ABSTRACT:
Disclosed herein is a marine propulsion device including a propulsion unit comprising a gearcase including therein a cavity, a propeller shaft extending in the cavity and including a portion having an outer surface with an axially extending flat, and a forwardly open axial bore, a bevel gear rotatably supported in the gearcase for rotation relative to the propeller shaft and including a central bore receiving the portion of the propeller shaft in spaced relation thereto, a drive pinion supported for rotation by the propulsion unit and drivingly engaging the bevel gear, a shift shaft located in the axial bore in the propeller shaft for axial movement relative to the propeller shaft and between a drive position and a neutral position, a roller retained between the flat and the bevel gear and movable between a driving position in driving engagement between the bevel gear and the propeller shaft and a non-driving position free of driving engagement between the bevel gear and the propeller shaft, and a pair of members movable radially through the propeller shaft and operably connecting the shift shaft and the roller for displacing the roller to the driving position in response to movement of the shift shaft to the drive position and for displacing the roller to the non-driving position in response to movement of the shift shaft to the neutral position.
