Too much trim-out puts the bow of the boat
too high in the water. Performance and econ-

boat is pushing the water and there is more
air drag. Excessive trim-out can also cause
the propeller to ventilate, which reduces per-

poise” (hop in the water), which could throw
the operator and passengers overboard.
