FEATURES AND CONTROLS

Warning Horn
Function Sound Description
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.
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, 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.
Power Trim And Tilt
Your outboard has a trim/tilt control called power trim. This enables the operator to easily adjust the position of the
outboard by pressing the trim switch. Moving the outboard in closer to the boat transom is called trimming in or
down. Moving the outboard further away from the boat transom is called trimming out or up. The term trim generally
refers to the adjustment of the outboard within the first 20° range of travel. This is the range used while operating
your boat on plane. The term tilt is generally used when referring to adjusting the outboard further up out of the
water. With the engine turned off, the outboard can be tilted out of the water. At low idle speed, the outboard can
also be tilted up past the trim range to permit, for example, shallow water operation.
