WARNING SYSTEM

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
connected to the ignition key switch (b).
Warning System Operation
If the engine overheats or the oil pressure drops too low, the warning system will
be activated. The warning horn will sound continuously and engine speed will be
limited to 2000 RPM.
Warning System Activated
2
If the warning system is activated, immediately reduce engine speed to idle.
Shift outboard into neutral and visually check for a steady flow of water
discharging from the water pump indicator hole. If no water is flowing out, the
water pump is not working and the engine is overheating. See Engine
Overheat explanation on the next page.
If water is discharging from the water pump indicator hole, stop engine and
check the oil level. A low oil pressure problem may exist. See Low Oil
Pressure explanation on the next page.

WARNING SYSTEM
Engine Overheat
Stop the engine. If no water is coming out of the water pump indicator hole or flow
is intermittent, check the cooling water intake holes for obstruction. If no
obstruction is found, there may be a blockage in the cooling system or a water
pump problem. Have your dealer check the outboard. Operating an overheated
engine will cause engine damage. See the following note.
If a steady flow of water is coming out of the water pump indicator hole and the
engine continues to overheat, consult your dealer. Operating an overheated
engine will cause engine damage. See the following note.
Note: Should overheating occur and you are stranded, stop the engine and allow
it to cool down this will usually allow some additional low speed (idle) running time
before the engine starts to overheat again.

Low Oil Pressure
The warning system will be activated if the oil pressure drops too low. First, stop
the engine and check the oil level. Add oil if necessary. If the oil is at the
recommended level and the warning horn continues to sound, consult your dealer.
Engine speed will be limited to 2000 RPM, however you should not continue to run
engine.

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
20° 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.
