See the label affixed to your 1 General information G G 1 G ZMU02838 1. Manufactured date label location G Manufactured: G ZMU04346 EMU25362 G Safety information G G G 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 owner'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 outboard 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 manufacturer. G G G 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 taking 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 boating. At a minimum, children and nonswimmers should always wear PFDs, and everyone should wear PFDs when there are potentially hazardous boating conditions. Gasoline is highly flammable, and its vapors are flammable and explosive. Handle and store gasoline carefully. Make sure there are no gas fumes or leaking fuel before starting the engine. This product emits exhaust gases which contain 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 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 accidentally 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 4. 2 General information Stay informed about the weather. Check weather forecasts before boating. Avoid boating in hazardous weather. G Tell someone where you are going: leave a Float Plan with a responsible person. Be sure to cancel the Float Plan when you return. G Use common sense and good judgment when boating. Know your abilities, and be sure you understand how your boat handles 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. G Always watch carefully for swimmers during the engine operation. G Stay away from swimming areas. G When a swimmer is in the water near you shift into neutral and shut off the engine. G Do not illegally discard empty containers used to replace or replenish oil. For the correct processing of empty containers, consult the dealer where you purchased the oil. G When replacing oils used to lubricate the product (engine or gear oil), be sure to wipe away any spilt oil. Never pour oil without using a funnel or similar device. If necessary, verify the necessary replacement procedure with the dealer. G Never illegally discard (dump) the product. Yamaha recommends consulting the dealer on discarding the product.
