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 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. @ @ 4-13 E EMU01742 CHANGING ENGINE OIL WARNING @ G G @ Avoid draining the engine oil immediately after stopping the engine.
