Cooling Water Caution System - Suzuki DF100 Owner's Manual

NOTICE
Operating the engine with the Oil Pres-
sure Caution System activated can result
in severe engine damage.
If the Oil Pressure Caution System acti-
vates, stop the engine as soon as possi-
ble and add engine oil, if necessary, or
otherwise correct the problem.

COOLING WATER CAUTION SYSTEM

This system is activated when the cylinder wall
temperature is too high due to insufficient water
cooling.
NOTE:
The cooling water caution system will not detect
high combustion chamber temperature caused
by, for example, an oil system malfunction, poor
quality fuel, or spark plugs with an incorrect
heat range.
If this system activates, the red TEMP lamp will
light and the buzzer will begin a series of beep.
In addition, when this system is activated at
3000 r/min. or higher, engine speed will auto-
matically be reduced to approximately 3000
r/min. with REV LIMIT lamp lit.
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 the red TEMP lamp is no
longer lit.
Be aware that the red TEMP lamp may light
again if engine temperature rises abnormally. If
either of the above situations arises, your
authorized Suzuki Marine Dealer must be con-
sulted as soon as possible.
NOTE:
If pilot hole water discharge is sufficient, buzzer
and TEMP lamp may still operate until engine
temperature decreases. Run engine in NEU-
TRAL only until the caution systems are can-
celled.
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.
