Check engine warning
If an engine sensor malfunction or a short cir-
cuit is detected, a warning will appear on the
multi-function display and the buzzer will
sound. If a fault is detected for the engines,
“Check Engine” will be displayed. If this oc-
curs, reduce the engine speed, return to
shore, and have a Yamaha Boat Dealer check
the engine.
Low oil pressure warning
If the oil pressure does not rise to specifica-
tion, a warning will appear on the multi-func-
tion display and the buzzer will sound. If a
fault is detected for the engines, “Low Oil
Pressure” will be displayed. 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 maneu-
ver to a safe location, and check the engine
oil level. (See page 135 for engine 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 suf-
ficient, have a Yamaha Boat Dealer check the
engine.
Over temperature warning
This model is equipped with an over temper-
ature warning system. If the engines start to
overheat, a warning will appear on the multi-
function display and the buzzer will sound. If
the engine is over heating, “Over Tempera-
ture” will be displayed. At the same time, the
engine speed is automatically limited to help
prevent damage. If this occurs, immediately
reduce the engine speed, return to shore or
maneuver to a safe location, and check for
water discharge at the cooling water pilot
outlets. There are cooling water pilot outlets
on the starboard side of the hull. Check that
water comes out of the outlets while the en-
gines are running, particularly while applying
throttle. If you do not see any water at the
outlets, cooling water may not be circulating
in the engines.
1 Cooling water pilot outlet (starboard engine)
2 Cooling water pilot outlet (port engine)
TIP:
If the cooling water passages in the engines
are dry, it will take about 20 seconds for wa-
ter to reach the pilot outlets after starting.
If water is not circulating, something may be
clogging the intake grates. Refer to “Jet
pump clean-out procedure” on page 182.
