NOTE:

A flushing attachment is available from your

Yamaha dealer.

EMU28410

Lubrication (oil injection models)

1. Grease the spark plug threads and in- stall the spark plug(s) and torque to proper specification. For information on spark plug installation, see page 48.

2. Fill the oil tanks. This prevents the for- mation of condensation. For models with a remote oil tank, it may be necessary to manually override the control unit to completely fill the engine oil tank.

3. Change the gear oil. For instructions, see page 54. Inspect the oil for the pres- ence of water which indicates a leaky seal. Seal replacement should be per- formed by an authorized Yamaha dealer prior to use.

4. Grease all grease fittings. For further de- tails, see page 48.

Battery care

WARNING

EWM00330

Battery electrolytic fluid is dangerous; it contains sulfuric acid and therefore is poisonous and highly caustic. Always follow these preventive mea- sures:

Avoid bodily contact with electrolytic fluid as it can cause severe burns or permanent eye injury.

Wear protective eye gear when han- dling or working near batteries.

Antidote (EXTERNAL):

SKIN - Flush with water.

EYES - Flush with water for 15 minutes and get immediate medical attention.

Antidote (INTERNAL):

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 follow these preventive measures:

Charge batteries in a well-ventilated ar- ea.

Keep batteries away from fire, sparks, or open flames (for example: welding

equipment, lighted cigarettes, and so on.)

DO NOT SMOKE when charging or han- dling batteries.

KEEP BATTERIES AND ELECTROLYTIC

FLUID OUT OF REACH OF CHILDREN.

Batteries vary among manufacturers. There- fore the following procedures may not al- ways apply. Consult your battery manufacturers instructions. Procedure 1. Disconnect and remove the battery from

the boat. Always disconnect the black negative cable first to prevent the risk of shorting.

2. Clean the battery casing and terminals. Fill each cell to the upper level with dis- tilled water.

3. Store the battery on a level surface in a cool, dry, well-ventilated place out of di- rect sunlight.

4. Once a month, check the specific gravity of the electrolyte and recharge as re- quired to prolong battery life.

2. Screw the garden hose connector onto a garden hose which is connected to a fresh water supply.

3. With the engine off, turn on the water tap and let the water flush through the cool- ing passages for about 15 minutes. Turn off the water and disconnect the garden hose.

4. When flushing is complete, reinstall the garden hose connector on the fitting on the bottom cowling. Tighten the connec- tor securely.

CAUTION:

ECM00540

Do not leave the garden hose connector loose on the bottom cowling fitting or let the hose hang free during normal opera- tion. Water will leak out of the connector

instead of cooling the engine, which can cause serious overheating. Be sure the connector is tightened securely on the fit-

ting after flushing the engine.

NOTE:

When flushing the engine with the boat in the water, tilting up the outboard motor un- til it is completely out of the water will achieve better results.

ple, if the center electrode 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 re- move 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 re- place the spark plug with another of the cor- rect type.

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

When fitting the plug, always clean the gas- ket 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 estimate of the correct torque is 1/4 to 1/2 a turn past fin- ger-tight. Have the spark plug adjusted to the correct torque as soon as possible with a

torque-wrench.

Checking battery (for electric start models)

WARNING

EWM00330

Battery electrolytic fluid is dangerous; it contains sulfuric acid and therefore is poisonous and highly caustic. Always follow these preventive mea- sures:

Avoid bodily contact with electrolytic fluid as it can cause severe burns or permanent eye injury.

Wear protective eye gear when han- dling or working near batteries.

Antidote (EXTERNAL):

SKIN - Flush with water.

EYES - Flush with water for 15 minutes and get immediate medical attention.

Antidote (INTERNAL):

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 follow these preventive measures:

Charge batteries in a well-ventilated ar- ea.

Keep batteries away from fire, sparks, or open flames (for example: welding equipment, lighted cigarettes, and so on.)

DO NOT SMOKE when charging or han- dling batteries.

KEEP BATTERIES AND ELECTROLYTIC

FLUID OUT OF REACH OF CHILDREN.

CAUTION:

ECM00360

A poorly maintained battery will quickly deteriorate.

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 manufacturers rec- ommended level when necessary. Top up only with distilled water (or pure de- ionized water suitable to use in batter- ies).

2. Always keep the battery in a good state

Temporary action in emergency

EMU29440

Impact damage

WARNING

EWM00870

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 an object in the wa- ter, follow the procedure below.

1. Stop the engine immediately. 2. Inspect the control system and all com-

ponents for damage. Also inspect the boat for damage.

3. Whether damage is found or not, return to the nearest harbor slowly and careful- ly.

4. Have a Yamaha dealer inspect the out- board motor before operating it again.

EMU29462

Replacing fuse

If the fuse has blown on an electric start model, open the fuse holder and replace the fuse with a new one of the proper amperage.

WARNING

EWM00630

Be sure to use the specified fuse. An in- correct fuse or a piece of wire could allow excessive current flow. This could cause

electric system damage and a fire hazard.

Trouble Recovery

63

NOTE:

Consult your Yamaha dealer if the new fuse

immediately blows again.

EMU29522

Power trim and tilt / power tilt will not operate

If the engine cannot be tilted up or down with the power trim and tilt / the power tilt because of a discharged battery or a failure with the power trim and tilt unit / the power tilt unit, the engine can be tilted manually. 1. Loosen the manual valve screw by turn-

ing it counterclockwise until it stops.

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

turning it clockwise.

EMU29531

Starter will not operate

If the starter mechanism does not operate (the engine cannot be cranked with the start- er), the engine can be started with an emer- gency starter rope.

WARNING

EWM01020

Use this procedure only in an emergen- cy and only to return to port for repairs.

When the emergency starter rope is used to start the engine, the start-in- gear protection device does not oper- ate. Make sure the remote control lever is in neutral. Otherwise the boat could unexpectedly start to move, which could result in an accident.

Attach the engine stop switch lanyard to a secure place on your clothing, or your arm or leg while operating.

Do not attach the lanyard to clothing that could tear loose. Do not route the cord where it could become entangled, preventing it from functioning.

Avoid accidentally pulling the lanyard during normal operation. Loss of en- gine 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.

Be sure no one is standing behind you when pulling the starter rope. It could whip behind you and injure someone.

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 fly- wheel or other moving parts when the
