A marine drive unit in combination with a coupling (6) between the engine (4) and the propeller drive unit (2). The unit has a divided flywheel cover (20), the proximal portion (22) of which is joined to the engine and has an axially extending section (25) with a connecting portion (38), which has, as seen in the drawing, an inner profile which is upwardly tapered both longitudinally and transversely to the drive unit. A primary shaft (16) is joined via drive knuckles (15) to the propeller drive unit (2) and is borne in a bearing (28) mounted in a seat (27) in a first end of a bearing holder (26). The primary shaft (16) engages a flywheel (19). The other end of the bearing holder (26) is joined to the distal portion (24) of the flywheel cover. The distal portion (24) has a supporting portion (31) with an exterior profile complementary to the interior profile of the connecting portion (38). The proximal portion (22) of the flywheel cover can be anchored to its distal portion (24) via a screw (42) and the bearing holder (26) has a rubber element (32) welded to its outside, the rubber element being mounted in abutment with a shoulder (36) in a passage (12) in a bushing elements (10) fixed in the boat transom (9).
