A propulsion mechanism to propel a watercraft through water comprises paddle bars pivotally attached to a support at a first pivot, the paddle bars having a handle at a first end and a paddled second end. A paddle is pivotally attached to the second end of each paddle bar at a second pivot. When the mechanism is operated through the power stroke, the second pivot end allows the paddle to be supported by the respective paddle bar and to be forcefully driven through the water. When the power stroke is completed, the paddle is permitted to pivot about the second pivot and to disengage the respective paddle bar as the mechanism operates through the return stroke.
