The overheat-alert indicator will light or
blink.
●
The buzzer will sound.
If the alert system has activated, stop the en-
gine and check the cooling water inlets:

Check trim angle to be sure that the cooling
water inlet is submerged.

Check the cooling water inlet for clogging.
Dual engine drive users:
If the overheat alert system of one engine ac-

off the alert activation on the engine not affect-
ed by overheating, turn off the main switch of
the engine overheating. If the alert system
