the outboard motor is in the water. A
flushing 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 con-
ducted 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 smooth-
ly.
2. Once the engine has warmed up, verify
whether the idle speed is set to specifi-
cation. For idle speed specifications, see
page 10. If you have difficulty verifying
the idle speed, or the idle speed requires
adjustment, consult a Yamaha dealer or
other qualified mechanic.

Changing engine oil
ECM01710
Change the engine oil after the first 20
hours of operation or 3 months, and ev-
ery 100 hours or at 1-year intervals there-
after. Otherwise the engine will wear
quickly.
Extract the engine oil with an oil changer.
1. Put the outboard motor in an upright po-
sition (not tilted). NOTICE: If the out-
board motor is not level, the oil level
indicated on the oil dipstick may not
be accurate.

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
minutes.
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.
If the oil changer is not available, remove the
drain screw while holding a container under
the drain hole. Let the oil drain completely.
Wipe up any spilled oil immediately.
