POWER TRIM AND TILT (CONTINUED)
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 repositioning the tilt stop pins into whatever adjustment holes
in the transom brackets are desired.
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 water
line.

POWER TRIM AND TILT (CONTINUED)
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
Push in the tilt support pin (a).
2
Lower outboard to rest on the tilt support pin.
3
Disengage the tilt support pin, by raising the outboard off the support pin and
pulling out the support pin. Lower the outboard.
Manual Tilting
If the outboard cannot be tilted using the power trim/tilt switch, the outboard can
be manually tilted.
4
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.

POWER TRIM AND TILT (CONTINUED)
Auxiliary Tilt Switch
1
This switch can be used to tilt the outboard up or down using the power trim
system.
Shallow Water Operation
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 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.

THROTTLE GRIP FRICTION ADJUSTMENT – TILLER
HANDLE MODELS
1
Throttle Grip Friction Knob – Turn friction knob to set and maintain the throttle
at desired speed. Turn knob towards (a) to tighten friction and move knob
towards (b) to loosen friction.

STEERING FRICTION ADJUSTMENT

Tiller Handle Models
2
Steering Friction Adjustment – Adjust this lever to achieve the desired steering
friction (drag) on the tiller handle. Move lever towards (a) to tighten friction or
move towards (b) to loosen friction.
Note: To maintain proper adjustment, the locknut (c) located on top of the steering
friction lever pivot shaft can be tightened.
Remote Steering Models
3
Steering Friction Adjustment – Adjust this screw to achieve the desired
steering friction (drag) on the steering wheel. Turn screw towards (a) to tighten
friction or turn towards (b) to loosen friction.
Avoid possible serious injury or death from loss of boat control. Maintain
sufficient steering friction to prevent the outboard from steering into a
full turn if the tiller handle or steering wheel is released.
