FEATURES & CONTROLS
POWER TRIM OPERATION (CONTINUED)
WARNING
Avoid possible serious injury or death. Adjust outboard to an intermedi-
ate trim position as soon as boat is on plane to avoid possible ejection
due to boat spin-out. Do not attempt to turn boat when on plane if out-
board is trimmed extremely in or down and there is a pull on the steering
wheel or tiller handle.
6. In rare circumstances, the owner may decide to limit the trim in. This can be
accomplished by purchasing a stainless steel tilt pin (Part Number
17-49930A1) from your dealer and inserting it in whatever adjustment hole in
the transom brackets is desired. The non-stainless steel shipping bolt should
not be used in this application other than on a temporary basis.
Trimming Out or Up can:
1. Lift the bow higher out of the water.
2. Generally increase top speed.
3. Increase clearance over submerged objects or a shallow bottom.
4. Increase steering torque or pull to the left at a normal installation height (with
the normal right hand rotation propeller).
5. In excess, cause boat “porpoising” (bouncing) or propeller ventilation.
6. Cause engine overheating if any cooling water intake holes are above the
waterline.

TILTING OPERATION
To tilt outboard, shut off the engine and press the trim/tilt switch or auxiliary tilt switch
to the up position. The outboard will tilt up until the switch is released or it reaches its
maximum tilt position.
1
Engage the tilt support lever (a), by rotating knob (b) to bring support lever
upward.
2
Lower outboard to rest on the tilt support lever.
3
Disengage the tilt support lever, by raising the outboard off the support lever
and rotating the lever down. Lower the outboard.

AUXILIARY TILT SWITCH
4
This switch can be used to tilt the outboard up or down using the power trim
system.

MANUAL TILTING
If the outboard cannot be tilted using the power trim/tilt switch, the outboard can
be manually tilted.
1
Turn out the manual tilt release valve 3 turns (counterclockwise). This allows
manual tilting of the outboard. Tilt the outboard to the desired position and
tighten the manual tilt release valve.
Note: The manual tilt release valve must be tightened before operating the
outboard to prevent the outboard from tilting up during reverse operation.

PRE-STARTING CHECK LIST
j
Operator knows safe navigation, boating, and operating procedures.
j
An approved personal flotation device of suitable size for each person aboard
and readily accessible (it is the law).
j
A ring type life buoy or buoyant cushion designed to be thrown to a person in
the water.
j
Know your boats maximum load capacity. Look at the boat capacity plate.
j
Fuel supply OK.
j
Oil supply (oil injection) OK.
j
Arrange passengers and load in the boat so the weight is distributed evenly and
everyone is seated in a proper seat.
j
Tell someone where you are going and when you expect to return.
j
It is illegal to operate a boat while under the influence of alcohol or drugs.
j
Know the waters and area you will be boating; tides, currents, sand bars, rocks,
and other hazards.
j
Make inspection checks listed in the Inspection and Maintenance Schedule.
Refer to Maintenance Section.

OPERATING IN FREEZING TEMPERATURES
When using your outboard or having your outboard moored in freezing or near
freezing temperature, keep the outboard tilted down at all times so the gear case
is submerged. This prevents trapped water in gear case from freezing and causing
possible damage to the water pump and other components.
If there is a chance of ice forming on the water, the outboard should be removed
and drained completely of water. If ice should form at the water level inside the
outboard drive shaft housing, it will block water flow to the engine causing possible
damage.

OPERATING IN SALT WATER OR POLLUTED WATER
We recommend that you flush the internal water passages of your outboard with
fresh water after each use in salt or polluted water. This will prevent a buildup of
deposits from clogging the water passages. Refer to “Flushing The Cooling
System” procedure in the Maintenance Section.
If you keep your boat moored in the water, always tilt the outboard so the gear case
is completely out of water (except in freezing temperature) when not in use.
Wash down the outboard exterior and flush out the exhaust outlet of the propeller
and gear case with fresh water after each use. Each month, spray Mercury
Precision or Quicksilver Corrosion Guard on external metal surfaces (do not spray
on corrosion control anodes as this will reduce the effectiveness of the anodes).
onb7
OPERATING AT HIGH ELEVATIONS
Your engine automatically compensates for high elevation changes. A propeller
with a different pitch may be required to help reduce the normal performance loss
experienced as a result of reduced oxygen in the air. Consult your dealer.

SETTING TRIM ANGLE WHILE RUNNING ENGINE AT
IDLE SPEED
1
Submerging the exhaust relief hole (a) on the outboard can happen on some
boats if you trim the outboard “full-in” while running the engine at idle speed.
This will cause an exhaust restriction, resulting in rough idle, excessive smoke,
and fouled spark plugs. If this condition exists, trim outboard up until exhaust
relief hole is out of the water (b).

OPERATING IN SHALLOW WATER
2
When operating your boat in shallow water, you can tilt the outboard beyond
the maximum trim range to prevent hitting bottom.
a. Reduce engine speed below 2000 RPM.
b. Tilt outboard up. Make sure all the cooling water intake holes stay
submerged at all times.
c. Operate the engine at slow speed only. If engine speed exceeds 2000
RPM, the outboard will automatically return down to the maximum trim
range.
