while engine is running.

This procedure must be performed while
the outboard motor is in the water. A
flushing attachment or test tank can be
used.
NOTE:
A diagnostic tachometer should be used
for this procedure.
1) Start the engine and allow it to warm
up fully in Neutral until it is running
smoothly.
If the outboard is mounted on a boat,
be sure the boat is tightly moored.
2) Adjust the throttle stop-screw to set
the idling speed to specification (see
"SPECIFICATIONS") by turning the
stop-screw clockwise to increase the
idling speed, and turning it counter-
clockwise to decrease the idling speed.
NOTE:
q
Correct idling-speed adjustment is only
possible if the engine is fully warmed-up.
If not warmed up fully, the speed setting
will tend to be too high.
If you have difficulty obtaining the speci-
fied idle, consult a Yamaha dealer or
other qualified mechanic.
