OVERHEAT WARNING SYSTEM
The engine has an overheat warning
device. If either engine starts to over-
heat, the engine speed of the affected
engine will be limited to about 3,500 rpm.
Each engine is equipped with cooling-
water pilot outlets on the starboard side
of the hull. Check that water comes out
COURTESY LIGHT
of the outlet while the engine is run-
ning, particularly while applying throt-
tle. If you do not see any water at the
outlet, cooling water may not be circu-
lating in the engine.
NOTE: If water cooling passages on
the engines are dry, it will take about 20
seconds for water to reach the pilot
outlets after starting.

If water is not circulating, something
may be clogging the jet intake grate.
Refer to the Jet Pump Clean-Out pro-
cedures on page 5-5 for further infor-
mation.
If the cause of overheating cannot
be found and corrected, take special
precautions to avoid major engine
damage while you return to shore.
SINGLE ENGINE OVERHEATING —
Shut off the overheating engine and
use the properly running engine to
return to shore. Operate at "no-
wake" speed to prevent water from
flooding the non-operating engine
through the cooling water intake.
