The outboard motor serial number is stamped on the label attached to the port side of the clamp bracket or the upper part of the swivel bracket... Record your outboard motor serial number in the spaces provided to assist you in ordering spare parts from your Yamaha dealer or for reference in case your outboard motor is sto- len...

Page 7

Do not overpower the boat with this out- board motor... Overpowering the boat could result in loss of control... The rated power of the outboard should be equal to or less than the rated horsepower capacity of the boat... If the rated horsepower capacity of the boat is unknown, consult the dealer or boat manufacturer...

Page 8

Use common sense and good judgment when boating... Know your abilities, and be sure you understand how your boat han- dles under the different boating conditions you may encounter... Operate within your limits, and the limits of your boat... Always operate at safe speeds, and keep a careful watch for obstacles and other traffic...

Page 9

Just as there are rules which apply when you are driving on streets and high ways, there are waterway rules which apply when you are driving your boat... These rules are used internationally, and are also enforced by the United States Coast Guard and local agen- cies... You should be aware of these rules, and follow them whenever you encounter another vessel on the water... Several sets of rules prevail according to geographic location, but are all basically the same as the International Rules of the Road... The rules presented here in your Owners Manual are condensed, and have been pro- vided for your convenience only... Consult your local U... S... Coast Guard Auxiliary or De- partment of Motor Vehicles for a complete set of rules governing the waters in which you will be using your boat...

Page 10

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...

Page 11

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...

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

Page 13

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

Page 14

The performance of your outboard motor will be critically affected by your choice of propel- ler, as an incorrect choice could adversely affect performance and could also seriously damage the motor... Engine speed depends on the propeller size and boat load... If engine speed is too high or too low for good engine performance, this will have an adverse effect on the engine... Yamaha outboard motors are fitted with pro- pellers chosen to perform well over a range of applications, but there may be uses where a propeller with a different pitch would be more appropriate... For a greater operating load, a smaller-pitch propeller is more suit- able as it enables the correct engine speed to be maintained... Conversely, a larger-pitch propeller is more suitable for a smaller oper- ating load... Yamaha dealers stock a range of propellers, and can advise you and install a propeller on your outboard that is best suited to your ap- plication...

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 17

The lock plate must be attached to the en- gine stop switch for the engine to run... The lanyard should be attached to a secure place on the operators clothing, or arm or leg... Should the operator fall overboard or leave the helm, the lanyard will pull out the lock plate, stopping ignition to the engine... This will prevent the boat from running away un- der power...

Page 18

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, then tilts it up... Pressing the switch (down) tilts the outboard mo- tor down and trims it down... When the switch is released, the outboard motor will stop in its current position...

Page 19

Use the power trim and tilt switch located on the bottom engine cowling only when the boat is at a complete stop with the en- gine off... Attempting to use this switch while the boat is moving could increase the risk of falling overboard and could distract the operator, increasing the risk of collision with another boat or an obsta-

The warning for oil filter clogging is similar to the warnings for low oil level and overheat- ing... To make troubleshooting easier, check for engine overheating first, then oil level,

Page 29

Incorrect engine height or obstructions to smooth water flow (such as the design or condition of the boat, or accessories such as transom ladders or depth finder transducers) can create airborne water spray while the boat is cruising... Severe engine damage may result if the motor is operated continuously in the presence of

Page 30

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

Page 31

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...

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 33

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 34

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

Page 37

A flow of water from the hole on the ex- haust cover shows that the water pump is pumping water through the cooling pas- sages... If water is not flowing out of the hole at all times while the engine is run- ning, overheating and serious damage could occur... Stop the engine and check whether the cooling water inlet on the lower case or the cooling water pilot hole is blocked... Consult your Yamaha dealer if the problem cannot be located and cor-

Page 38

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...

Page 39

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 40

results in less drag, greater stability and effi- ciency... This is generally when the keel line of the boat is up about 3 to 5 degrees... With the bow up, the boat may have a greater tenden- cy to steer to one side or the other... Compen- sate for this as you steer... The trim tab can also be adjusted to help offset this effect... When the bow of the boat is down, it is easier to accelerate from a standing start onto plane...

Page 41

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...

Page 42

After tilting the outboard motor, be sure to support it with the tilt support knob or tilt support lever... Otherwise the outboard motor could fall back down suddenly if oil in the power trim and tilt unit loses pres-

Page 43

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-

Recommended engine oil: YAMALUBE 2-stroke outboard motor oil

Page 46

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 47

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...

Page 48

3... Change the gear oil... For instructions, see page 55... Inspect the oil for the pres- ence of water which indicates a leaky seal... Seal replacement should be per- formed by an authorized Yamaha dealer prior to use...

Page 49

Do not leave the garden hose connector loose on the bottom cowling fitting or let the hose hang free during normal opera- tion... Water will leak out of the connector instead of cooling the engine, which can cause serious overheating... Be sure the connector is tightened securely on the fit-

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...

When operating in salt water, turbid or muddy water, the engine should be flushed with clean

Page 53

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-

Page 54

ple, if the center electrode porcelain is very white, this could indicate an intake air leak or carburetion problem in that cylinder... Do not attempt to diagnose any problems yourself... Instead, take the outboard motor to a Yamaha dealer... You should periodically re- move and inspect the spark plug because heat and deposits will cause the spark plug to slowly break down and erode... If electrode erosion becomes excessive, or if carbon and other deposits are excessive, you should re- place the spark plug with another of the cor- rect type...

Page 55

3... Remove the filter element, and wash it in solvent... Allow it to dry... Inspect the filter element and O-ring to make sure they are in good condition... Replace them if necessary... If any water is found in the fuel, the Yamaha portable fuel tank or other fuel tanks should be checked and cleaned...

Page 56

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

Page 57

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...

2... Always keep the battery in a good state of charge... Installing a voltmeter will help you monitor your battery... If you will not use the boat for a month or more, re- move the battery from the boat and store it in a cool, dark place... Completely re- charge the battery before using it...

Page 63

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...

Page 64

A problem in the fuel, compression, or igni- tion systems can cause poor starting, loss of power, or other problems... This section de- scribes basic checks and possible remedies, and covers all Yamaha outboard motors... Therefore some items may not apply to your model...
