ABSTRACT:
There is disclosed a water board or surfboard wherein a screw propeller mounted on the underside of the board generates thrust in response to the push-pull action of a hand lever which protrudes from either side of the board. The push-pull action on the lever causes a ratchet-type mechanism to rotate a gear assembly which is connected to the screw propeller shaft.
