Abstract
A marine drive (1) for a boat (3) includes a construction wherein a propeller supporting bearing device (29, 40) is disposed in a recess (28, 39) inside the propeller hub (23, 22). A bearing carrier (24, 37) is concentrically associated with a propeller shaft (20, 18). The carrier is provided with a rearwardly extending nose portion (27, 38) which is telescoped within the forwardly facing recess in an adjacent rearward propeller hub. The propeller shaft is journalled in the bearing device which is disposed between the carrier and the shaft and within the recess. In one aspect of the invention, the carrier is prevented from rotating about the shaft axis (17). In another aspect, a sealing device (26) is disposed between the propeller shaft and the rear end portion (8a) of an adjacent supporting gear case (8). In the embodiment disclosed, dual propellers and dual bearing carriers are utilized, with bearing carrier noses disposed in recesses in both propeller hubs.
