Safety information EMU33622

Outboard motor safety Observe these precautions at all times. EMU36501

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 neu- tral, and sharp edges of the propeller can cut even when stationary. Stop the engine when a person is in the wa-

ter near you. Keep people out of reach of the propeller,

even when the engine is off. EMU33630

Rotating parts Hands, feet, hair, jewelry, clothing, PFD straps, etc. can become entangled with inter- nal rotating parts of the engine, resulting in se- rious 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, jewelry, clothing, PFD straps, etc. away from any ex- posed moving parts. EMU33640

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. EMU33650

Electric shock Do not touch any electrical parts while starting or operating the engine. They can cause shock or electrocution. EMU33671

Engine shut-off cord (lanyard) Attach the engine shut-off cord so that the en- gine stops if the operator falls overboard or leaves the helm. This prevents the boat from

running away under power and leaving peo- ple stranded, or running over people or ob- jects. 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 become en- tangled, preventing it from functioning. 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. EMU33810

Gasoline Gasoline and its vapors are highly flam- mable and explosive. Always, refuel accord- ing to the procedure on page 34 to reduce the risk of fire and explosion. EMU33820

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. EMU33900

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 ex- haust outlets.

EMU33780

Modifications Do not attempt to modify this outboard motor. Modifications to your outboard motor may re- duce safety and reliability, and render the out- board unsafe or illegal to use. EMU33740

Boating safety This section includes a few of the many im- portant safety precautions that you should fol- low when boating. EMU33710

Alcohol and drugs Never operate after drinking alcohol or taking drugs. Intoxication is one of the most common factors contributing to boating fatalities. EMU33720

Personal flotation devices Have an approved personal flotation device (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 condi- tions. EMU33731

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 some- one 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. EMU33751

Passengers Consult your boat manufacturers instructions for details about appropriate passenger loca- tions in your boat and be sure all passengers are positioned properly before accelerating

and when operating above an idle speed. Standing or sitting in non-designated loca- tions may result in being thrown either over- board or within the boat due to waves, wakes, or sudden changes in speed or direction. Even when people are positioned properly, alert your passengers if you must make any unusual maneuver. Always avoid jumping waves or wakes. EMU33760

Overloading Do not overload the boat. Consult the boat ca- pacity plate or boat manufacturer for maxi- mum 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. EMU33772

Avoid collisions Scan constantly for people, objects, and other 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, objects, 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 aggressive maneuvers to reduce the risk of loss of con- trol, 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 anoth- er direction.

EMU33790

Weather Stay informed about the weather. Check weather forecasts before boating. Avoid boat- ing in hazardous weather. EMU33800

Accident reporting Boat operators are required by law to file a Boating Accident Report with their state boat- ing 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 oth-

er property over a certain amount. 4. There is complete loss of a boat. Contact local law enforcement personnel if a report is necessary. EMU33870

Boat education and training 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 recognized by the United States Coast Guard. Most, but not all, states accept this course to meet their minimum requirements. While it cannot re- place an in-depth course such as one offered by the U.S. Coast Guard, U.S. Power Squad- ron, or other organization, this online course does provide a general overview of the basics in boating safety, requirements, navigation, and operation. Upon successful completion of the course, the user can download a certifi- cate of completion immediately or, for a small charge, request one by mail. To take this free course, go to boatus.org. EMU33880

Passenger training Make sure at least one other passenger is trained to operate the boat in the event of an emergency. EMU33890

Boating safety publications Be informed about boating safety. Additional publications and information can be obtained from many boating organizations. EMU33590

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.

EMU33691

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 driv- ing your boat. These rules are used interna- tionally. (For U.S.A.: 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 encoun- ter another vessel on the water. EMU33700

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 main- tain 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

U6BV10E0.book Page 4 Friday, July 17, 2009 2:29 PM

Safety information

5

slow down or change directions briefly and pass behind the other vessel. You should al- ways 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 ves- sels. EMU25521

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 fol- lowed: Meeting: (you are approaching another ves- sel head-on) Crossing: (you are traveling across the other 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 shaded 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 col- lision, neither of you has the right-of-way Both of you should alter course to avoid an acci- dent. 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 con- tinue 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 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, provid- ed the other vessel gives you the right-of-way as it should.

U6BV10E0.book Page 5 Friday, July 17, 2009 2:29 PM

Safety 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 another vessel is passing you, you should maintain your speed and direction so that the other vessel can steer itself around you. EMU25531

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 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 nav- igate 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 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 re- gardless of position. Fishing vessels cannot, however, impede the passage of other ves- sels 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, num- bers 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 be- ing entered from seaward (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 navi- gating 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 en- tirely 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 geograph- ic location. Always consult local boating au- thorities before driving your boat in unfamiliar waters.

Installation requirements EMU33563

Boat horsepower rating

WARNING EWM01560

Overpowering a boat can cause severe in- stability.

Before installing the outboard motor(s), con- firm that the total horsepower of your motor(s) does not exceed the boats maximum horse- power rating. See the boats capacity plate or contact the manufacturer. EMU40170

Mounting the outboard motor

WARNING EWM02430

Improper mounting of the outboard motor could result in hazardous conditions, such as poor handling, loss of control, or fire hazards. If you are not able to mount the outboard motor properly, consult a Yamaha dealer.

To lift and mount the outboard motor, two people are necessary. For further information, see page 26. EMU34194

Propeller selection Next to selecting an outboard motor, selecting the right propeller is one of the most important purchasing decisions a boater can make. The type, size, and design of your propeller have a direct impact on acceleration, top speed, fuel economy, and even engine life. Yamaha designs and manufactures propellers for ev- ery Yamaha outboard motor and every appli- cation. 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 ap- propriate. 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 propeller 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 61.

Avoid getting water and contaminants in the fuel tank. Contaminated fuel can cause poor performance or engine dam- age. Use only fresh gasoline that has been stored in clean containers.

Gasohol There are two types of gasohol: gasohol con- taining ethanol (E10) and that containing methanol. Ethanol can be used if the ethanol content does not exceed 10% and the fuel meets the minimum octane ratings. E85 is a fuel containing 85% ethanol and must not be used in your outboard motor. All ethanol blends containing more than 10% ethanol can cause fuel system damage or cause engine starting and running problems. Yamaha does not recommend gasohol containing methanol because it can cause fuel system damage or engine performance problems. It is recommended that you install a water- separating marine fuel filter assembly (10 mi- cron minimum) between your boats fuel tank and outboard motor when using ethanol. Eth- anol is known to allow moisture to be ab- sorbed into boat fuel tanks and systems. Moisture in the fuel can cause corrosion of metallic fuel system components, starting and running complaints and require additional fuel system maintenance. EMU27270

Ring Free Fuel Additive Gasoline is a precise blend of many different substances, each chosen to give certain char- acteristics. Gasoline blends have been changing in recent years in response to con- cerns about pollution and resulting emissions regulations. One of the most obvious changes has been the elimination of lead from most fu- els.

As gasoline has changed, the amount of addi- tives such as aromatics and oxygenates has increased. These additives are important for the engines in passenger cars, but they can have detrimental effects in marine engines, because of increased deposits in the combus- tion chamber. When enough deposits collect, piston rings begin sticking. Performance drops and engine wear increases dramatical- ly. While many additives available may reduce deposits, Yamaha recommends the use of Ring Free Fuel Additive, available from your Yamaha dealer. Ring Free Fuel Additive has repeatedly proven its ability to clean com- bustion deposits from inside the engine, nota- bly the critical piston-ring-land area, and fuel system components. Follow product labeling for use instructions. EMU36330

Anti-fouling paint A clean hull improves boat performance. The boat bottom should be kept as clean of marine growth as possible. If necessary, the boat bot- tom can be coated with an anti-fouling paint approved for your area to inhibit marine growth. Do not use anti-fouling paint which includes copper or graphite. These paints can cause more rapid engine corrosion. EMU36341

Motor disposal requirements Never illegally discard (dump) the motor. Yamaha recommends consulting the dealer about discarding the motor. EMU36351

Emergency equipment Keep the following items onboard in case there is trouble with the motor. A tool kit with assorted screwdrivers, pliers,

wrenches (including metric sizes), and electrical tape.

Engine shut-off cord (lanyard) and clip The clip must be attached to the engine shut- off switch for the engine to run. The cord 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 cord will pull out the clip, stopping ignition to the engine. This will prevent the boat from running away under power. WARNING! At- tach the engine shut-off cord to a secure place on your clothing, or your arm or leg while operating. Do not attach the cord to clothing that could tear loose. Do not route the cord where it could become entangled, preventing it from functioning. Avoid acci- dentally pulling the cord 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 ob- jects in the boat to be thrown forward.

Installation The information presented in this section is in- tended as reference only. It is not possible to provide complete instructions for every possi- ble boat and motor combination. Proper mounting depends in part on experience and the specific boat and motor combination.

WARNING EWM02341

Overpowering a boat could cause se- vere instability. Do not mount an out- board motor with more horsepower than the maximum rating on the capacity 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 conditions, such as poor handling, loss of control, or fire hazards. If you are not able to mount the outboard motor properly, consult a Yamaha dealer.

EMU39562

Mounting the outboard motor

WARNING EWM02300

Do not hold the top cowling or tiller handle when mounting or dismounting the out- board motor. Otherwise, the outboard mo- tor could fall.

1. Be sure to mount the outboard motor while the boat is on land. If the boat is on the water, move it to an area on land.

2. To prevent steering movement, turn the steering friction adjuster clockwise.

3. Turn the tiller handle 180 so that it is pointing rearward.

4. Hold the carrying handle and the hand- grip on the front side of the bottom cowl- ing and lift up the outboard motor using two people.

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

6. Turn the steering friction adjuster coun- terclockwise to set the steering friction according to operator preference. WARNING! If there is too much resis- tance it could be difficult to steer, which could result in an accident. [EWM00721]

EMU39740

Mounting height 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 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 between the bottom of the boat and a level 25 mm (1 in) below it.

NOTICE ECM02170

Check that the idle hole stays high enough to keep out water getting inside engine even if the boat is in stationary with maximum load.

Incorrect engine height or obstructions to the smooth flow of water (such as the design or condition of the boat) can cre- ate airborne water spray while the boat is cruising. If the motor is operated con- tinuously in the presence of airborne water spray, enough water could enter the engine through the intake opening on the top cowling to cause severe en- gine damage. Eliminate the cause of the airborne water spray.

TIP: The optimum mounting height of the out-

board motor is affected by the boat and mo- tor combination and the desired use. Test runs at different heights can help determine the optimum mounting height. Consult your Yamaha dealer or boat manufacturer for further information on determining the prop- er mounting height.

For instructions on setting the trim angle of the outboard motor, see page 41.

EMU39751

Clamping the outboard motor 1. Place the outboard motor on the transom

so that it is positioned as close to the cen- ter as possible. Tighten the clamp screws evenly and securely. Occasionally check the clamp screws for tightness during op- eration of the outboard motor because they could become loose due to engine vibration. WARNING! Loose clamp screws could allow the outboard mo- tor to fall off or move on the transom. This could cause loss of control and

serious injury. Make sure the clamp screws are tightened securely. Occa- sionally check the screws for tight- ness during operation. [EWM00642]

2. Attach one end to the restraint cable at- tachment and the other to a secure mounting point on the boat. Otherwise the engine could be completely lost if it accidentally falls off the transom.

EMU30174

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. [ECM00801]

EMU40060

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 extend- ed idling, rough water and crowded areas.

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: Run the engine at 3000 r/min or at ap- proximately three-quarter throttle.

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 EWM00740

Excessive trim for the operating condi- tions (either trim up or trim down) can cause boat instability and can make steer- ing 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.

The trim angle of the outboard motor helps determine the position of the bow of the boat in the water. The correct trim angle is affected by variables, such as the load in the boat, sea conditions, and running speed.

EMU39272

Adjusting trim angle for manual tilt models

WARNING EWM00400

Stop the engine before adjusting the trim angle.

Use care to avoid being pinched when removing or installing the rod.

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

There are 5 holes provided in the clamp bracket to adjust the outboard motor trim an- gle. 1. Stop the engine. 2. Tilt the outboard motor up, and then re-

move the trim rod from the clamp bracket.

3. Change the position of the trim rod in di- rection A to raise the bow (trim-out). Change the position of the trim rod in di- rection B to lower the bow (trim-in).

TIP: The outboard motor trim angle changes ap- proximately 4 degrees when the trim rod posi- tion is changed by 1 hole. 4. Make test runs with the outboard motor

set at different trim angles to find the po- sition that works best for your boat and operating conditions.

EMU40121

Adjusting boat trim Generally, a boat is stable when the keel line of the boat is up about 3 to 5 degrees. With the bow up, the boat may have a greater ten- dency to steer to one side or the other. If this occurs, adjust the trim angle.

Bow Up Too much trim-out puts the bow of the boat too high in the water. Excessive trim-out can also cause the propeller to ventilate, which re- duces performance further, and the boat may porpoise (hop in the water), which could throw the operator and passengers over- board.

Bow Down Too much trim-in causes the boat to plow through the water, decreasing fuel economy and making it hard to increase speed. Resis- tance at the bow is greatly increased, height- ening the danger of bow steering and making operation difficult and dangerous.

Periodic maintenance

WARNING EWM01981

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 mechan- ic 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 engine

shut-off cord (lanyard) with you when you perform maintenance unless other- wise specified.

Allow the engine to cool before handling hot parts or fluids.

Always completely reassemble the mo- tor before operation.

Maintenance, replacement, or repair of the emission control devices and systems may be performed by any marine engine repair establishment or individual. All war- ranty repairs, however, including those to the emission control system, must be per- formed 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. EMU28511

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 pas-

sengers. Yamaha genuine parts and acces- sories are available from your Yamaha dealer. EMU35520

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, howev- er, if your normal operating conditions are dif- ferent, you should consider service more often than shown, especially how often you change your engine and gear oil. Examples might include extended wide-open-throttle use or long periods of trolling or idling, carry- ing heavy loads, or frequent starting and stop- ping or shifting. More frequent maintenance will often pay off many times over in increased engine life and greater owner satisfaction. Consult your Yamaha dealer for additional maintenance recommendations.

Cleaning and adjusting spark plug The spark plug is an important engine compo- nent. The condition of the spark plug can indi- cate something about the condition of the engine. For example, 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 peri- odically remove 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 cap from the

spark plug.

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 another of the correct type. WARNING! When remov- ing or installing a spark plug, be care- ful not to damage the insulator. A damaged insulator could allow exter- nal sparks, which could lead to explo- sion or fire. [EWM00561]

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 fitting a spark plug, a good estimate of the correct torque is 1/4 to 1/2 a turn past finger- tight. Have the spark plug adjusted to the cor- rect torque as soon as possible with a torque- wrench. EMU39920

Impact damage

WARNING EWM00870

The outboard motor can be seriously dam- aged 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 compo-

nents 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.

EMU39791

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 EWM02361

Use this procedure only for emergency engine starting to return to the nearest port for repairs.

When the emergency starter rope is used to start the engine, the start-in- gear protection device does not operate. Make sure that the shift lever is in the neutral position. 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 that no one is standing be- hind you when pulling the starter rope. It could whip behind you and injure some- one.
