Abstract
A device for propelling a personal watercraft comprising a base having an inner channel and an outer channel. A fin is disposed substantially adjacent to the base and is rotatable relative to the base. The fin has an inner protrusion adapted to moveably engage the inner channel, and an outer protrusion adapted to moveably engage the outer channel. A yoke is disposed substantially adjacent to base and adapted to engage the inner protrusion. When a force is applied to the yoke along a first vector, the inner and outer protrusions move in reciprocal directions causing the fin to rotate.
