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

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

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,

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... EMU44181

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

Page 12

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

Page 13

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...

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...

Page 24

Start-in-gear protection Yamaha outboard motors or Yamaha-ap- proved remote control units are equipped with start-in-gear protection device(s)... This feature permits the engine to be started only when it is in neutral... Always select neutral before starting the engine... EMU41953

Page 25

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...

Page 26

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

TIP: The neutral throttle lever will operate only when the remote control lever is in neutral... The remote control lever will operate only when the neutral throttle lever is in the closed position... EMU25914

Page 37

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 en-

Page 38

Main switch The main switch controls the ignition system; its operation is described below... (off) With the main switch in the (off) posi- tion, the electrical circuits are off, and the key can be removed... (on) With the main switch in the (on) posi- tion, the electrical circuits are on, and the key cannot be removed... (start) With the main switch in the (start) po- sition, the starter motor turns to start the en- gine... When the key is released, it returns automatically to the (on) position...

Page 39

Power trim and tilt switch on remote control or tiller handle 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 69 and 71... ZMU02810

Page 40

Power trim and tilt switch on bottom cowling The power trim and tilt switch is located on the side of the bottom cowling... Pushing the switch (up) trims the outboard motor up, and then tilts it up... Pushing 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 po- sition... For instructions on using the power trim and tilt switch, see page 71...

Page 41

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...

Speedometer 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 47

The fuel level reading can be inaccurate due to the position of the sensor in the fuel tank and the attitude of the boat in the water... Op- eration with bow-up trim or continuous turn- ing 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... NOTICE: Running out of fuel can damage the engine... [ECM01771]

Adjusting trolling speed You can adjust the trolling speed randomly by increasing or decreasing it approximately 50 r/min... When in the trolling speed setting mode, the display switches to the normal dis- play when the engine speed is increased (within 3000 r/min) using the throttle... When the throttle is closed, the display returns to the trolling speed setting mode... For details, see the attached operation manual...

Page 52

Water separator alert This indicator will blink if water has accumu- lated in the water separator (fuel filter) while cruising... In such an event, stop the engine immediately and see page 97 of this manual to drain the water from the fuel filter... Get back to the port soon and consult a Yamaha dealer immediately...

Overheat alert This engine has an overheat-alert device... If the engine temperature rises too high, the alert device will activate... The engine speed will automatically de-

Page 57

If the alert system has activated, stop the en- gine as soon as it is safe to do so... Check the oil level and add oil as needed... If the oil level is correct and the alert device does not switch off, consult your Yamaha dealer...

Page 58

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...

Page 59

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...

Page 60

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]

Page 61

Fuel level 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 lev- el on a trailer or in the water, turn the key to (on) and check the fuel level... For fuel filling instructions, see page 58... EMU36573

Page 62

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 63

Flushing device Check that the flushing devices garden hose connector is securely screwed on to the fit- ting on the bottom cowling... NOTICE: If the garden hose connector is not properly connected, cooling water can leak out and the engine can overheat during oper- ation... [ECM01802]

Page 64

Battery 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... EMU43164

Page 65

Gasoline is poisonous and can cause injury or death... Handle gasoline with care... Never siphon gasoline by mouth... If you should swallow some gasoline or inhale a lot of gasoline vapor, or get some gasoline in your eyes, see your doctor immediately... If gasoline spills on your skin, wash with soap and wa- ter... If gasoline spills on your clothing, change your clothes...

Otherwise, serious engine damage could occur... Check the oil level and add engine oil if necessary... Consult your Yamaha dealer if the cause for the low oil pressure alert cannot be found... [ECM01832]

Page 72

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 engine and allow it to warm up...

Page 73

The boat is not equipped with a separate braking system... Water resistance stops it af- ter the throttle lever is moved back to idle... The stopping distance varies depending on gross weight, water surface conditions, and wind direction... EMU30881

Stopping engine Before stopping the engine, first let it cool off for a few minutes at idle or low speed... Stop- ping the engine immediately after operating at high speed is not recommended... EMU43192

Page 75

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

Page 76

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...

Page 77

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...

Page 78

3... Pull the tilt support lever toward you to support the engine... WARNING! After tilting the outboard motor, be sure to support it with the tilt support knob or tilt support lever... Otherwise the out- board motor could fall back down suddenly if oil in the power trim and tilt unit or in the power tilt unit loses pressure... [EWM00263] NOTICE: Do not use the tilt support lever or knob when trailering the boat... The outboard mo-

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...

Page 82

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]

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...

Instead, take the outboard motor to a Yamaha dealer... You should periodically re-
