WARNING
Operating the boat at high speeds with the outboard trimmed
too far under can create excessive bow steer, resulting in the
operator losing control of the boat. Install the trim limit pin in a
position that prevents excessive trim under and operate the
boat in a safe manner.
In rare circumstances, the owner may decide to limit the trim
in. This can be accomplished by repositioning the tilt stop
pins into the desired transom bracket adjustment holes.
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 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, by rotating knob to bring the
support lever upward.
2. Lower outboard to rest on the tilt support lever.
