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 is activated, the system must be RESET before the engine will
operate at higher speeds. Moving throttle lever back to idle position resets 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 temp, 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.
Refer to the Mercury SmartCraft Operator's Supplement provided with the
outboard for the warning functions monitored on your outboard and basic
operation of the SmartCraft Instrument package.

Description
Engine Guardian System is activated.
Power limit will allow a fast idle. The oil
level is critically low in the engine
mounted oil reservoir tank. Refill the
engine mounted oil reservoir tank along
with the remote oil tank. Refer to Fuel
and Oil Section.
Engine Guardian System is activated.
Power limit will allow a fast idle. The
warning horn is activated if the oil
pump should ever stop functioning
electrically. No lubricating oil is being
supplied to the engine.
The warning horn is activated any time
engine speed exceeds the maximum
allowable RPM. The system will limit
the engine speed to within the allow-
able range. Engine overspeed indi-
cates a condition that should be cor-
rected. Overspeed could be caused by
incorrect propeller pitch, engine height,
trim angle, etc.
Engine Guardian System is activated.
Power limit may activate at full throttle
speed.
Engine Guardian System is activated.
Power limit may restrict engine speed
to idle.

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 (a). 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
205 range of travel (b). 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 (c). 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.

POWER TRIM OPERATION

With most boats, operating around the middle of the "trim" range will give
satisfactory results. However, to take full advantage of the trimming capability
there may be times when you choose to trim your outboard all the way in or out.
Along with an improvement in some performance aspects comes a greater
responsibility for the operator, and this is being aware of some potential control
hazards.
