Engine overheat warning
system
The model has an overheat warning
device. If the engine starts to overheat, the
warning light, indicator and “W.TEMP” on
the meter begin to blink and the buzzer
sounds intermittently. If this happens,
reduce the engine speed and return to
beach at low speed. If there is no water dis-
charge at the cooling water pilot outlet while
the engine is running, check the jet intake
and impeller for clogging.
WARNING
Before attempting to remove weeds or
debris from the intake grate or impeller,
shut the engine off and remove the clip
from the engine shut-off switch. Severe
injury or death could result from coming
in contact with the rotating parts of the
jet pump.
CAUTION:
●Return to shore at low speed if the
overheat warning indicator and buzzer
are on, and the display shows
“W.TEMP.” If you ignore these signals,
the engine will stop running and can-
not be restarted until the exhaust sys-
tem cools.
●Have your watercraft inspected and
serviced by a Yamaha dealer if the
engine stopped due to overheating.

If the initial overheat warning is ignored,
engine and exhaust system heat can
increase, particularly if the watercraft contin-
ues to be operated at higher speed. If so,
the warning indicators and buzzer will
change from intermittent to constantly on
and the overheat system will stop ignition to
the engine to reduce the risk of severe over-
heating. The engine cannot be restarted
until it cools down, so it may be necessary to
have the watercraft towed back to the
beach. Refer to “Towing the watercraft” on
page 5-7.
NOTE:
●The buzzer stops sounding if any button
on the meter is pressed.
●Ask a Yamaha dealer to inspect the
watercraft if there is no apparent reason
for overheating.
