General information 2 EMU25272Star labels Your outboard motor is labeled with a Califor- nia Air Resources Board (CARB) star label. See below for a description of your particular label. EMU25280One Star—Low Emission The one-star label identifies engines that meet the Air Resources Board’s 2001 ex- haust emission standards. Engines meeting these standards have 75% lower emissions than conventional carbureted two-stroke en- gines. These engines are equivalent to the U.S. EPA’s 2006 standards for marine en- gines. EMU25290Two Stars—Very Low Emission The two-star label identifies engines that meet the Air Resources Board’s 2004 exhaust emission standards. Engines meeting these standards have 20% lower emissions than One Star-Low-Emission engines. EMU25300Three Stars—Ultra Low Emission The three-star label identifies engines that meet the Air Resources Board’s 2008 ex- haust emission standards. Engines meeting these standards have 65% lower emissions than One Star-Low-Emission engines. 1.

General information 3 EMU25362 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- er’s or operator’s 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 boating—and 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 ZMU01704 U69M15E0.book Page 3 Wednesday, April 5, 2006 4:48 PM
General information 4 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. Be informed about boating safety.

(except 2HP) Do not touch or remove electrical parts when starting or during operation. Keep hands, hair, and clothes away from flywheel and other rotating parts while engine is running.

EMU25465Caution labels EMU25482Label CAUTION: ECM01201 Store the engine only as shown. Otherwise, engine damage could result from leaking oil. 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 Owner’s 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. EMU25510Steering 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. U69M15E0.book Page 5 Wednesday, April 5, 2006 4:48 PM
