Gear case assembly for a watercraft propulsion system
First Claim
1. A gear case assembly for a watercraft propulsion system comprising:
- a gear case housing;
a driveshaft extending at least in part into the gear case housing, the driveshaft defining a bore in an end thereof, the bore being at least partially threaded, the bore being coaxial with the driveshaft;
a propeller shaft having a first portion extending into the gear case housing and a second portion extending out of the gear case housing, the propeller shaft and the driveshaft being angled relative to each other;
a bevel gear mounted to the propeller shaft;
a pinion mounted to the end of the driveshaft, the pinion meshing with the bevel gear, the pinion defining a central aperture; and

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.
