Abstract: A mounting bracket arrangement for a boat powered by an outboard motor having an elongate shaft housing, such that very slight increases in the tilt angle of the motor are made possible. My arrangement comprising a transom bracket adapted to be mounted on the transom of a boat, with the transom bracket including a pair of stern brackets mounted in spaced relation on the transom of a boat. The lower portions of the stern brackets each contain a spaced series of trim adjustment holes, with each hole in one of the stern brackets being in alignment with a corresponding hole in the other of the stern brackets. An elongate pin is adapted to extend between any selected, aligned pair of spaced holes in the stern brackets, with a portion of the elongate shaft housing of the outboard motor defining a saddle member designed to contact a portion of the elongate pin at a location inboard of the stern brackets.
