Maintenance
41
CAUTION:
ECM00490
This procedure must be performed while
the outboard motor is in the water. A flush-
ing 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 smoothly.
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 veri-
fying the idle speed, or the idle speed requires
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 32.

Checking propeller
WARNING
EWM00321
You could be seriously injured if the en-
gine accidentally starts when you are near
the propeller.
●
Before inspecting, removing, or install-
ing the propeller, remove the spark plug
caps from the spark plugs. Also, place
the shift control in neutral, turn the main
switch to “
” (off) and remove the key,
and remove the lanyard from the engine
stop switch. Turn off the battery cut-off
switch if your boat has one.
●
Do not use your hand to hold the propel-
ler when loosening or tightening the
propeller nut. Put a wood block between
the anti-cavitation plate and the propel-
ler to prevent the propeller from turning.
