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.
1.
Start the engine and allow it to warm up
fully in neutral until it is running smooth-
ly.
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.
2.
Verify whether the idle speed is set to
specification. For idle speed specifica-
tions, see page 40.

Changing engine oil
EWM00760
WARNING
Avoid draining the engine oil immedi-
G
ately after stopping the engine. The oil
is hot and should be handled with care
to avoid burns.

G
fastened to the transom or a stable
stand.

CAUTION:
Do not overfill the oil, and be sure the
G
outboard motor is upright (not tilted)
when checking and changing the en-
gine oil.
If the oil level is above the upper level
G
mark, drain until the level meets the
specified capacity. Overfilling the oil
could cause leakage or damage.

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.

Change the engine oil when the oil is still
warm.
