NOTICE
If the cause of overheating cannot be
found and corrected, take special precau-
tions 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 (8 km/h, 5 mph) to pre-
vent water from flooding the non-operat-
ing engine through the water intake. See
page 51 for information on the no-wake
mode.
Both engines overheating — If getting a
tow from another vessel 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 144.
TIP:
Press either the M or T button on the multi-
function tachometer to stop the buzzer.
Engine oil pressure low warning
If the oil pressure does not rise to specifica-
tion, “
Low Oil Press” will appear on the LCD
of the multi-function tachometer for the affect-
ed engine and the buzzer will sound intermit-
tently. At the same time, the engine speed is
automatically limited to help prevent damage.
If this occurs, reduce the engine speed, return
to shore or maneuver to a safe location, and
check the engine oil level (see page 85 for en-
gine oil level checking procedures). If the oil
level is low, add enough engine oil to raise it
to the proper level. If the oil level is sufficient,
have a Yamaha Boat Dealer check the en-
gine.
Check engine warning
If an engine sensor malfunction or a short cir-
cuit is detected, “
Check Engine” will appear
on the LCD of the multi-function tachometer
for the affected engine and the buzzer will
sound intermittently. If this occurs, reduce the
engine speed, return to shore, and have a
Yamaha Boat Dealer check the engine.
Low/high battery voltage warning
If either “Batt Voltage” or “Aux Voltage” ap-
pears on the LCDs of the multi-function ta-
chometers, check the battery connections. If
the battery connections are clean and tight
and the warning indication continues, have a
Yamaha Boat Dealer check the charging sys-
tem.
Low fuel level warning
If “
Low Fuel Level” appears on the LCDs of
the multi-function tachometers, refill the fuel
tank as soon as possible. (See page 83 for in-
formation on filling the fuel tank.)
