when starting or during operation.
 Keep hands, hair, and clothes away from
the flywheel and other rotating parts
while the engine is running.
NOTICE
This procedure must be performed while
the outboard motor is in the water. A flush-
ing attachment or test tank can be used.
If the boat is not equipped with a tachometer
for the outboard motor, use a diagnostic ta-
chometer for this procedure. Results may
vary depending on whether testing is conduct-
ed 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.
2. Start the engine. Warm it up and keep the
idle speed for 5-10 minutes.
3. Stop the engine and leave it for 5-10 min-
utes.
4. Remove the top cowling.
5. Remove the oil filler cap. Pull out the dip-
stick and use the oil changer to extract
the oil completely.
2. Once the engine has warmed up, verify
whether the idle speed is set to specifica-
tion. For idle speed specifications, see
page 10. If you have difficulty verifying
the idle speed, or the idle speed requires
adjustment, consult a Outboards dealer or
other qualified mechanic.
