INSPECTING IDLING SPEED

WARNING
@
G Do not touch or remove electrical parts
when starting or during operation.
G Keep hands, hair and clothes away
from flywheel and other rotating parts
while engine is running.
@
CAUTION:
@
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 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
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 chap-
ter.
NOTE:
@
Correct idling speed inspection is only pos-
sible 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
requires adjustment, consult a Yamaha
dealer or other qualified mechanic.
