EMU29040
Inspecting idling speed
WARNING
EWM00450
●
Do not touch or remove electrical parts
when starting or during operation.
●
Keep hands, hair, and clothes away
from the flywheel and other rotating
parts while the engine is running.
●
2-hp models: The propeller rotates
whenever the engine is running. Do not
move the throttle control lever from the
start position during warm-up. The boat
could unexpectedly start to move,
which could result in an accident.
CAUTION:
ECM00490
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.
2-hp model: Warm the engine with the
throttle in the start position or less. If the
outboard is mounted on a boat, be sure
the boat is tightly moored.
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 33.
