WARNING SYSTEM – MODELS WITH ELECTRONIC FUEL
INJECTION (EFI)
1
The outboard warning system incorporates a warning horn inside the boat. The
warning horn may be located inside the remote control (a) or under the dash
(b) connected to the ignition key switch.
Warning horn signals
When the key switch is turned to the ON position, the horn will turn on for a moment
as a test to tell you the horn is working.
The warning horn will emit either a continuous beep or intermittent short beeps.
This will alert the operator and help identify the following listed situations (see chart
below). For visual display of the specific engine functions and for additional engine
data, refer to SmartCraft Product information on Page 14.

Description
Normal System Test
Oil level is low in the engine mounted
oil reservoir tank. Refil the engine
munted oil reservoir tank along with the
remote oil tank. Refer to Fuel & Oil
Section.
Water in the water–separating fuel filter
reaches the full level. Water can be re-
moved from the filter. Refer to Mainte-
nance Section for filter removal.
Description
Engine Guardian System is activated.
Power limit will vary with level of over-
heat. 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 in-
termittent, stop engine and check water
intake holes for obstruction. The Guard-
ian system must be RESET before en-
gine will operate at higher speeds.
Moving throttle lever back to idle resets
the system.
Engine Guardian System is activated.
Power limit will limit engine speed. 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 will limit engine speed. The
warning horn is activated if the oil
pump should ever stop functioning
electrically. No lubricating oil is being
supplied to the engine.

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, 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 functions some of the instrument packages will display are engine
rpm, coolant temp, 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.
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.

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.

Warning Horn
Description
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.
