Abstract: A device for redirecting a portion of the reverse flow of a jet stream created by a watercraft to provide a lateral thrust. The main body of device is fixed to the watercraft and includes two intersecting channels disposed therein. Each channel has a bend that and fluidly connects an inlet to an outlet. The reverse flow enters the respective inlet in a downward and backward direction with respect to main body. The respective inlet and channel of main body bend the reverse flow such that, when the reverse flow exits the outlet, the reverse flow is primarily lateral.

Abstract: An auxiliary appendage attachable to the steerable nozzle of an existing water craft. A first and second rudder blade attach to steerable nozzle. The first rudder blade includes a torsion spring providing a downward torsion force. A detent attached to steerable nozzle prevents rudder blades from hyper-extending in the direction of the downward torsion force. Rudder blades are connected by a deflection bar. Deflection bar is angled towards rudder blades. Rudder blades pivot between a downward position to an upward position based on the forces created thereon from both the torsion spring and the movement of the water over the appendage.

Abstract: A marine engine flushing system for super flushing the cooling system of a marine engine comprising an off-axis inlet port for receiving the flow of fresh water, a rotary distribution cylinder, and a plurality of axial outlet ports for proportionately discharging the flow of fresh water. The rotary distribution cylinder provides enhanced hydrodynamic forces that help break up salt and mineral deposits in a fashion superior to all existing methods.
