ABSTRACT:
A water craft having a single engine and at least one pump that together cause two propellers to rotate independently. The pump pumps fluid to two valves: a first valve that controls a first propeller and a second valve that controls a second propeller. Both valves have a first position that causes the propellers to be rotated in a first direction, a second position that causes the propellers to be rotated in a second direction, and a third position in which the propellers are not rotated. The water craft is propelled in a first direction when the first and second valves are in the first position. The water craft is propelled in a second direction when the first and second valves are in the second position. The water craft is turned in a first direction when the first valve is in the first position and the second valve is in the second position. The water craft is turned in a second direction when the first valve is in the second position and the second valve is in the first position.
