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. EMU33660
Power trim and tilt Body parts can be crushed between the mo- tor and the clamp bracket when the motor is trimmed or tilted. Keep body parts out of this
area at all times. Be sure no one is in this area before operating the power trim and tilt mech- anism. The power trim and tilt switches operate even when the main switch is off. Keep people be away from the switches whenever working around the motor. Never get under the lower unit while it is tilted, even when the tilt support lever is locked. Se- vere injury could occur if the outboard motor accidentally falls. 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 60 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.
U6BR13E0.book Page 1 Monday, November 23, 2009 9:17 AM
Safety information

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.
U6BR13E0.book Page 2 Monday, November 23, 2009 9:17 AM
Safety information

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.

EMU33690
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 USA: 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-
U6BR13E0.book Page 4 Monday, November 23, 2009 9:17 AM
Safety information
5
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 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
U6BR13E0.book Page 5 Monday, November 23, 2009 9:17 AM
Safety information
6
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. 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
U6BR13E0.book Page 6 Monday, November 23, 2009 9:17 AM
Safety information
7
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. EMU33571
Mounting motor
WARNING EWM01570
Improper mounting of the outboard mo- tor could result in hazardous conditions such as poor handling, loss of control, or fire hazards.
Because the motor is very heavy, spe- cial equipment and training is required to mount it safely.
Your dealer or other person experienced in proper rigging should mount the motor using correct equipment and complete rigging in- structions. For further information, see page 52. EMU34952
Digital electronic control re- quirements
The digital electronic control be equipped with a start-in-gear protection device(s). This de- vice prevents the engine from starting unless it is in neutral.

WARNING EWM01580
If the engine starts in gear, the boat can move suddenly and unexpectedly, pos- sibly causing a collision or throwing passengers overboard.
If the engine ever starts in gear, the start-in-gear protection device is not working correctly and you should dis- continue using the outboard. Contact your Yamaha dealer.
This digital electronic control unit is only avail- able for the outboard motor which you have purchased. Prior to use of the digital electronic control unit, set it in order to operate your outboard motor only. Otherwise, it will not be possible to operate the outboard motor. Perform setting of the outboard motor and the digital electronic control unit in the following cases. If a used outboard motor is installed If the digital electronic control unit is re-
placed If the ECM (Electronic control module) of
the used outboard motor is replaced If the ECM (Electronic control module) of
the digital electronic control unit is replaced Consult your Yamaha dealer for setting. EMU25694
Battery requirements EMU25713
Specifications of Battery Use a fully charged battery that meets the fol- lowing specifications. The engine cannot be started if battery voltage is too low.
NOTICE ECM01061
Do not use a battery that does not meet the specified capacity. If a battery that does not meet specifications is used, the elec- tric system could perform poorly or be overloaded, causing electric system dam- age.
EMU36290
Mounting battery Mount the battery holder securely in a dry, well-ventilated, vibration-free location in the boat. WARNING! Do not put flammable items, or loose heavy or metal objects in the same compartment as the battery. Fire, explosion or sparks could result. [EWM01820]
EMU36300
Multiple batteries To connect multiple batteries, such as for mul- tiple engine configurations or for an accessory battery, consult your Yamaha dealer about battery selection and correct wiring. EMU34192
Propeller selection 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 propellers for ev- ery Yamaha outboard motor and every appli- cation.

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 appropri- ate. 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 propeller 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. For instructions on propeller removal and in- stallation, see page 95.
EMU36310
Counter rotation models Standard outboard motors rotate clockwise. Counter rotation models rotate counterclock- wise. Counter rotation models are typically used in multiple motor setups and are marked with an L on the gear case above the anti- ventilation plate.
On counter rotation models, be sure to use a propeller intended for counterclockwise rota- tion. These propellers are identified with the letter L after the size indication on the pro- peller. WARNING! Never use a standard propeller with a counter rotation motor, or a counter rotation propeller with a stan- dard motor. Otherwise the boat could go in the direction opposite of that expected (for example, reverse instead of forward), which could lead to an accident. [EWM01810]
For instructions on propeller removal and in- stallation, see page 96 and 96. EMU35140
Start-in-gear protection Yamaha outboard motors or Yamaha-ap- proved digital electronic control units are equipped with start-in-gear protection de- vice(s). This feature permits the engine to be started only when it is in neutral. Always se- lect neutral before starting the engine. EMU31444
