<p>MARINE OUTDRIVE APPARATUS OF INVENTION A marine outdrive attachable to the transom of a boat having an inboard engine. The marine outdrive includes a support casing securable to the boat's transom and having a ball socket. The ball socket receives the ball of a propeller shaft carrier. A drive shaft connectable to the inboard engine is journalled in the support casing. A propeller shaft is journalled in the propeller shaft carrier. A double universal joint connects the two shafts, with the center of such joint coinciding with the point about which the ball pivots within the socket. Hydraulic steering cylinders are attached to the propeller shaft carrier to swing about a generally vertical steering axis extending through the aforementioned pivot point. A hydraulic trim cylinder extends between the transom and the propeller shaft housing to swing the housing vertically about a horizontal trim axis extending through the aforementioned pivot point.</p> |
