A human-powered, foot or hand operated paddle propulsion system for a variety of differently sized and configured watercraft. A rigid supporting subframe attaches the system to an end of the watercraft. A spaced-apart terminus is wedged towards a boat seat base. The terminus and subframe cooperatively secure the system within the boat. The subframe has a C-shaped bow plate coupling it to the boat end. The paddle assembly is removably quick-connected to the bow plate. Knobbed, slidably adjustable mounting bolts captivate the subframe upon the bow. The frame comprises a pair of adjustable, telescoping frame beams that enable it to retract or extend. The frame supports an adjustable actuating assembly including foot-operated pedals and optional hand bars for powering the boat. Cabling links the actuating assembly to the drive paddle assembly. Slidable captivation of the activating assembly upon the frame facilitates cable length and tension adjustments. The cabling extends through the frame and around the drive paddle assembly between terminal ends on each foot pedal. The subframe buttresses the drive paddle assembly. The drive paddle assembly controls paddle pitch and sweep. A spring lock may be used to lock a cable guide donut in a selected pitch-controlling position. The lock maintains donut positioning until released.

A human-powered propulsion system for boats, the propulsion system comprising: frame means for mounting the propulsion system upon a boat, said frame means comprising a subframe adapted to be coupled to the bow or stern of the boat and a spaced apart terminus for engaging the boat interior; paddle means mounted to said subframe and normally aimed downwardly toward the water for propelling the boat; foot-driven actuating means for actuating said paddle means, said actuating means comprising a mounting sleeve coaxially, slidably mounted to said frame means that is adapted to be positioned at a user selected location between said subframe and said terminus, a spindle sleeve mounted to said mounting sleeve, and a pair of arms pivotal relative to said spindle sleeve with a foot pedal projecting from each arm; cable means extending from said actuating means through at least a portion of said frame means to said paddle means for operating same; and, adjustably mounted anchor spool means for terminating said cable means.
