Abstract: A marine propulsion system having a steering axis that allows pivoting of propellers along a first vertical axis directly beneath a gear box located inside the hull of a boat. A lower gear box can be placed within a vented or non-vented tunnel eliminating the need for a rudder and providing directional control of the boat by the orientation of the lower gear box. Surface piercing propellers and/or counter-rotating propellers may be used with the propellers pivoted around the vertical axis of the gear box. The offset steering axis allows pivoting around the first vertical axis wherein a secondary axis is moved with minimal drag providing superior maneuverability at both high and low speeds.

Abstract: An improvement to a conventional surfboard includes an impeller and an electric motor contained primarily within the body of the surfboard, whereby performance of the surfboard is substantially unaffected by the presence of the impeller and the electric motor. The electric motor is operatively connected to the impeller for providing a forward thrust of the surfboard. The improvement to the conventional surfboard also includes a throttle for selective control of the electric motor for operating the impeller to provide a forward thrust of the surfboard, the throttle being configured for use by a surfer lying in a prone position on the smooth top surface of the body of the surfboard. An extent of the surfer's energy that otherwise would be expended during paddling can be preserved for riding waves by using the impeller to provide the forward thrust during paddling.

Abstract: A ship has a water flow forming path (3) formed in a bottom (2), and a propeller (6) disposed in the path (3) and a rudder (8) on a rear side of the propeller (6). A movable side of the rudder (8) faces toward a bow (1a). As a result of this, thrust increases due to generation of a rapid stream by the propeller (6) in the path (3), the propulsion performance improves and the steering performance improves because the rapid stream in the path (3) acts on the rudder (8). An outboard motor (14) may be provided with a vertical channel (13) in a stern (4) of the boat. Replacement can be made through the vertical channel (13). As the propeller (6) of the outboard motor (14) is recessed, it is possible to pull the boat onto the beach while leaving the outboard motor (14) as it is.
