A watercraft having a propulsion mechanism extending through an opening in the bottom of the watercraft having a propulsion mechanism adapted to be inserted in an opening in the bottom of a watercraft comprising a pair of pedals each coupled to a flexible fin extending below the water line, the pair of fins oscillate through an arcuate path on a horizontal axis to propel the watercraft. The horizontal axis is preferably continuously rotatable in either direction through 360° on a vertical axis disposed at a substantially right angle to the longitudinal axis of the watercraft to propel the watercraft in any direction.
