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 wa-
ter to reach the pilot outlets after starting.
If water is not circulating, something may be
clogging the intake grate. Refer to “Jet pump
clean-out procedure” on page 124.

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.
If getting a tow from another vessel is not
possible, operate engine just slightly
above idle while you return to shore. If you
can be towed, refer to “Towing the boat”
on page 128.
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
and the buzzer will sound intermittently. 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 76 for engine oil lev-
el 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 engine.
Check engine warning
If an engine sensor malfunction or a short cir-
cuit is detected, “
Check Engine” will appear
on the LCD and the buzzer will sound intermit-
tently. 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 LCD, 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.
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 75 for in-
formation on filling the fuel tank.)
