WARNING
Avoid possible serious injury or death. Adjust outboard to an intermediate 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 outboard is
trimmed extremely in or down and there is a pull on the steering wheel or tiller handle.
In rare circumstances, the owner may decide to limit the trim in. This can be accomplished by purchasing
a stainless steel tilt pin 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.
2. Trimming Out or Up can:
Lift the bow higher out of the water.
Generally increase top speed.
Increase clearance over submerged objects or a shallow bottom.
Increase steering torque or pull to the left at a normal installation height (with the normal right hand
rotation propeller).
In excess can cause boat porpoising (bouncing) or propeller ventilation.
Cause engine overheating if any cooling water intake holes are above the water line.
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, by rotating knob to bring the 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.

MANUAL TILTING
If the outboard cannot be tilted using the power trim/tilt switch, the outboard can be manually tilted.
NOTE: The manual tilt release valve must be tightened before operating the outboard to prevent the outboard from
tilting up during reverse operation.
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.
