ABSTRACT:
A marine outboard drive and more particularly to two embodiments of improved transmission and propeller shaft thrust taking arrangements for the lower unit. In each embodiment, the forward and reverse driving thrusts are transmitted independently to the lower unit housing. In one embodiment, a single thrust flange transmits the thrust from the propeller shaft to both of the thrust bearings and in the other embodiment, the thrust is transmitted to the thrust bearings on opposite sides of the forward, reverse transmission for axially separating the driving thrusts from each other.
