20080242162 - Scuba tank air powered, steady pulling, diver propulsion device uses dual compound pistons attached to dual water thrusters at efficiency where breathing air is supplied to diver without curtailing normal dive time: Scuba tank compressed air can now power a dual piston compound motor driving dual water thrusters of a steady pulling underwater propulsion vehicle. Motor exhaust provides diver breathing air through a demand regulator. Motor efficiency allows continual, powerful diver thrust without curtailing normal tank dive time. Lightweight vehicle can be... Agent: James & Kittikan Smith

20080242164 - Marine engine exhaust system: A marine engine exhaust system is provided. One exemplary embodiment of the system includes first and second manifolds. A first gas is transferred through a first conduit from the first manifold and is isolated from cooling water through at least a portion of the first conduit. A second conduit is... Agent: J. Bennett Mullinax, LLC

20080242163 - Articulated oar system: An oar system is provided that keeps the blade of the oar at approximately 90 degrees to the centerline or keel of a boat throughout the normal power producing stroke. This reduces the lost effort that is expended when operating oars whose blades are fixed to the oar shaft. A... Agent: Zachary T. Wobensmith, Iii
