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 engine,
“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 engine, “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 81 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
If the engine starts to overheat, a warning will
appear on the multi-function display and the
buzzer will sound. If the engine is overheat-
ing, “Over Temperature” will be displayed. At
the same time, the engine speed is automat-
ically 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 engine is running, particular-
ly while applying throttle. If you do not see
any water at the outlets, cooling water may
not be circulating in the engine.

Cooling water pilot outlet
TIP:
The number of cooling water pilot outlets
varies according to the model.
AR195/SX195: 3 cooling water pilot outlets
AR190/SX190: 1 cooling water pilot outlet
If the cooling water passages in the engine
are dry, it will take about 20 seconds for
water to reach the pilot outlets after start-
ing.
If water is not circulating, something may be
clogging the intake grate. Refer to “Jet pump
clean-out procedure” on page 128.
