cally limited to help prevent damage. If this oc-
curs, 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 pi-
lot outlets on the starboard side of the hull.
Check that water comes out of the outlets
while the engines 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 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 178.
1 Intake grate
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 50 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 184.
