1 Safety information EMU33622 Outboard motor safety Observe these precautions at all times.EMU36501Propeller 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. EMU33630Rotating 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. EMU33640Hot 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. EMU33650Electric shock Do not touch any electrical parts while starting or operating the engine. They can cause shock or electrocution. EMU33671Engine 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 fromrunning 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. EMU33810Gasoline Gasoline and its vapors are highly flam- mable and explosive. Always, refuel accord- ing to the procedure on page 34 to reduce the risk of fire and explosion. EMU33820Gasoline exposure and spills Take care not to spill gasoline. If gasoline spills, wipe it up immediately with dry rags. Dispose of rags properly. 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. EMU33900Carbon 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. U6BV10E0.book Page 1 Friday, July 17, 2009 2:29 PM
Safety information 2 EMU33780Modifications 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. EMU33710Alcohol and drugs Never operate after drinking alcohol or taking drugs. Intoxication is one of the most common factors contributing to boating fatalities. EMU33720Personal 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. EMU33731People 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. EMU33751Passengers Consult your boat manufacturer’s instructions for details about appropriate passenger loca- tions in your boat and be sure all passengers are positioned properly before acceleratingand 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. EMU33760Overloading 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. EMU33772Avoid collisions Scan constantly for people, objects, and other boats. Be alert for conditions that limit your visibility or block your vision of others. 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. ZMU06025 U6BV10E0.book Page 2 Friday, July 17, 2009 2:29 PM
Safety information 3 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. EMU33790Weather Stay informed about the weather. Check weather forecasts before boating. Avoid boat- ing in hazardous weather. EMU33800Accident 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. EMU33870Boat 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. EMU33880Passenger training Make sure at least one other passenger is trained to operate the boat in the event of an emergency. EMU33890Boating safety publications Be informed about boating safety. Additional publications and information can be obtained from many boating organizations. EMU33590Laws 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. U6BV10E0.book Page 3 Friday, July 17, 2009 2:29 PM
Safety information 4 Contact the U.S. Coast Guard, the National Association of State Boating Law Administra- tors, or your local Power Squadron for a com- plete set of rules governing the waters in which you will be using your boat. EMU33682 Boating organizations The following organizations provide boating safety training and information about boating safety and laws.

Michigan Ave. Chicago, IL 60304 http://www.mraa.com/ EMU33691 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 U.S.A.: 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. EMU33700Steering 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 “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 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 U6BV10E0.book Page 4 Friday, July 17, 2009 2:29 PM
Safety information 5 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. EMU25521Rules 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 vessel’s 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 doesn’t 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 other’s 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.
