Abstract
An gear case assembly for a watercraft propulsion system has a gear case housing, a driveshaft with a partially threaded bore defined in an end thereof, and a propeller shaft. The propeller shaft and the driveshaft are angled relative to each other. A bevel gear is mounted to the propeller shaft. A pinion mounted to the end of the driveshaft. The pinion meshes with the bevel gear. The pinion defines a central aperture. A fastener is disposed at least in part in the central aperture of the pinion. The fastener fastens the pinion to the end of the driveshaft. The fastener has a head and a shank. The shank is at least partially threaded. The shank extends into the bore of the driveshaft. An outboard motor having the gear case assembly is also disclosed.
