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...

Page 8

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...

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,

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...

Page 11

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...

Page 12

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...

Page 13

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 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...

Page 20

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

Page 21

Next to selecting an outboard, choosing 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 propel- lers for every Yamaha outboard motor and every application... Your outboard motor came with a Yamaha propeller chosen 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, chose 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, chose 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...

Page 22

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

Page 23

A clean hull improves boat performance... The boat bottom should be kept as clean of ma- rine growth as possible... If necessary, the boat bottom can be coated with an anti-foul- ing 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...

Moving the lever forward from the neutral po- sition engages forward gear... Pulling the le- ver back from neutral engages reverse... The engine will continue to run at idle until the le- ver is moved about 35 (a detent can be felt)... Moving the lever farther opens the throttle, and the engine will begin to accelerate...

Page 27

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 en- tangled, preventing 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

Page 28

The power trim and tilt system adjusts the outboard motor angle in relation to the tran- som... Pressing the switch (up) trims the outboard motor up, and then tilts it up... Press- ing the switch (down) tilts the outboard motor down and trims it down... When the switch is released, the outboard motor will stop in its current position... For instructions on using the power trim and tilt switch, see pages 47 and 49...

Page 29

The power trim and tilt switch is located on the side of the bottom engine cowling... Press- ing the switch (up) trims the outboard motor up, and then tilts it up... Pressing the switch (down) tilts the outboard motor down and trims it down... When the switch is released, the outboard motor will stop in its current position... For instructions on using the power trim and tilt switch, see page 49...

Page 30

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

Page 31

When reinstalling the cowling, ensure that both the front and rear locks have operated properly... If the cowling has not been locked properly, some parts may be damaged by the top cowling

Page 32

To change the display format, press the (mode) button... The display can show total hours or trip hours, or turn off... To reset the trip hours, simultaneously press the (set) and (mode) buttons for more than 1 second while the trip hours are displayed... This resets the trip counter to 0 (zero)... The total number of hours the engine has been run cannot be reset...

Page 33

The speedometer displays km/h, mph, or knots, according to operator preference... Se- lect the desired units of measurement by set- ting the selector switch on the back of the gauge... See the illustration for settings...

Page 34

The fuel level reading can be inaccurate due to by the position of the sensor in the fuel tank and the attitude of the boat in the water... Operation with bow-up trim or continuous turning can give false readings... Do not adjust the selector switch for fuel sen- sor... Incorrectly setting the selector switch on the gauge will give false readings... Consult your Yamaha dealer on how to correctly set the selector switch...

Page 35

If the fuel level decreases to one segment, the fuel level alert segment will blink... Do not continue to operate the engine with full throttle if an alert device has activated... Get back to the port within trolling engine speed...

Page 36

Memorize the trim angles that work best for your boat under different conditions... Adjust the trim angle to the desired setting with the power trim and tilt switch...

Page 37

Do not continue to operate the engine if a alert device has activated... Consult your Yamaha dealer if the problem cannot be

Page 38

The alert for oil filter clogging is similar to the alerts for low oil level and overheating... To make troubleshooting easier, check for en- gine overheating first, then oil level, and fi-

Page 39

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 in- crease, thereby reducing engine efficiency and performance... 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...

Page 40

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 motor is operated con- tinuously in the presence of airborne water spray, enough water could enter the engine through the intake opening on the cowling to cause severe engine damage... Eliminate the cause of the air-

Page 41

3... Next two hours: Accelerate at full throttle onto plane, then reduce engine speed to three-quar- ter throttle (approximately 4000 r/min)... Vary engine speed occasionally... Run at full throttle for one minute, then allow about 10 minutes of operation at three- quarter throttle or less to let the engine cool...

Page 42

Be sure you have plenty of fuel for your trip... A good rule is to use 1/3 of your fuel to get to the destination, 1/3 to return, and to keep 1/ 3 as an emergency reserve... With the boat level on a trailer or in the water, turn the key to (on) and check the fuel level... For fuel filling instructions, see page 40...

Page 43

Operate the throttle levers several times to make sure there is no hesitation in their travel... Operation should be smooth over the complete range of motion, and each le- ver should return completely to the idle po- sition...

Page 44

Never get under the lower unit while it is tilted, even when the tilt support lever is locked... Severe injury could occur if the outboard motor accidentally falls...

Page 45

Check that the battery is in good condition, and fully charged... Check that the battery connections are clean, secure and covered by insulating covers... The electrical contacts of the battery and cables must be clean and properly connected or the battery will not start the engine... Refer to the battery manufacturers instruc- tions for checks for your particular battery...

Page 46

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 indicator seg- ments indicate the status of the oil supply... For details on reading the indicator seg- ments, see page 42...

Page 47

When the engine is operated for the first time or stored for a period of time, a min- imum of 5 liters (5... 3 US qt, 4... 4 Imp qt) of oil should be kept in the remote oil tank... Otherwise the oil-feed pump chamber will not be filled with oil, and no oil will be

Page 48

Buzzer sounds in remote control box and engine speed is limited to about 2000 r/min to help conserve oil...

Page 49

Failure to attached engine shut-off cord could result in a runaway boat if opera- tor is ejected... Attach the engine shut- off cord to a secure place on your cloth- ing, 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, pre- venting it from functioning...

Page 50

using the neutral throttle lever or free ac- celerator... You may need to change the throttle opening slightly depending on engine temperature... After the engine starts, return the throttle to the original position...

Page 51

Never turn the main switch to (start) while the engine is running... Do not keep the starter motor turning for more than 5 seconds... If the starter motor is turned continuously for more than 5 seconds, the battery will be quickly discharged, thus making it impossible to start the engine... The starter can also be damaged... If the engine will not start after 5 seconds of cranking, return the main switch to (on), wait 10 seconds, then crank the engine again...

Page 52

Warm up the engine before shifting into gear... Until the engine is warm, the idle speed may be higher than normal... High idle speed can prevent you from shifting back to neutral... If this occurs, stop the engine, shift to neutral, then restart the

Page 53

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...

Page 54

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...

Page 55

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...

Page 56

Do not use the tilt support lever or knob when trailering the boat... The outboard mo- tor could shake loose from the tilt support and fall... If the motor cannot be trailered in the normal running po- sition, use an additional support de- vice to secure it in the tilt position... For more detailed information, see page 53...

Page 57

Do not tilt the outboard motor up so that the cooling water inlet on the lower unit is above the surface of the water when set- ting up for and cruising in shallow water... Otherwise severe damage from overheat-

Page 58

Yamaha strongly recommends that you use the optional chromium-plated water pump kit (see page 17) if you use the outboard motor in acidic water or water with a lot of sediment in it, such as muddy or turbid (cloudy) water... After operating in such water, flush the cool- ing passages with fresh water to prevent cor- rosion... Also rinse the outside of the outboard motor with fresh water...

Page 59

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...

Page 60

Do not run the engine without supplying it with cooling water... Either the engine wa- ter pump will be damaged or the en- gine will be damaged from overheating... Before starting the en- gine, be sure to supply water to the cooling water passages... Avoid run- ning the outboard motor at high speed while on the flushing attach- ment, otherwise overheating could occur...

Page 61

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 adapter from the garden hose con- nector...

Page 62

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:

Page 63

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 and gear oil... Exam- ples 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...

Page 64

The maintenance cycle on these charts assume usage of 100 hours per year and regular flushing of the cooling water passages... Maintenance frequency should be adjusted when operating the engine under adverse conditions such as extended trolling...

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

Page 68

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...

Page 69

Correct idling speed inspection is only possi- ble if the engine is fully warmed up... If not warmed up fully, the idle speed will measure higher than normal... If you have difficulty ver- ifying the idle speed, or the idle speed re- quires adjustment, consult a Yamaha dealer or other qualified mechanic... 2... Verify whether the idle speed is set to
