Safety information EMU33623
Outboard motor safety Observe these precautions at all times. EMU36502
Propeller People can be injured or killed if they come in contact with the propeller. The propeller can keep moving even when the motor is in neutral, and sharp edges of the propeller can cut even when stationary. Stop the engine when a person is in the
water near you. Keep people out of reach of the propeller,
even when the engine is off. EMU33631
Rotating parts Hands, feet, hair, jewelry, clothing, PFD straps, etc. can become entangled with inter- nal rotating parts of the engine, resulting in serious injury or death. Keep the top cowling in place whenever pos- sible. Do not remove or replace the cowling with the engine running. Only operate the engine with the cowling re- moved according to the specific instructions in the manual. Keep hands, feet, hair, jewel- ry, clothing, PFD straps, etc. away from any exposed moving parts. EMU33641
Hot parts During and after operation, engine parts are hot enough to cause burns. Avoid touching any parts under the top cowling until the en- gine has cooled. EMU33651
Electric shock Do not touch any electrical parts while start- ing or operating the engine. They can cause shock or electrocution. EMU33661
Power trim and tilt Body parts can be crushed between the mo-
tor and the clamp bracket when the motor is trimmed or tilted. Keep body parts out of this area at all times. Be sure no one is in this area before operating the power trim and tilt mechanism. The power trim and tilt switches operate even when the main switch is off. Keep peo- ple be away from the switches whenever working around the motor. Never get under the lower unit while it is tilt- ed, even when the tilt support lever is locked. Severe injury could occur if the outboard mo- tor accidentally falls. EMU33672
Engine shut-off cord (lanyard) Attach the engine shut-off cord so that the engine stops if the operator falls overboard or leaves the helm. This prevents the boat from running away under power and leaving people stranded, or running over people or objects. Always attach the engine shut-off cord to a secure place on your clothing or your arm or leg while operating. Do not remove it to leave the helm while the boat is moving. Do not at- tach the cord to clothing that could tear loose, or route the cord where it could be- come entangled, preventing it from function- ing. Do not route the cord where it is likely to be accidentally pulled out. If the cord is pulled during operation, the engine will shut off and you will lose most steering control. The boat could slow rapidly, throwing people and ob- jects forward. EMU33811
Gasoline Gasoline and its vapors are highly flam- mable and explosive. Always, refuel ac- cording to the procedure on page 61 to reduce the risk of fire and explosion.
6C1-9-3D-1E0.book 1

EMU33821
Gasoline exposure and spills Take care not to spill gasoline. If gasoline spills, wipe it up immediately with dry rags. Dispose of rags properly. If any gasoline spills onto your skin, immedi- ately wash with soap and water. Change clothing if gasoline spills on it. If you swallow gasoline, inhale a lot of gaso- line vapor, or get gasoline in your eyes, get immediate medical attention. Never siphon fuel by mouth. EMU33901
Carbon monoxide This product emits exhaust gases which con- tain carbon monoxide, a colorless, 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. EMU33781
Modifications Do not attempt to modify this outboard mo- tor. Modifications to your outboard motor may reduce safety and reliability, and render the outboard unsafe or illegal to use. EMU33741
Boating safety This section includes a few of the many im- portant safety precautions that you should follow when boating. EMU33711
Alcohol and drugs Never operate after drinking alcohol or taking drugs. Intoxication is one of the most com- mon factors contributing to boating fatalities. EMU40281
Personal flotation devices (PFDs) Have an approved PFD on board for every occupant. Yamaha recommends that you must 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 conditions. EMU33732
People in the water Always watch carefully for people in the wa- ter, such as swimmers, skiers, or divers, whenever the engine is running. When someone is in the water near the boat, shift into neutral and stop the engine. Stay away from swimming areas. Swimmers can be hard to see. The propeller can keep moving even when the motor is in neutral. Stop the engine when a person is in the water near you. EMU33752
Passengers Consult your boat manufacturers instruc- tions for details about appropriate passenger locations in your boat and be sure all pas- sengers are positioned properly before ac- celerating and when operating above an idle speed. Standing or sitting in non-designated locations may result in being thrown either overboard or within the boat due to waves, wakes, or sudden changes in speed or direc- tion. Even when people are positioned prop- erly, alert your passengers if you must make any unusual maneuver. Always avoid jump- ing waves or wakes. EMU33762
Overloading Do not overload the boat. Consult the boat capacity plate or boat manufacturer for max- imum weight and number of passengers. Be sure that weight is properly distributed ac- cording to the boat manufacturers instruc- tions. Overloading or incorrect weight distribution can compromise the boats han- dling and lead to an accident, capsizing or swamping.

EMU33773
Avoid collisions Scan constantly for people, objects, and oth- er boats. Be alert for conditions that limit your visibility or block your vision of others.
Operate defensively at safe speeds and keep a safe distance away from people, ob- jects, and other boats. Do not follow directly behind other boats or
waterskiers. Avoid sharp turns or other maneuvers that
make it hard for others to avoid you or un- derstand where you are going.
Avoid areas with submerged objects or shallow water.
Ride within your limits and avoid aggres- sive maneuvers to reduce the risk of loss of control, ejection, and collision.
Take early action to avoid collisions. Re- member, boats do not have brakes, and stopping the engine or reducing throttle can reduce the ability to steer. If you are not sure that you can stop in time before hitting an obstacle, apply throttle and turn in another direction.
EMU33791
Weather Stay informed about the weather. Check weather forecasts before boating. Avoid boating in hazardous weather.
EMU44161
Accident reporting Boat operators are required by law to file a Boating Accident Report with their boating law enforcement agency if their boat is in- volved in any of the following accidents: 1. There is loss of life or probable loss of
life. 2. There is personal injury that requires
medical attention beyond first aid. 3. There is property damage to boats or
other property over a certain amount. 4. There is complete loss of a boat. Contact local law enforcement personnel if a report is necessary. EMU44171
Boat education and training For U.S.A. Operators should take a boating safety course. This may be required in your state. Many of the organizations listed in the next section can provide information about cours- es in your area. You may also want to consider an Internet- based program for basic boater education. The Online Boating Safety Course provided by the BoatU.S. Foundation, is approved by the National Association of State Boating Law Administrators (NASBLA) and recog- nized by the United States Coast Guard. Most, but not all, states accept this course to meet their minimum requirements. While it cannot replace an in-depth course such as one offered by the U.S. Coast Guard, U.S. Power Squadron, or other organization, this online course does provide a general over- view of the basics in boating safety, require- ments, navigation, and operation. Upon successful completion of the course, the user can download a certificate of comple- tion immediately or, for a small charge, re- quest one by mail. To take this free course,

go to boatus.org. For Canada All operators of pleasure craft must illustrate competency by means of a Pleasure Craft Operators Card with the exception of Per- sonal Water Craft used for rental purposes which require a rental checklist be complet- ed. Pleasure Craft Operators Cards can be obtained following the completion of a com- petency course, with an on-line option. De- tails can be found on Transport Canadas website. www.tc.gc.ca EMU33881
Passenger training Make sure at least one other passenger is trained to operate the boat in the event of an emergency. EMU33891
Boating safety publications Be informed about boating safety. Additional publications and information can be obtained from many boating organizations. EMU33591
Laws and regulations Know the marine laws and regulations where you will be boating- and obey them. Several sets of rules prevail according to geographic location, but all are basically the same as the International Rules of the Road. The rules presented in the following section are con- densed- and have been provided for your convenience only. Contact the U.S. Coast Guard, the National Association of State Boating Law Adminis- trators, or your local Power Squadron for a complete set of rules governing the waters in which you will be using your boat.

Basic boating rules (Rules of the road)
Just as there are rules that apply when you are driving on streets and highways, there are waterway rules that apply when you are driving your boat. These rules are used inter- nationally. (For U.S.A.: and are also en- forced 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. EMU33701
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 that does not have the right-of-way is called the give-way or burdenedvessel. 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 that 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 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 vessels. EMU25522
Rules when encountering vessels There are three main situations that 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.
6C1-9-3D-1E0.book 5
Safety information
6
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.
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. EMU25532
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 that are fishing with nets, lines or
6C1-9-3D-1E0.book 6
Safety information
7
trawls are considered to be fishing vessels under the International Rules. Vessels with trolling lines are not considered fishing ves- sels. Fishing vessels have the right-of-way regardless of position. Fishing vessels can- not, 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-driven 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 that can navigate 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.
This system uses buoys and signs with dis- tinctive shapes and colors to show regulatory 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.

working correctly and you should dis- continue using the outboard. Contact your Yamaha dealer.
The remote control unit must be equipped with a start-in-gear protection device(s). This device prevents the engine from starting un- less it is in neutral. EMU25695
Battery requirements EMU25716
Specifications of Battery Use a fully charged battery that meets the following specifications. The engine cannot be started if battery voltage is too low.
NOTICE ECM01063
Do not use a battery that does not meet the specified capacity. If a battery that does not meet specifications is used, the electric system could perform poor- ly or be overloaded, causing electric system damage.
Do not use a battery which exceeds the maximum CCA rating. If the batteries are used in parallel circuit, use new bat- teries of the same type and make sure that the total battery rating never ex- ceed the maximum CCA rating.
EMU36291
Mounting battery Mount the battery holder securely in a dry, well-ventilated, vibration-free location in the boat. WARNING! Do not put flammable items, or loose heavy or metal objects in
the same compartment as the battery. Fire, explosion or sparks could result. [EWM01821]
EMU36301
Multiple batteries To connect multiple batteries, such as for multiple engine configurations or for an ac- cessory battery, consult your Yamaha dealer about battery selection and correct wiring. EMU34196
Propeller selection Next to selecting an outboard motor, select- ing the right propeller is one of the most im- portant purchasing decisions a boater can make. The type, size, and design of your pro- peller have a direct impact on acceleration, top speed, fuel economy, and even engine life. Yamaha designs and manufactures pro- pellers for every Yamaha outboard motor and every application. Your outboard motor came with a Yamaha propeller selected to perform well over a range of applications, but there may be uses where a different propeller would be more appropriate. Your Yamaha dealer can help you select the right propeller for your boating needs. Select a propeller that will allow the engine to reach the middle or upper half of the operating range at full throttle with the maximum boat- load. Generally, select a larger pitch propel- ler for a smaller operating load and a smaller pitch propeller for a heavier load. If you carry loads that vary widely, select the propeller that lets the engine run in the proper range for your maximum load but remember that you may need to reduce your throttle setting to stay within the recommended engine speed range when carrying lighter loads. To check the propeller, see page 88.

EMU36361
Fuel requirements EMU41332
Gasoline Use a good quality gasoline that meets the minimum octane requirement. If knocking or pinging occurs, use a different brand of gas- oline or premium unleaded fuel. Yamaha recommends that you use alcohol-free gaso- line (see Gasoline with Ethanol) whenever possible. The use of a poor quality gasoline may result in starting and running problems. If you en- counter drivability problems, which you sus- pect could be related to the fuel you are using, we recommend that you switch to a recognized high quality brand of gasoline, such as a gasoline that is advertised as Top Tier Detergent Gasoline. Failure to comply with these recommendations may also result in unscheduled maintenance, fuel system damage, and internal engine damage.
NOTICE ECM01982
Do not use leaded gasoline. Leaded gasoline can seriously damage the en- gine.
Avoid getting water and contaminants in the fuel tank. Contaminated fuel can cause poor performance or engine damage. Use only fresh gasoline that has been stored in clean containers.
Gasoline with Ethanol Two types of gasoline are commonly avail- able in the U.S.A. and Canada for use in au- tomobiles and boats: conventional gasoline
without Ethanol and gasoline with Ethanol, which is typically referred to as E10 gasoline. According to federal regulations, E10 gaso- line may contain up to 10% Ethanol. A high quality gasoline without Ethanol is the preferred fuel for your Yamaha outboard mo- tor. However, if gasoline with Ethanol is the only fuel available in your area, your Yamaha outboard motor is calibrated to run properly on fresh E10 gasoline that meets the mini- mum octane requirement specified for this model.
NOTICE ECM02402
Never use a gasoline for your outboard motor that contains more than 10% Etha- nol, such as E15 which contains 15% Eth- anol or E85 which contains 85% Ethanol, or gasoline containing any amount of Methanol. These fuels can cause starting and running problems, as well as serious fuel system and internal engine damage.
Gasoline containing ethanol has several properties that may cause boat fuel system problems. Ethanol is a strong solvent (cleaning
agent) that can clean gum and varnish de- posits from a boats fuel system, particular- ly in older boats, as well as tanks and pipes used in gasoline distribution. These re- leased deposits contaminate the fuel and can cause problems, such as clogged fuel filters, carburetors, or fuel injectors, which could result in engine damage.
Ethanol may dissolve resins used in the construction of fiberglass fuel tanks. The dissolved resins contaminate the fuel and can cause problems, such as clogged fuel filters, carburetors, or fuel injectors, which could result in engine damage.
Ethanol is hygroscopic (has a strong at-

20
traction to water). Therefore, any water that inadvertently enters the fuel system, including moisture that is absorbed from the air, will mix with the ethanol in the gas- oline. If the amount of water is excessive, the ethanol and water mixture will separate from the gasoline in a layer at the bottom of the fuel tank. This ethanol and water mixture is very corrosive to aluminum fuel tanks and fuel system components.
The usable life span of E10 gasoline may be shorter than the normal length of off- season boat storage, causing starting and running problems related to stale fuel.
For more information on using fuel contain- ing ethanol, visit: http://www.yamaha-mo- tor.com Gasoline Filtration Yamaha outboard motors are equipped with internal fuel filters. However, excessive wa- ter or debris entering your engines fuel sys- tem could prematurely clog the internal filters, causing starting and running prob- lems, fuel system damage, and internal en- gine damage. Therefore, it is recommended that an external 10-micron water-separating fuel filter be installed on your boat and ser- viced frequently. Consult your authorized Yamaha dealer for a 10-micron filter that meets your engines requirements. EMU41342
Gasoline Additives Gasoline blends change to meet automobile emission regulations and economic condi- tions. Additives, added by gasoline distribu- tors, necessary for proper automobile engine operation and durability, may not be suffi- cient for typical boat applications. Intake valve and combustion chamber deposits may accumulate in boat engines more rapid- ly than encountered in automotive use. In ad-
dition, gasoline used for boating will typically age longer between refills than gasoline used in automobiles, resulting in stale and unusable gasoline that may cause starting and running problems, fuel system damage, and internal engine damage. Yamaha recommends the use of two Yama- lube gasoline additives to reduce internal de- posits and extend the storage life of gasoline. Continuous use of Yamalube Ring Free Fuel Additive Plus reduces harmful in- ternal deposits. Yamalube Fuel Stabilizer & Conditioner Plus added to fresh gasoline will help protect the fuel system from varnishing while helping to keep the gasolines octane level from decreasing excessively during storage. Other additives may also be avail- able on the market that may have varying de- grees of effectiveness. Consult your Yamaha dealer concerning what may work best for the locally available gasoline and environ- mental conditions. EMU41351
Anti-fouling paint A clean hull is required to maintain your boats performance. Boats moored in the wa- ter should be protected from marine growth (barnacles, mussels, and marine plants). If approved by regulations for your area, the bottom of the hull can be coated with an anti- fouling paint to inhibit marine growth. Anti-fouling paints specifically formulated for use on aluminum may be applied to the out- board motor. The original Yamaha paint sur- face may be scuffed lightly before applying anti-fouling paint, but do not remove the orig- inal paint. Removal of the original paint will increase the rate of corrosion.

may contain materials, such as copper, graphite, and tin, that can cause corro- sion if applied to aluminum boats and outboard motor components. Never ap- ply these types of paint to your outboard motor because rapid corrosion damage could occur.
Sacrificial anodes are attached to the out- board motor to provide corrosion protection and must never be painted.
NOTICE ECM02421
Painted sacrificial anodes will not provide corrosion protection.
EMU36342
Motor disposal requirements Never illegally discard (dump) the motor. Yamaha recommends consulting the dealer about discarding the motor. EMU36353
Emergency equipment Keep the following items onboard in case there is trouble with the outboard motor. A tool kit with assorted screwdrivers, pli-
ers, wrenches (including metric sizes), and electrical tape.
Waterproof flashlight with extra batteries. An extra engine shut-off cord (lanyard)
with clip. Spare parts, such as an extra set of spark
plugs. Consult your Yamaha dealer for details. EMU25223

Trim tab with anode
WARNING EWM00841
An improperly adjusted trim tab could cause difficult steering. Always test run after the trim tab has been installed or re- placed to be sure steering is correct. Be sure you have tightened the bolt after ad- justing the trim tab.
The trim tab should be adjusted so that the steering control can be turned to either the right or left by applying the same amount of force. If the boat tends to veer to the left (port side), turn the trim tab rear end to the port side A in the figure. If the boat tends to veer to the right (starboard side), turn the trim tab end to the starboard side B in the figure.

Installation EMU26903
Installation The information presented in this section is intended as reference only. It is not possible to provide complete instructions for every possible boat and motor combination. Proper mounting depends in part on experience and the specific boat and motor combination.
WARNING EWM01591
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.
Improper mounting of the outboard mo- tor could result in hazardous condi- tions such as poor handling, loss of control, or fire hazards. For permanent- ly mounted models, your dealer or oth- er person experienced in proper rigging should mount the motor.
EMU33471
Mounting the outboard motor The outboard motor should be mounted so that the boat is well balanced. Otherwise, the boat could be hard to steer. For single-en- gine boats, mount the outboard motor on the centerline (keel line) of the boat.
EMU26935
Mounting height (boat bottom) The mounting height of your outboard motor affects its efficiency and reliability. If it is mounted too high, propeller ventilation may occur, which will reduce propulsion due to excessive propeller slip, and the water in- takes for the cooling system may not get ad- equate water supply, which can cause engine overheating. If the engine is mounted too low, water resistance (drag) will increase, thereby reducing engine efficiency and per- formance. Most commonly, outboard motor should be mounted so that the anti-cavitation plate is in alignment with the bottom of the boat. The optimum mounting height of the outboard motor is affected by the boat/motor combina- tion and the desired use. Test runs at differ- ent heights can help determine the optimum mounting height. Consult your Yamaha deal- er or boat manufacturer for further informa- tion on determining the proper mounting height.

NOTICE ECM01635
Make sure that the idle hole is high enough to prevent water from entering the engine even if the boat is stationary with the maximum load.
Incorrect engine height or obstructions to the smooth flow of water (such as the design or condition of the boat, or ac- cessories, such as transom ladders or depth finder transducers) can create airborne water spray while the boat is cruising. If the outboard motor is oper- ated continuously in the presence of airborne water spray, enough water could enter the engine through the air intake opening in the top cowling to cause severe engine damage. Remove the cause of the airborne water spray.

Operation EMU36382
First-time operation EMU36393
Fill engine oil The engine is shipped from the factory with- out engine oil. If your dealer did not fill the oil, you must fill it before starting the engine. NOTICE: Check that the engine is filled with oil before first-time operation to avoid severe engine damage. [ECM01782]
The engine is shipped with the following tag, which should be removed after engine oil is filled for the first time. For more information on checking the engine oil level, see page 57.
EMU30175
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. NOTICE: Failure to follow the break-in
procedure could result in reduced engine life or even severe engine damage. [ECM00802]
EMU27086
Procedure for 4-stroke models Your new engine requires a period of 10 hours break-in to allow mating surfaces of moving parts to wear in evenly.
TIP: Run the engine in the water, under load (in gear with a propeller installed) as follows. For 10 hours for breaking in engine avoid ex- tended idling, rough water and crowded ar- eas. 1. For the first hour of operation:
Run the engine at varying speeds up to 2000 r/min or approximately half throttle.
2. For the second hour of operation: Increase engine speed as much as nec- essary to put the boat on plane (but avoid full-throttle operation), then back off on the throttle while keeping the boat at a planing speed.
3. Remaining 8 hours: Run the engine at any speed. However, avoid operating at full throttle for more than 5 minutes at a time.
4. After the first 10 hours: Operate the engine normally.

Trimming outboard motor
WARNING EWM00741
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.
The trim angle of the outboard motor helps determine the position of the bow of the boat in the water. Correct trim angle will help im- prove performance and fuel economy while reducing strain on the engine. 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.
EMU27889
Adjusting trim angle (Power trim and tilt)
WARNING EWM00754
Be sure all people are clear of the out- board motor when adjusting the trim angle. Body parts can be crushed be- tween the motor and the clamp bracket when the motor is trimmed or tilted.
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.
If equipped with a power trim and tilt switch located on the bottom cowling, use the switch only when the boat is at a complete stop with the engine off. Do not adjust the trim angle with this switch while the boat is moving.

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. EMU27913
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. 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.
TIP: Depending on the type of boat, the outboard motor trim angle may have little effect on the trim of the boat when operating. EMU27936
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 lower casing from damage by collision with obstructions, and also to re- duce salt corrosion.
WARNING EWM00223
Make sure that no one is near the out- board motor when tilting the outboard motor up or down. Otherwise, body parts could be crushed between the outboard motor and the clamp bracket.
WARNING EWM00251
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.

Transporting and storing outboard motor
WARNING EWM02621
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.
Leaking fuel is a fire hazard. When transporting and storing the outboard motor, disconnect the fuel line from the outboard motor to prevent fuel from leaking.
Never get under the outboard motor while it is tilted. Severe injury could oc- cur if the outboard motor accidentally falls.
Do not use the tilt support lever or knob when trailering the boat. The outboard motor could shake loose from the tilt support and fall. If the outboard motor cannot be trailered in the normal run- ning position, use an additional sup- port device to secure it in the tilt position.
When storing or transporting the outboard motor, make sure to follow the procedure list- ed below. Disconnect the fuel hose from the fuel joint
on the outboard motor. Tighten the fuel tank cap and its air vent
screw. Store the fuel tank in a well-ventilated
place. Store the fuel tank in a place that is stable
and not exposed to shocks.
When the outboard motor is tilted for a pro- longed time for mooring or trailering the boat, make sure to follow the procedure listed be- low. Disconnect the fuel hose from the fuel joint
on the outboard motor. Tighten the fuel tank cap and its air vent
screw. The outboard motor should be transported and stored in the normal running position. If there is insufficient road clearance in this po- sition, then trailer the outboard motor in the tilt position using a motor support device such as a transom saver bar. Consult your Yamaha dealer for further details.
EMU28281
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.
NOTICE ECM01081

the attitude shown when transporting and storing it. If storing or transporting the outboard motor on its side (not up- right), put it on a cushion after draining the engine oil.
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.
EMU28306
Procedure EMU30009
Flushing with the flushing attachment 1. Wash the outboard motor body using
fresh water. NOTICE: Do not spray wa- ter into the air intake. [ECM01841] For fur- ther information, see page 78.
2. Fill the fuel tank with fresh fuel and add one ounce of Yamaha Fuel Conditioner and Stabilizer to each gallon of fuel.
TIP: 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 propeller. 4. Install the flushing attachment over the
cooling water inlet. NOTICE: Do not run the engine without supplying it with cooling water. Either the engine water pump will be damaged or the engine will be damaged from overheating. Before starting the engine, be sure to supply water to the cooling water passages. Avoid running the out- board motor at high speed while on
the flushing attachment, otherwise overheating could occur. [ECM02001]
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! Do not touch or remove electrical parts when starting or dur- ing operation. Keep hands, hair, and clothes away from the flywheel and other rotating parts while the engine is running. [EWM00092]
TIP: When using the flushing attachment, main-
tain adequate water pressure and a steady water flow.
If the overheat alert device is activated, turn the engine off, and consult your Yamaha dealer.
6. Run the engine at a fast idle for a few minutes in neutral position while supply- ing fresh water.

Periodic maintenance
WARNING EWM01872
These procedures require mechanical skills, tools, and supplies. If you do not have the proper skills, tools, or supplies to perform a maintenance procedure, have a Yamaha dealer or other qualified mechanic do the work. The procedures involve disassembling the motor and exposing dangerous parts. To reduce the risk of injury from moving, hot, or electrical parts: Turn off the engine and keep the key(s)
and engine shut-off cord (lanyard) with you when you perform maintenance un- less otherwise specified.
The power trim and tilt switches oper- ate even when the ignition key is off. Keep people away from the switches whenever working around the motor. When the motor is tilted, keep away from the area under it or between it and the clamp bracket. Be sure no one is in this area before operating the power trim and tilt mechanism.
Allow the engine to cool before han- dling hot parts or fluids.
Always completely reassemble the mo- tor before operation.
Maintenance, replacement, or repair of the emission control devices and sys- tems may be performed by any marine engine repair establishment or individual. All warranty repairs, however, including those to the emission control system, must be performed by an authorized Yamaha marine dealership.
A service manual is available for purchase through your Yamaha dealer for owners who have the mechanical skills, tools, and other equipment necessary to perform mainte- nance not covered by this owners manual. EMU28512
Replacement parts If replacement parts are necessary, use only genuine Yamaha parts or parts of equivalent design and quality. Any part of inferior quality may malfunction, and the resulting loss of control could endanger the operator and passengers. Yamaha genuine parts and ac- cessories are available from your Yamaha dealer. EMU35522
Maintenance interval guidelines The service intervals provided in the Mainte- nance Chart were developed based upon typical use that includes operating at varied speeds, with sufficient time for engine warm up and cool-down, a medium to light load, and an average cruising speed near the 3000 to 4000 rpm range. As with any engine, however, if your normal operating conditions are different, you should consider service more often than shown, especially how often you change your engine oil and gear oil. Ex- amples might include extended wide-open- throttle use or long periods of trolling or idling, carrying heavy loads, or frequent starting and stopping or shifting. More fre- quent maintenance will often pay off many times over in increased engine life and great- er owner satisfaction. Consult your Yamaha dealer for additional maintenance recom- mendations.

Cleaning and adjusting spark plug The spark plug is an important engine com- ponent and is easy to inspect. The condition of the spark plug can indicate something about the condition of the engine. For exam- 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. 1. Remove the spark plug caps from the
spark plugs. 2. Remove the spark plug. If electrode ero-
sion becomes excessive, or if carbon and other deposits are excessive, you should replace the spark plug with an- other of the correct type. WARNING! When removing or installing a spark plug, be careful not to damage the in-

sulator. A damaged insulator could allow external sparks, which could lead to explosion or fire. [EWM00562]
3. Be sure to use the specified spark plug, otherwise the engine may not operate properly. Before fitting the spark plug, measure the electrode gap with a wire thickness gauge; replace it if out of spec- ification.
4. When fitting the plug, wipe off any dirt from the threads, and then screw it in to the correct torque.
TIP: If a torque-wrench is not available when you are reinstalling a spark plug, a good estimate of the correct torque is 1/12 turn past finger- tight. When you are installing a new spark plug, a good estimate of the correct torque is 1/2 turn past finger-tight. EMU29045
Inspecting idle speed
WARNING EWM00452
Do not touch or remove electrical parts when starting or during operation.

Water separator-alert indicator blinks while cruising
WARNING EWM01501
Gasoline is highly flammable, and its va- pors are flammable and explosive. Do not perform this procedure on a hot
or running engine. Allow the engine to cool.
There will be fuel in the fuel filter. Keep away from sparks, cigarettes, flames or other sources of ignition.
This procedure will allow some fuel to spill. Catch fuel in a rag. Wipe up any spilled fuel immediately.
The fuel filter must be reassembled carefully with the O-ring, filter cup, and hoses in place. Improper assembly or replacement could result in a fuel leak, which could result in a fire or explosion hazard.
If the water separator-alert indicator on the 6Y8 Multifunction tachometer blinks, perform the following procedure.
F50, T50, F60, T60 1. Stop the engine. 2. Remove the top cowling. 3. Remove the plastic tie.
4. Disconnect the water detection switch coupler. NOTICE: Be careful not to get any water on the water detection switch coupler, otherwise a malfunc- tion could occur. [ECM01951]

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 manually with an emergency starter rope. However, the en- gine cannot be started manually if the battery voltage is low. If the battery is discharged to 9 volts or below, the electric fuel pump will not operate.
WARNING EWM01023
Use this procedure only in an emergen- cy to return to the nearest port for re- pairs.
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 shut-off cord to a se-
cure place on your clothing, or your arm or leg while operating the boat.
Do not attach the cord to clothing that could tear loose. Do not route the cord where it could become entangled, pre- venting it from functioning.
Avoid accidentally pulling the cord dur- ing 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.
Make 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 engine is running. Do not install the starter mechanism or top cowling after the engine is running.
Do not touch the ignition coil, spark plug wire, spark plug cap, or other elec- trical components when starting or op- erating the motor. You could get an electrical shock.

Welcome to the Yamaha Family!
Congratulations on the purchase of your new Yamaha products. Yamaha is commit- ted 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.
This model was manufactured with specifications appropriate for sale and use in the U.S.A. and Canada. Please note the following information:
Your Yamaha model may not be sold in some countries. Therefore, a Yamaha dealer outside the United States or Canada may not have all of the replacement parts or technical information available to provide proper service. This may unavoidably delay repairs. Thank you for your understanding should this happen.

1. As explained in the Limited Warranty Statement, the Yamaha warranty covers your Yamaha when it is registered and used in your country of residence. If you are temporarily using a U.S.-registered outboard motor in Canada, or a Canada- registered outboard motor in the United States, and it needs warranty repairs, you should contact a nearby authorized Yamaha Outboard Motor Dealer for assistance. The local dealer will contact Yamaha on the owners behalf so that needed repairs can be made as quickly as possible.
2. If you need repairs while temporarily using your Yamaha in another country, contact the local authorized Yamaha distributor for that country. Yamaha will work with that distributor to make the needed repairs as quickly as possible. If you have to pay for a repair that you believe your warranty would have covered at home, present all repair orders, receipts, or other related documents to your local dealer when you return home. He will be able to contact Yamaha on your behalf to see if any refund can be provided.
3. If your Yamaha is registered or used primarily outside the United States or Canada, the warranty printed in this manual does not apply to you. Contact the dealer who sold the Yamaha marine power unit to you for customer support information.
