<p>A stern drive (10) including a gear set and reversing clutch (46) comprises a bevel pinion (62), connectable to an input shaft (48); first and second bevel gears (64,66) that mesh with the bevel pinion on diametrically opposed sides of the bevel pinion and that are coaxial, each of the bevel gears defining a conical clutch face (80); a transverse shaft (68) passing coaxially through the bevel gears, said transverse shaft defining helical splines (74) and a central passage (170) that extends axially form at least one of its ends; and a clutch element (76) disposed on the transverse shaft between the bevel gears in engagement with the helical splines, said clutch element defining at least one internal recess (176), that extends in a radial direction, and said clutch element defining two conical surfaces (78), each of which is complemental to the clutch face one of the bevel gears; characterised in that the reversing clutch (102) includes a selector rod (168), disposed coaxially within the central passage (170) of the transverse shaft and being axially slidable within the central passage; and at least one selector pin (172), extending transversely form the selector rod; at least one slot (174) being defined in the transverse shaft, extending from the central passage to the outside of the shaft and having an orientation that is generally aligned with the helical splines of the shaft, the selector pin extending from the selector rod, through the slot, into the internal recess defined in the clutch element.</p> |
