ABSTRACT:
In an outboard marine drive including a vertically oriented engine, a disk member is attached to a lower end of the crankshaft of the engine, and the upper end of the drive shaft is disposed coaxially with respect to the crankshaft and at a prescribed distance from the disk member so that a direct coupling member and an centrifugal clutch device may be interchangeably installed between them. The disk member is provided with axial holes for either pivotally supporting clutch shoes or fixedly attaching the upper end of the direct coupling member. The lower end of the direct coupling member and the clutch drum of the centrifugal clutch device are provided with an identical coupling arrangement for coupling with an upper end of the drive shaft.
