Boat propeller

Abstract

A boat propeller system, consisting of propeller blades attached to the forwardmost portion of a cylindrical housing extending aftward from the propeller blades for increasing the propulsion of the propeller system.

1 . A self-supporting propeller system, comprising:
 a plurality of propeller blades, wherein each propeller blade has an outermost tip;   a cylindrical propulsion housing having an inside surface and an outside surface, and having an aft edge and a forward edge;   wherein said outermost tips of said plurality of propeller blades are coupled to said aft edge of said cylindrical propulsion housing.   
   
   
       2 . The propeller of  claim 1 , wherein said plurality of propeller blades includes at least three propeller blades. 
   
   
       3 . The propeller of  claim 1 , wherein said plurality of propeller blades includes four propeller blades. 
   
   
       4 . The propeller of  claim 1 , wherein said plurality of propeller blades includes five propeller blades. 
   
   
       5 . The propeller of  claim 1 , wherein said plurality of propeller blades more than five propeller blades. 
   
   
       6 . The propeller of  claim 1 , wherein said plurality of propeller blades are welded to said cylindrical propeller housing. 
   
   
       7 . A self-supporting propeller system, comprising:
 three propeller blades, wherein each propeller blade has an outermost tip;   a cylindrical propulsion housing having an inside surface and an outside surface, and having an aft edge and a forward edge;   wherein said outermost tips of said propeller blades are coupled to said aft edge of said cylindrical propulsion housing.   
   
   
       8 . A self-supporting propeller system, comprising:
 at least four propeller blades, wherein each propeller blade has an outermost tip;   a cylindrical propulsion housing having an inside surface and an outside surface, and having an aft edge and a forward edge;   wherein said outermost tips of said propeller blades are welded to said aft edge of said cylindrical propulsion housing.
