ABSTRACT:
An assembly for rotatably supporting the propulsion unit of an inboard/outboard marine propulsion system of a watercraft is disclosed. The watercraft includes an engine mounted therein which is drivingly connected to the propulsion unit through a through-hole formed in the transom of the watercraft. The support assembly includes a first bearing arrangement for rotatably supporting the drive from the engine to the propulsion unit and a second, concentrically mounted bearing arrangement for rotatably supporting the propulsion unit relative to the transom. The concentric bearing arrangement permits the propulsion unit to be rotated between above-water and in-water positions while minimizing the length of the propulsion system, thereby conserving space and allowing the propulsion unit to be more compact.
