INSPECTING IDLING SPEED

w

8Keep hands, hair and clothes away from flywheel and other rotating parts while engine is running.

This procedure must be performed while the outboard motor is in the water. A flushing attachment or test tank can also be used.

A diagnostic tachometer should be used for this procedure. Results may vary depending on whether testing is conducted with the flushing attachment, in a test tank, or with the outboard motor in the water.

1)Start the engine and allow it to warm up fully in neutral until it is running smoothly. If the outboard motor is mounted on a boat, be sure the boat is tightly moored.

2)Verify whether the idle speed is set to specification. For idle speed specifica- tions, see “Specifications” in this chapter.

NOTE:

Correct idling speed inspection is only possible if the engine is fully warmed up. If not warmed up fully, the idle speed will measure higher than normal. If you have difficulty verifying the idle speed, or the idle speed requires adjustment, consult a Yamaha dealer or other qualified mechan- ic.
