    摘要: A propeller and exhaust system for an outboard motor wherein performance is improved by permitting the flow of some exhaust gases in proximity to the propeller blades at low speeds so as to aerate this area and so as to preclude the aeration when the speed of the propeller exceeds a predetermined speed for improving thrust.

    摘要: An improved thrust bearing arrangement for locating the drive shaft of a marine drive. In accordance with the invention, the thrust bearing is fixedly supported between the lower unit and a supporting housing and the location of the drive shaft is controlled by a shim that is positioned between a flange on the drive shaft and the inner race of the thrust bearing.
