Cooling Water Caution System - Suzuki DF350A Owner's Manual

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 "Overheat" and cau-
tion alarm icon are displayed on screen, and
the buzzer sounds. In addition, when this sys-
tem is activated at 2000 r/min. or higher, engine
speed will automatically be reduced to approxi-
mately 2000 r/min.
If you continue to run, the engine will automati-
cally stop 3 minutes after beginning of the
above CAUTION system activation.
NOTE:
In case that the engine is automatically stopped
due to the CAUTION system, the engine can be
started again.
However the CAUTION system will repeatedly
activate until eliminating the cause.
The "Overheat" indication clears when any of
the button is pressed in the gauge. However,
the caution alarm icon is displayed until elimi-
nating the cause.
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 (Overheat)" is not
displayed on screen.
Be aware that "Over Heat (Overheat)" is dis-
played on screen again if engine temperature
rises abnormally. If either of the above situa-
tions 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.
