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 42 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
147.

Low/High voltage warning

If either "Start Battery" or "House Battery" ap-
pears on the multi-function display and the
buzzer will sound, check the battery connec-
tions. If the battery connections are clean and
tight and the warning indication continues,
have a Yamaha Boat Dealer check the charg-
ing system.

Communication error warning

If a communication error is detected for the
GPS function, a sensor, or other device, a
warning will appear on the multi-function dis-
play and the buzzer will sound. If this occurs,
reduce the engine speed, return to shore, and
have a Yamaha Boat Dealer check the boat.

Low fuel level warning

If "Fuel" appears on the multi-function dis-
play and the buzzer will sound, refill the fuel
tank as soon as possible. (See page 88 for in-
formation on filling the fuel tank.)

Depth warning

If the boat enters an area that is shallower
than the water depth set for the depth alarm,
the depth warning will be activated and the
buzzer will sound.
If the warning is activated, move the boat to
an area that is deeper than the water depth
set for the depth alarm. (See page 58 for in-
formation on setting the depth alarm.)
