OVERHEAT WARNING SYSTEM
The engine has an overheat warning
device. If the engine starts to overheat,
the engine speed will be limited to about
3,500 rpm.
The engine is equipped with a cooling-
water pilot outlet on the starboard side
of the hull. Check that water comes out
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
outlet 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 5-4 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.
If getting a tow from another vessel
is not possible, operate engine just
slightly above idle while you return
to shore. If you can be towed, refer
to "Towing the Jet Boat" on page 5-
3.
