Propulsion system for boats

In an improved propulsion system for boats, the improvement comprising:

• a first propulsion system including a first fluid accelerating rotor with said first fluid accelerating rotor operating with gas and water supplied to forward portions of said first fluid accelerating rotor when the boat is traveling forward at high speed, an elevation of a lower portion of said first fluid accelerating rotor proximal an elevation of a keel of the boat, and which further includes a secondary inlet fluid supply means to supply gas to the first fluid accelerating rotor when the boat is traveling forward at high speed and liquid to the first fluid accelerating rotor when the boat is traveling in reverse and wherein the secondary inlet gas supply means includes a step that creates a waterline that separates the gas and the liquid when the boat is traveling forward at high speed.

The improved propulsion system of clam 19 wherein the reversing mechanism includes a reversing bucket element.
