ABSTRACT:
The invention contemplates a marine outboard gear assembly, usable in an outboard motor or an inboard-outboard drive, and featuring (a) constant drive of the meshing gears which transfer power to the propeller-shaft axis, and (b) selective spring-clutching direct to the propeller shaft, thereby (c) utilizing the meshing gears for lubricant circulation as long as the engine is operating and whether or not the clutch is engaged and (d) reducing to an absolute minimum the drag and inertial effects operative upon the propeller shaft when the boat is moving in the declutched condition, i.e., propeller windmilling. Also featured is a particular subassembly of gear and clutch parts on the propeller shaft whereby desired axial clearance can be readily pre-adjusted and selected, prior to assembly to the gear case.
