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 problem will need to be identified
and corrected, if possible. The system must be reset before the engine will operate at higher speeds.
Moving the throttle lever back to the idle position will reset the system.
SMARTCRAFT PRODUCT

functions the instrument package will display are engine RPM, coolant temperature, oil pressure, water

corrected. Overspeed
could be caused by
incorrect propeller pitch,
engine height, trim angle,
tilt angle (shallow water
operation) etc.
