NOTE: The F150TR, LF150TR and the standard accessories are used as a base for the explanations and illustrations in this manual. [. . . ] Mount the outboard motor on the center line (keel line) of the boat, and ensure that the boat itself is well balanced. Otherwise the boat will be hard to steer. For boats without a keel or which are asymmetrical, consult your dealer. CAUTION: Incorrect engine height or obstructions to smooth water flow (such as the design or condition of the boat, or accessories such as transom ladders or depth finder transducers) can create airborne water spray while the boat is cruising. Severe engine damage may result if the motor is operated continuously in the presence of airborne water spray. NOTE: During water testing check the buoyancy of the boat, at rest, with its maximum load. Check that the static water level on the exhaust housing is low enough to prevent water entry into the powerhead, when water rises due to waves when the outboard is not running. EMU26910 Mounting the outboard motor EWM00820 WARNING G G Overpowering a boat could cause severe instability. Do not install an outboard motor with more horsepower than the maximum rating on the capacity plate of the boat. If the boat does not have a capacity plate, consult the boat manufacturer. The information presented in this section is intended as reference only. It is not possible to provide complete instructions for every possible boat and motor combination. Proper mounting depends in part on experience and the specific boat and motor combination. 1 1. Center line (keel line) ZMU01760 27 Operation NOTE: G 1. Be sure the fuel tank is positioned on a secure, flat surface, and that the fuel line is not twisted or flattened, or likely to contact sharp objects (if equipped Yamaha fuel tank or boat tank). Check throttle, shift, and steering for proper operation before starting the engine. The controls should work smoothly, without binding or unusual free play. Check operation of the starter and stop switches when the outboard motor is in the water. Upper level mark EMU27130 NOTE: Be sure to completely insert the dipstick into the dipstick guide. EMU30021 Controls G G Filling fuel EWM00060 G G WARNING Gasoline and its vapors are highly flammable and explosive. Keep away from sparks, cigarettes, flames, or other sources of ignition. Carefully fill the fuel tank. EMU27150 Engine G G G 29 Operation 3. Securely close the cap after filling the tank. Wipe up any spilled fuel. G 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. [. . . ] 2. 3. 4. Stop the engine immediately. Inspect the control system and all components for damage. Whether damage is found or not, return to the nearest harbor slowly and carefully. Have a Yamaha dealer inspect the outboard motor before operating it again. EMU29450 Running single engine When using only engine in an emergency, be sure to keep the unused one tilted up and operate the other engine at low speed. ECM00370 CAUTION: If the boat is operated with one engine in the water but not running, water may run into the exhaust pipe due to wave action, causing engine trouble. Temporary action in emergency EMU29440 Impact damage EWM00870 NOTE: When you are maneuvering at low speed, such as near a dock, it is recommended that both engines be running with one in neutral gear if possible. WARNING The outboard motor can be seriously damaged by a collision while operating or trailering. [. . . ]
