If the cooling water caution system activates
when operating, reduce engine speed immedi-
ately and check if water is being discharged
from the pilot water hole. If no water is seen, fol-
low the procedures outlined below.
Water and wind conditions permitting, stop the
engine, tilt it out of the water and remove any
debris like seaweed, plastic bags or sand that
may have blocked the water intakes.
Lower the engine into the water, being sure that
water intakes are immersed, and restart it.
Check (A) that water discharges from the pilot
hole and (B) that "Over Heat" is not displayed
on screen.
Be aware that "Over Heat" is displayed on
screen again if engine temperature rises abnor-
mally. If either of the above situations arises,
your authorized Suzuki Marine Dealer must be
consulted as soon as possible.
NOTE:
If pilot hole water discharge is sufficient, buzzer
and display on screen may still operate until
engine temperature decreases. Run engine in
NEUTRAL only until the caution systems are
cancelled.

NOTICE
Operating the engine with the Cooling
Water Caution System activated can
result in severe engine damage.
If the Cooling Water Caution System acti-
vates, stop the engine as soon as possi-
ble, wind and
permitting, and inspect the engine
according to the above instructions. Con-
sult your authorized Suzuki marine dealer
if you cannot correct the problem.
NOTE:
Remember that the cooling water caution sys-
tem cannot detect overheating caused by, for
example, an oil system malfunction, poor qual-
ity fuel, or incorrect spark plugs.
NOTE:
If the engine is operated beyond the maximum
trim position, the water intake holes may be
above the water line. In this situation, the cool-
ing water caution system may activate.
