User manual YAMAHA 130HP-2001

[. . . ] In this Owner's Manual particularly important information is distinguished in the following ways. The Safety Alert Symbol means ATTENTION!YOUR SAFETY IS INVOLVED! cC A CAUTION indicates special precautions that must be taken to avoid damage to the outboard motor. NOTE: A NOTE provides key information to make procedures easier or clearer. [. . . ] Performance and economy are decreased because the hull of the boat is pushing the water and there is more air drag. Excessive trim-up can cause the propeller to ventilate, which reduces performance further. When trimmed-out too much, a boat may "porpoise" (hop in the water), which could throw the operator and passengers overboard. EMU00283 Bow Down When the bow of the boat is down, it is easier to accelerate from a standing start onto plane. Too much trim-in causes the boat to "plow" through the water, decreasing fuel economy and making in hard to increase speed. Operating with excessive trim-in at higher speeds also makes the boat unstable. Resistance at the bow is greatly increased, heightening the danger of "bow steering" and making operation difficult and dangerous. 1 Bow up 2 Bow down 3 Optimum angle 105013 e 105015 3-20 E EMH40011 DUAL ENGINE INSTALLATION/SINGLE ENGINE RUNNING Using only one of the engines in case of emergency, be sure to keep the unused one tilted up and operate the other engine at low speed. 102043 cC 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. 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. Then, if the engine you are using stops, you can immediately switch to the other engine. 3-21 E EMU01200 TILTING UP/DOWN If the engine will be stopped for some time, or if the boat is moored in shallows, the engine should be tilted up to protect the propeller and casing from damage by collision with obstructions, and also to reduce salt corrosion. 000817 cC Before tilting the motor, follow the procedures under "STOPPING ENGINE". Never tilt the motor while the engine is running. Severe damage from overheating can result. w Be sure all people are clear of the outboard motor when adjusting the tilt angle, also be careful not to pinch any body parts between the drive unit and engine bracket. w Leaking fuel is a fire hazard. Disconnect the fuel line or close the fuel cock if the engine will be tilted for more than a few minutes. Perform the flushing and fogging at the same time. 1) Remove the top cowling and silencer cover. 2) Install a flushing attachment to the lower unit. (Flushing attachment available from your Yamaha dealer). 605014 cC Avoid running the outboard at high rpm while on the flushing attachment or overheating could occur. w 8 Do not touch or remove electrical parts when starting or during operation. 8 Keep hands, hair and clothes away from flywheel and other rotating parts while engine is running. 3) Run the engine at a fast idle for 10~15 minutes. 4) Just prior to turning off the engine, quickly spray "Yamaha Stor-Rite Engine Fogging Oil (Part No. LUB-STRRT-1200) alternately into each carburetor. When properly done, the engine will smoke excessively and almost stall. 5) Remove the flushing attachment and wipe off any excess water. 6) Install the silencer cover and top cowling.
