FEATURES & CONTROLS

The operator is able to correct a couple engine problems indicated
by the warning horn. These conditions are as follows:
Cooling system (water pressure or engine temperature)
problem. The warning horn will sound Intermittent short beeps
for six seconds. Stop the engine and check the water intake
holes in the gearcase for obstruction.
Low oil pressure problem. The warning horn will sound a
continuous six second beep. Stop the engine and check for
low engine oil level. Refer to Fuel and Oil Checking and
Adding Engine Oil.
ENGINE GUARDIAN SYSTEM
The Engine Guardian System monitors the critical sensors on the
engine for any early indications of problems. Engine Guardian is
functional whenever your engine is operating, so you never have
to be concerned about whether or not you are protected. The
system will respond to a problem by sounding the warning horn for
six seconds and/or reducing engine power in order to provide
engine protection.
If the 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
A Mercury SmartCraft System instrument package can be
purchased for this outboard. A few of the functions the instrument
package will display are engine RPM, coolant temperature, oil
pressure, water pressure, battery voltage, fuel consumption and
engine operating hours.
The SmartCraft Instrument package will also aid in Engine
Guardian diagnostics. The SmartCraft Instrument package will
display critical engine alarm data and potential problems.
