Abstract
A watercraft propulsion device having a plurality of cooperating paddles driven by levers in a sweeping motion while cooperating with a peddle gear and electric motor in order to produce a reciprocating back and forth paddle motion capable of driving the watercraft through water densely populated with obstructive matter such as grass, Lilly pads, logs and other debris with ease. Additionally the pedal gear of the present invention allows for the paddles to be lifted while being brought towards the watercraft and then the paddle is brought downward and away from the vessel to push the device forward. Finally a speed throttle arm is mounted to the device to control the speed at which the paddles reciprocate and to control the direction that force is applied at the stern of the watercraft.
Claims5
