摘要： A cowling for housing an outboard engine. The cowling includes a plurality of walls defining at least in part an engine compartment. An engine compartment inlet, in fluid communication with the engine compartment, is defined at least in part by at least one of the plurality of walls. A hydrophobic mesh member disposed across the inlet is adapted to prevent at least a portion of a water content of an airflow flowing to the engine compartment via the engine compartment inlet from entering the engine compartment. An outboard engine having the cowling is also disclosed.

摘要： 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.
