A watercraft is provided with a propulsion system having a hydraulic power plant driving a propeller through a transmission. The power to operate hydraulic pumps in the power plant is derived from wave motion by buoyant members connected to the power plant by outrigger arms. Undulation of the waves is converted to fluid pressure by the vertical movement of the buoyant members reciprocating pistons in the hydraulic pumps. Pressurized fluid is applied to a fluid motor driving the transmission. A steering assembly is operatively associated with one of the buoyant members.
