Abstract

Abstract Boat trim adjusting apparatus generally comprising a bracket of generally U-shaped configuration pivotally mounted on a support frame secured to the rear of the boat. The bracket comprises a lower transversely extending base portion and a pair of arms extending upwardly and outwardly from the base portion and terminating at their upper ends in rearwardly extending wing portions. A rod is mounted on and extends transversely across the arms above the base portion and is adapted to be received in recesses in a pivotable mounting bracket for the engine having releasable locking means for engaging the rod. Suitable power means, such as hydraulic piston and cylinder units, are secured to the rear end portion of the wing portions and to support plates secured to the rear of the boat for selectively pivoting the adjusting bracket relative to the boat. In this manner, the engine mounting bracket is also pivoted to enable the trim of the boat to be adjusted while it is stationary or in motion.
