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 port engine,
“Port Check Engine” will be displayed and if a
fault is detected for the starboard engine, “St-
bd 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 port engine, “Port Low
Oil Pressure” will be displayed and if a fault is
detected for the starboard engine, “Stbd 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 118 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 tempera-
ture warning system. If the engines start to
overheat, a warning will appear on the multi-
function display and the buzzer will sound. If
the port engine is overheating, “Port Over
Temperature” will be displayed and if the star-
board engine is overheating, “Stbd Over Tem-
perature” will be displayed. At the same time,
the engine speed is automatically limited to
help prevent damage. If this occurs, immedi-
ately reduce the engine speed, return to shore
or maneuver to a safe location, and check for
water discharge at the cooling water pilot out-
lets. There are cooling water pilot outlets on
the starboard side of the hull. Check that wa-
ter comes out of the outlets while the engines
are running, particularly while applying throt-
tle. If you do not see any water at the outlets,
cooling water may not be circulating in the en-
gines.
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 water
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 166.
