General information 2 EMU25262Manufactured date label This label is attached to the clamp bracket or the swivel bracket. 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. 1. Manufactured date label location Manufactured: ZMU04346 1. Star labels location ZMU01702 U6P213E0.book Page 2 Thursday, March 9, 2006 10:20 AM
General information 3 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. 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 thanthe 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. ZMU01703 ZMU01704 U6P213E0.book Page 3 Thursday, March 9, 2006 10:20 AM
General information 4 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 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.
