ABSTRACT:
An apparatus for adjusting the position of a boat motor. The apparatus contains a first transom member extending perpendicular from the transom, with the first member having a first longitudinal slot therein; and a second transom member extending perpendicular from the transom, with the second member having a second longitudinal slot therein. The apparatus further includes an upper plate position between the first and second transom member, with the first plate being attached to the first transom member and the second transom member. Also included is a first motor bracket member slidably connected to the first transom bracket and a second motor bracket member slidably connected to the second transom bracket. The apparatus further includes a lower plate position between the first motor bracket member and the second motor bracket member, with the lower plate being attached to the first motor bracket member and the second motor bracket member. A central bolt having a threaded stem is disposed through a smooth bore in the upper plate and a threaded bore in the lower plate. A rotational force applied to the central bolt will move the lower plate. The movement of the lower plate will lower or raise the motor in relation to the boat's transom.
