OVERHEAT CAUTION SYSTEM
This system is activated when the cylinder wall
temperature is too high due to insufficient water
cooling.
NOTE:
The overheat 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 overheat caution system activates when
operating, reduce engine speed immediately
and check if water is being discharged from the
pilot water hole. If no water is seen, follow 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.
NOTE:
Remember that the overheat caution system
cannot detect overheating caused by, for exam-
ple, an oil system malfunction, poor quality 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 over-
heat caution system may activate.
NOTICE
Operating the engine with the Overheat Cau-
tion System activated can result in severe
engine damage.
If the Overheat Caution System activates, stop
the engine as soon as possible, wind and
water conditions permitting, and inspect the
engine according to the above instructions.
Consult your authorized Suzuki marine dealer
if you cannot correct the problem.
