Abstract
A bearing carrier and ring nut of a marine outboard drive both attach to a lower unit of the drive by rotating them in the same direction. The bearing carrier includes a threaded front end which screws into a threaded aperture within the lower unit. A ring nut locks the bearing carrier in place by screwing into a hole on the rear face of the lower unit. A locking tab washer desirably locks the ring nut in place. Because the threads on the bearing carrier and the ring nut are of the same hand, the ring nut does not loosen the bearing carrier when threaded into the hole of the lower unit rear face.
