tivates, the engine will slow down. To switch
off the alert activation on the engine not af-
fected by overheating, turn off the main
switch of the engine overheating. If the alert
system has activated, stop the engine and tilt
the outboard motor up to check the cooling

Low oil pressure alert
If the oil pressure drops too low, the alert de-
vice will activate.
●
The engine speed will automatically de-
crease to about 2000 r/min. The low oil
pressure-alert indicator will light or blink.
●
The buzzer will sound in the same way as
during an overheating alert.
If the alert device has activated, stop the en-
gine as soon as it is safe to do so. Check the
oil level and add oil as needed. If the oil level
is correct and the alert device does not
switch off, consult your Yamaha dealer.

ers:
If the low oil pressure alert system of one en-
gine activates, all of the engines will slow
down and the buzzer will sound. To switch
off the alert activation on the engine(s) not
affected by low oil pressure, turn off the main
switch of the engine with the low oil pressure.
