EMU28990
Checking fuel filter
NOTE:
Correct idling speed inspection is only possi-
ble if the engine is fully warmed up. If not
warmed up fully, the idle speed will measure
higher than normal. If you have difficulty ver-
ifying the idle speed, or the idle speed re-
quires adjustment, consult a Yamaha dealer
or other qualified mechanic.
Check the fuel filter periodically. The fuel fil-
ter is a one piece, disposable type. If foreign
matter is found in the filter, replace it. For re-
placement of the fuel filter, consult your
Yamaha dealer.

Verify whether the idle speed is set to
specification. For idle speed specifica-
tions, see page 49.

CAUTION:
q Do not overfill the oil, and be sure the

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. 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.

CAUTION:
Change the engine oil after the first 10
hours of operation, and every 100 hours
or at 6-month intervals thereafter. Other-
wise the engine will wear quickly.

fully in neutral until it is running smooth-
ly.
