Abstract: An adjustable outboard transom which is characterized by a pair of transom mount brackets bolted in spaced relationship to the transom and a pair of slotted motor mount brackets which support an outboard motor and cooperate with the transom mount brackets in sliding relationship, respectively, for vertical adjustment of the outboard motor. A shaft with a nut on one end rotatably connects the transom mount brackets and a pawl and rachet mechanism cooperates with the shaft to facilitate incremental shaft rotation by applying a wrench to the nut. A pair of cable mounts secured to the motor mount brackets anchor each end of a cable which is wound around the shaft and bolts extend from the cable mounts through the slots in the transom mount brackets, respectively. Raising and lowering of the motor mount brackets and the outboard motor is facilitated by rotation of the shaft to selectively wind and unwind the cable on the shaft.
