If no water is coming out of the water pump indicator hole, or flow is
intermittent, stop the engine and check the cooling water intake holes for
obstruction. If no obstruction is found, there may be a blockage in the cooling
system or a water pump problem. Operating the engine while overheated will
cause engine damage.
If a steady flow of water is coming out of the water pump indicator hole and the
engine continues to overheat, service is required. Operating an overheated
engine will cause engine damage.
NOTE: Should overheating occur and you are stranded, stop the engine and
allow it to cool down. This will usually allow some additional low speed (idle)
running time before the engine starts to overheat again.
LOW OIL PRESSURE
The warning system will be activated if the oil pressure drops too low. First,
stop the engine and check the oil level. Add oil if necessary. If the oil level is
within the operating range and the warning horn continues to sound, service is
required. Engine speed will be limited to 2800 RPM, however, you should not
continue to run the engine.
ENGINE OVERSPEED LIMITER
Some causes of engine overspeed are as follows:
•
Propeller ventilation
•
A propeller that has an incorrect pitch or diameter
•
Propeller hub slippage
•
Outboard mounted too high on the transom
•
Tilting the outboard out beyond a vertical position
•
Cavitation of the propeller due to rough water or obstruction in the boat
hull
When the engine overspeed limiter is activated, the engine timing will be
momentarily retarded to decrease the engine speed. Excessive overspeed will
result in the momentary removal of ignition to prevent operation above the RPM
limit. Refer to

SENSOR AND RESTRICTOR ERROR
The computer controlled CDI (capacitor discharge ignition) monitors various
sensors on the engine and when a sensor is not within the normal operating
range, the computer controlled CDI will limit the engine RPM to 2800, the
warning light will flash, and the warning horn will beep six times every five
minutes.
A restrictor in the air intake induction system restricts the amount of air that can
enter the induction system. The restrictor cannot be removed to gain more
horsepower. If the restrictor is removed, the computer controlled CDI will limit
the engine RPM to 2800, the warning light will flash, and the warning horn will
beep six times every five minutes.
