User manual YAMAHA T8HP-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! CAUTION: 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. @ @ Yamaha continually seeks advancements in product design and quality. Therefore, while this manual contains the most current product information available at the time of printing, there may be minor discrepancies between your machine and this manual. [. . . ] When operating in salt water, turbid or muddy water, the engine should be flushed with clean water after each use. NOTE: If leaded gasoline is usually used, engine valves and related parts should be inspected after every 300 hours of operation in addition to the items on the maintenance chart above. @" @ 4-11 E EMU00366 GREASING Yamaha marine grease (Water resistant grease) 4-12 E EMU01202 CLEANING AND ADJUSTING SPARK PLUG WARNING @ When removing or installing a spark plug, be careful not to damage the insulator. A damaged insulator could allow external sparks, which could lead to explosion or fire. @ The spark plug is an important engine component and is easy to inspect. The condition of the spark plug can indicate something about the condition of the engine. For example, if the center electrode porcelain is very white, this could indicate an intake air leak or carburetion problem in that cylinder. Do not attempt to diagnose any problems yourself. Instead, take the outboard motor to a Yamaha dealer. You should periodically remove and inspect the spark plug because heat and deposits will cause the spark plug to slowly break down and erode. If electrode erosion becomes excessive, or if carbon and other deposits are excessive, you should replace the spark plug with another of the correct type. Standard spark plug: Refer to "SPECIFICATIONS", page 4-1. Before fitting the spark plug, measure the electrode gap with a wire thickness gauge; adjust the gap to specification if necessary. Spark plug gap: Refer to "SPECIFICATIONS", page 4-1. 4-13 E When fitting the plug, always clean the gasket surface and use a new gasket. Keep hands, hair and clothes away from flywheel and other rotating parts while engine is running. @ CAUTION: @ This procedure must be performed while the outboard motor is in the water. A flushing attachment or test tank can be used. @ A diagnostic tachometer should be used for this procedure. 1) Start the engine and allow it to warm up fully in Neutral until it is running smoothly. If the outboard is mounted on a boat, be sure the boat is tightly moored. 2) Adjust the throttle stop-screw 1 to set the idling speed to specification (see "SPECIFICATIONS" on page 4-1) by turning the stop-screw clockwise to increase the idling speed, and turning it counterclockwise to decrease the idling speed. NOTE: Correct idling-speed adjustment is only possible if the engine is fully warmed-up. If not warmed up fully, the speed setting will tend to be too high. If you have difficulty obtaining the specified idle, consult a Yamaha dealer or other qualified mechanic. @ @ 4-17 E EMU01415¯ CHANGING ENGINE OIL WARNING @ G G @ Avoid draining the engine oil immediately after stopping the engine. The oil is hot and should be handled with care to avoid burns. Be sure the outboard is securely fastened to the transom or a stable stand. CAUTION: @ G G G Change the engine oil after the first 10 hours of operation, and every 100 hours or at 6-month intervals thereafter. Otherwise, the engine will wear quickly.
