System for filter removal.
Cooling System Problem Continuous Engine Guardian System is activated. Power
limit will vary with level of overheat. Shift
outboard into neutral and check for a steady
stream of water coming out of the water pump
indicator hole. If no water is coming out of the
water pump indicator hole or flow is
intermittent, stop engine and check water
intake holes for obstruction. The Guardian
System must be RESET before engine will
operate at higher speeds. Moving throttle
lever back to idle resets the system.
Oil Level is Critically Low Continuous Engine Guardian System is activated. Power
will be limited. The oil level is critically low in
the engine mounted oil reservoir. Refill the
engine mounted oil reservoir along with the
remote oil tank.
Oil Pump Failure Continuous Engine Guardian System is activated. Power
will be limited. The warning horn is activated
if the oil pump should ever stop functioning
electrically. No lubricating oil is being
supplied to the engine.
Engine Overspeed Continuous The warning horn is activated any time
engine speed exceeds the maximum
allowable RPM. The system will limit the
engine speed to within the allowable range.
Engine overspeed indicates a condition that
should be corrected. Overspeed could be
caused by incorrect propeller pitch, engine
height, trim angle, etc.
Sensor out of Range Continuous Engine Guardian System is activated. Power
will be limited.
Intermittent Beep
ENGINE GUARDIAN SYSTEM
The Engine Guardian System monitors the critical sensors on the engine for any early indications of
problems. The system will respond to a problem by emitting a continuous beep and/or reducing engine
power in order to provide engine protection.
If Guardian System has been activated, reduce throttle speed. The horn will turn off when throttle speed
is within the allowable limit. Consult your dealer for assistance.
