[. . . ] 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.

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. Damage could make the outboard motor unsafe to operate. If the outboard motor hits an object in the water, follow the procedure below. 64 Trouble Recovery EMU29470 Replacing fuse If a fuse has blown, remove the electrical cover, open the fuse holder and remove the fuse with a fuse puller (if equipped).
