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:
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.
