Safety information Before mounting or operating the outboard
motor, read this entire manual. Reading it should give you an understanding of the motor and its operation.
Before operating the boat, read any own- ers or operators manuals supplied with it and all labels. Be sure you understand each item before operating.
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 man- ufacturer.
Do not modify the outboard. Modifications could make the motor unfit or unsafe to use.
Incorrect propeller selection and incorrect use may not only cause engine damage, but also adversely affect fuel consumption. Consult your dealer for correct use.
Never operate after drinking alcohol or tak- ing drugs. About 50% of all boating fatalities involve intoxication.
Have an approved personal flotation device (PFD) on board for every occupant. It is a good idea to wear a PFD whenever boat- ing. At a minimum, children and non-swim- mers should always wear PFDs, and everyone should wear PFDs when there are potentially hazardous boating condi- tions.
Gasoline is highly flammable, and its va- pors are flammable and explosive. Handle and store gasoline carefully. Make sure there are no gas fumes or leaking fuel be- fore starting the engine.
This product emits exhaust gases which contain carbon monoxide, a colorless, odorless gas which may cause brain dam- age or death when inhaled. Symptoms in- clude nausea, dizziness, and drowsiness. Keep cockpit and cabin areas well ventilat- ed. Avoid blocking exhaust outlets.
Check throttle, shift, and steering for proper operation before starting the engine.
Attach the engine stop switch lanyard cord to a secure place on your clothing, or your arm or leg while operating. If you acciden- tally leave the helm, the cord will pull from the switch, stopping the engine.

Know the marine laws and regulations where you will be boatingand obey them. For basic boating rules, see Rules of the road on page 5.
Stay informed about the weather. Check weather forecasts before boating. Avoid boating in hazardous weather.
Tell someone where you are going: leave a Float Plan with a responsible person. Be sure to cancel the Float Plan when you re- turn.
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.
Always watch carefully for swimmers during the engine operation.
Stay away from swimming areas. When a swimmer is in the water near you
shift into neutral and shut off the engine. Do not illegally discard empty containers
used to replace or replenish oil. For the cor- rect processing of empty containers, con- sult the dealer where you purchased the oil.
When replacing oils used to lubricate the product (engine or gear oil), be sure to wipe away any spilt oil. Never pour oil without us- ing a funnel or similar device. If necessary, verify the necessary replacement proce- dure with the dealer.
Never illegally discard (dump) the product. Yamaha recommends consulting the deal- er on discarding the product.

EMU25500
Basic boating rules (Rules of the road)
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 inter- nationally, and are also enforced by the Unit- ed States Coast Guard and local agencies. You should be aware of these rules, and fol- low them whenever you encounter another vessel on the water. Several sets of rules prevail according to geo- graphic 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 provided for your convenience only. Consult your local U.S. Coast Guard Auxiliary or Department of Motor Vehicles for a complete set of rules governing the waters in which you will be us- ing your boat. EMU25510
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 which does not have the right-of-way is called the give-way or burdened vessel. 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 which 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 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 re- gard shall be had to all dangers of navigation and collision, and to any special circumstanc- es, which may render a departure from the above rules necessary in order to avoid im- mediate 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. EMU25520
Rules when encountering vessels There are three main situations which you may encounter with other vessels which could lead to a collision unless the Steering Rules are followed: Meeting: (you are approaching another ves- sel head-on) Crossing: (you are traveling across the 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
U6D611E0.book Page 5 Friday, March 4, 2005 9:12 AM

6
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 ac- cident. 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.
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. EMU25530
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 which 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 which 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.

Take care not to spill gasoline. If gaso- line spills, wipe it up immediately with dry rags.
Do not overfill the fuel tank. Tighten the filler cap securely after refu-
eling. If you should swallow some gasoline, in-
hale a lot of gasoline vapor, or get gaso- line in your eyes, get immediate medical attention.
If any gasoline spills onto your skin, im- mediately wash with soap and water. Change clothing if gasoline spills on it.
Touch the fuel nozzle to the filler open- ing or funnel to help prevent electrostat- ic sparks.
CAUTION: ECM00010
Use only new clean gasoline which has been stored in clean containers and is not contaminated with water or foreign matter.
EMU25570
Gasoline If knocking or pinging occurs, use a different brand of gasoline or premium unleaded fuel.
Gasohol There are two types of gasohol: gasohol con- taining ethanol and that containing methanol. 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.

Battery requirement
CAUTION: ECM01060
Do not use a battery that does not meet the specified capacity. If a battery which does not meet specifications is used, the elec- tric system could perform poorly or be overloaded, causing electric system dam- age.
For electric start models, choose a battery which meets the following specifications. EMU25711
Battery specifications
NOTE: The engine cannot be started if battery volt- age is too low.
EMU25742
Propeller selection The performance of your outboard motor will be critically affected by your choice of propel- ler, as an incorrect choice could adversely af- fect 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 suitable as it enables the correct engine speed to be main- tained. Conversely, a larger-pitch propeller is more suitable for a smaller operating 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 appli- cation.

NOTE: Select a propeller which will allow the engine to reach the middle or upper half of the oper- ating range at full throttle with the maximum boat load. If operating conditions such as light boat loads then allow the engine r/min to rise above the maximum recommended range, re- duce the throttle setting to maintain the en- gine in the proper operating range.
For instructions on propeller removal and in- stallation, see page 54. EMU25770
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.

Do not overtighten the friction adjuster. If there is too much resistance, it could be difficult to move throttle lever or grip, which could result in an accident.
When constant speed is desired, tighten the adjuster to maintain the desired throttle set- ting. EMU25990
Engine stop lanyard switch The lock plate must be attached to the engine 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 ig- nition to the engine. This will prevent the boat from running away under power.
WARNING EWM00120
Attach the engine stop switch lanyard to a secure place on your clothing, or your arm or leg while operating.
Do not attach the lanyard to clothing that could tear loose. Do not route the lanyard where it could become entan- gled, preventing it from functioning.
Avoid accidentally pulling the lanyard 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 objects in the boat to be thrown forward.
NOTE: The engine cannot be started with the lock plate removed.

Power trim and tilt switch on bottom engine cowling The power trim and tilt switch is located on the side of the bottom engine cowling. Pressing the switch (up) trims the outboard motor up, 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 po- sition.
WARNING EWM01030
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 dis- tract the operator, increasing the risk of collision with another boat or an obstacle.
NOTE: For instructions on using the power trim and tilt switch, see page 36.
EMU30900
Variable trolling RPM switches The trolling speed can be adjusted when the outboard motor is trolling. Press the switch to increase the trolling speed and press the switch to decrease the trolling speed.
NOTE: The trolling speed changes approximately
50 r/min each time a switch is pressed. If the trolling speed has been adjusted, the
engine returns to the normal trolling speed when the engine is stopped and restarted or when the engine speed exceeds approx- imately 3000 r/min.
For instructions on using the variable troll- ing RPM switches, see page 33.

Trim tab with anode 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.
WARNING EWM00840
An improperly adjusted trim tab could cause difficult steering. Always test run af- ter the trim tab has been installed or re- placed to be sure steering is correct. Be sure you have tightened the bolt after ad- justing the trim tab.
If the boat tends to veer the left (port side), turn the trim tab rear end to the port side A in the figure. If the boat tends to veer the right (starboard side), turn the trim tab end to the starboard side B in the figure.
CAUTION: ECM00840
The trim tab also serves as an anode to protect the engine from electrochemical corrosion. Never paint the trim tab as it will become ineffective as an anode.
