Abstract

A Marine drive mechanism has a twin-engine distribution transmission for driving a propeller-shaft train (12) supported on bearings (4). The drive mechanism (1) and the transmission (3), which is rigidly connected to it, being fastened to the bottom (6) of the hull. A pressure bearing (23) accommodates and transmits the thrust exerted by the propeller (5) by way of the propeller-shaft train. A coupling (3) engages and disengages the drive mechanism. The drive mechanism and the transmission are individually supported, the drive mechanism by resilient supports (9) and the transmission by resilient supports (14) and resilient bearings (13). The pressure bearing is built into the transmission. The transmission bearings (13) are integrated into a separate post (19) rigidly fastened to the bottom and are attached to the walls (11) of the transmission.
