The trim limit (TL) switch is located on the left side of the gimbal housing. This switch permits only a limited amount of outward trim travel to provide safe control at high speeds and prevent damage to drive unit or trim cylinder due to lost side support of drive unit.
The trim position (TP) sender is installed on the opposite (starboard) side. If not equipped with a trim position gauge, an empty and unmarked housing is installed in place of the TP sender.
The tilt and trim unit allows you to optimize the performance of your boat by adjusting the angle of the engine, which, in turn, adjusts the boat's running surface. The ability to tilt and trim your engine improves boat performance under a wide variety of conditions from smoothing out a rough ride in heavy seas to reducing draft in shallower waters.
