ABSTRACT:
A boat propeller wherein the blades are easily removable from the propeller hub on an individual basis to permit quick replacement for repair and/or for substituting blades of different pitch comprising a hub adapted to fit over and attach to a drive shaft; a plurality of removable blades positioned around said hub and extending radially therefrom, each of said blades comprising a water engaging blade portion and a rigid tang extending from the base and of such blade portion; a plurality of blade engaging sockets disposed on and around said hub, said sockets adapted to mate with and receive the tang of said blades; and preferably a cover plate adapted to fit over the portion of said tang within said socket, tang, cover plate each being provided with a plurality of aligned bolt holes; and a plurality of bolts extending through said aligned holes and holding each assembly thereof together. Further modifications include a blade assembly for use wherein less force will be exerted, e.g. an electric trolling motor drive, wherein the bolts may be substituted by a spring-loaded button retainer for the blade and the provision of folding blades to permit easier and safer storage of the propeller when off the drive shaft.
