ABSTRACT:
A bevel gear transmission for a marine outboard drive having hydraulically actuated clutches for selectively coupling oppositely rotating bevel gears to a shaft to affect either forward or reverse drive. The bevel gears are each supported on the shaft by thrust bearings and are on the outer sides of the bevel gears and are urged into engagement with the thrust bearings by coil compression springs that also act to release the respective clutches. As a result of this arrangement, a constant lash is maintained between the bevel gears regardless of whether they are transmitting a driving thrust or not.
