User manual YAMAHA 5HP-2000

[. . . ] In this Owner's Manual particularly important information is distinguished in the following ways. The Safety Alert Symbol means ATTENTION!YOUR SAFETY IS INVOLVED! EWM00780 your machine and this manual. If there is any question concerning this manual, please consult your Yamaha dealer. NOTE: The F75TR, F90TR and the standard accessories are used as a base for the explanations and illustrations in this manual. [. . . ] Proper mounting depends in part on experience and the specific boat and motor combination. 1 1. Center line (keel line) EMU26930 ZMU01760 Mounting height (boat bottom) To run your boat at optimum efficiency, the water resistance (drag) of the boat and outboard motor must be made as little as possible. The mounting height of the outboard motor greatly affects the water resistance. If the mounting height is too high, cavitation 32 Operation tends to occur, thus reducing the propulsion; and if the propeller tips cut the air, the engine speed will rise abnormally and cause the engine to overheat. If the mounting height is too low, the water resistance will increase and thereby reduce engine efficiency. Mount the outboard motor so that the anti-cavitation plate is in alignment with the bottom of the boat. ECM00800 CAUTION: Failure to follow the break-in procedure could result in reduced engine life or even severe engine damage. EMU27081 Procedure for 4-stroke models Run the engine under load (in gear with a propeller installed) for 10 hours as follows. First hour: Run the engine at 2000 r/min or at approximately half throttle. Second hour: Run the engine at 3000 r/min or at approximately three-quarter throttle. Remaining eight hours: Run the engine at any speed. However, avoid operating at full throttle for more than 5 minutes at a time. After the first 10 hours: Operate the engine normally. EMU27103 ZMU01762 NOTE: G G The optimum mounting height of the outboard motor is affected by the boat/motor combination and the desired use. Securely close the cap after filling the tank. Wipe up any spilled fuel. EMU27450 Operating engine EMU27482 Feeding fuel EWM00420 EMU27270 Ring Free Fuel Additive Gasoline is a precise blend of many different substances, each chosen to give certain characteristics. Gasoline blends have been changing in recent years in response to concerns about pollution and resulting emissions regulations. One of the most obvious changes has been the elimination of lead from most fuels. As gasoline has changed, the amount of additives such as aromatics and oxygenates has increased. These additives are important for the engines in passenger cars, but they can have detrimental effects in marine engines, because of increased deposits in the combustion chamber. When enough deposits collect, piston rings begin sticking. Performance drops and engine wear increases dramatically. While many additives available may reduce deposits, Yamaha recommends the use of Ring Free Fuel Additive, available from your Yamaha dealer. Ring Free Fuel Additive has repeatedly proven its ability to clean combustion deposits from inside the engine, notably the critical piston-ring-land area, and fuel system components. Follow product labeling for use instructions. WARNING G G G Before starting the engine, make sure that the boat is tightly moored and that you can steer clear of any obstructions. [. . . ] Do not install the starter mechanism or top cowling after the engine is running. Do not touch the ignition coil, spark plug wire, spark plug cap, or other electrical components when starting or operating the motor. You could get an electrical shock.
