ABSTRACT:
A sensor (43) responds to the operation of a marine transportation system to sense on-plane and off-plane conditions of a boat (21) to operate a trim control (44) to automatically position a trimmable drive (25) for a desired boating operation. The preferred embodiment senses engine speed while an alternative embodiment senses fluid pressure opposing boat movement. The drive (25) is moved to an auto-out position (34) at high speeds and to a trimmed-in position (33) at lower speeds.
