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 3000 rpm.
Each engine is equipped with cooling-
water pilot outlets  on the starboard
side of the hull. Check that water comes
out of the outlet while the engine is run-
ning, particularly while applying throttle.
If you do not see any water at the out-
let, cooling water may not be circulating
in the engine.

tip: 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. See page
2-14 for "no Wake mode" system
operation.
Both EnGinES oVErhEatinG —
if getting a tow from another ves-
sel is not possible, operate both
engines just slightly above idle while
you return to shore. if you can be
towed, refer to "towing the boat" on
page 5-3.
