ABSTRACT:
A propulsion system for a marine outboard drive includes a seal between adjacent ends of a pair of counter-rotating propellers. The seal inhibits fluid flow through a joint between the propellers, while minimizing frictional contact between the counter-rotating propellers. In at least one embodiment, the seal contacts only one of the propellers.
