Warming up engine

Procedure for warming up engine
1.
After starting the engine, warm up the
engine until the engine speed stabilizes
at idle speed to provide maximum oper-
ating performance and acceleration.
NOTICE:
Failure to do so will shorten
engine life.

2.
Check that the low oil pressure-alert indi-
cator remains off.
NOTICE:
If the low oil
pressure-alert indicator blinks after
the engine starts, stop the engine.
Otherwise, serious engine damage
could occur. Consult your Yamaha
dealer.

Shifting
WARNING
EWM00181
Before shifting, make sure there are no
swimmers or obstacles in the water near
you.
NOTICE
ECM01611
Warm up the engine before shifting into
gear. Until the engine is warm, the idle
speed may be higher than normal. High
idle speed can prevent you from shifting
back to neutral. If this occurs, stop the en-
gine, shift to neutral, then restart the en-
gine and allow it to warm up.
To shift out of neutral
1.
Pull the neutral interlock trigger up (if
equipped).
2.
Move the remote control lever / gear shift
lever firmly and crisply forward (for for-
ward gear) or backward (for reverse gear)
[about 35° (a detent can felt) for remote
control models].
