A human driven water propulsion apparatus includes a propeller and a human powered drive coupled to the propeller for driving the propeller. The propeller and human powered drive are connected to and supported by a chassis. Foot pedals are slidably engaged with the helical drive shafts. The helical drive shafts are connected to the propeller through one-way clutches and a gear train such that the propeller is driven by the helical drive shafts when driven by the pedals. In a watercraft application, the chassis is rotatably mounted for rotation between a first position where the propeller is faced in a forward direction and a second position where the propeller is faced in a rearward direction. In a swimmer application, a seat is attached to the chassis by a seat post and straps secure the seat to a user.
