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 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. 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.
