Water Separator Alert - Yamaha F150G Owner's Manual

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.
Twin engine drive users:
If the low oil pressure alert system of one en-
gine activates, both engines will slow down
and the buzzer will sound. To switch off the
alert activation on the engine not affected by
low oil pressure, turn off the main switch of
the engine with the low oil pressure.
