ABSTRACT:
A power transfer device for an inboard/outboard motor which includes a propeller unit mounted on the hull of a vessel, the propeller unit including an input shaft for drive connection to an output shaft of the inboard/outboard motor, an intermediate shaft connected to a propeller shaft, a hydraulic clutch provided on the input shaft to establish a drive power train between the input shaft and intermediate shaft when it has been engaged and to disconnect the input shaft from the intermediate shaft when it has been disengaged, and a changeover mechanism of the gear selection type disposed between the input shaft and intermediate shaft for switching over the drive power train from a forward drive to a backward drive or vice versa. The power transfer device is provided with a hydraulic control apparatus for operating the changeover mechanism in shifting operation to switch over the drive power train from the forward drive to the backward drive or vice versa in a condition where the hydraulic clutch is maintained in its disengaged condition and for engaging the hydraulic clutch after the drive power train has been switched over from the forward drive to the backward drive or vice versa.
