Outboard drive transmission system
First Claim
1. A transmission for a marine outboard drive comprising a first driven gear and a corresponding first clutch coupled to a first propulsion shaft, said first clutch arranged to selectively couple said first propulsion shaft to said first driven gear when actuated by an actuator, said actuator connected to an annular member journaled within said first clutch in a manner permitting said first clutch to rotate relative to said annular member.

Abstract
A transmission for a counter-rotational propeller system of a watercraft outboard drive includes an improved clutch coupling which allows relative motion between a clutch and a portion of a clutch actuator, while reducing friction and wear between these components. The coupling includes an annular collar that is captured within an inner bore of the clutch. The ends of the collar are journaled within the bore for relative rotation between the collar and the clutch. Sufficient spacing also is maintained between the collar outer periphery and the inner bore wall to prevent contact between the collar and the clutch. A pin connects the collar to the clutch actuator.

- 23. A transmission for a marine outboard drive comprising a first driven gear and a corresponding first clutch coupled to a first propulsion shaft, said first clutch arranged to selectively couple said first propulsion shaft to said first driven gear when actuated by an actuator, a coupling mechanism coupling said first clutch to said actuator in a manner permitting the first clutch to rotate relative to said actuator, said coupling mechanism including a pin which extends within said first clutch in a direction generally transverse to an axis of said first propulsion shaft, said pin being connected to said actuator, and a collar held within said first clutch, said collar capturing at least a portion of said pin such that said collar rotates with said actuator.
