Abstract
A propeller assembly to facilitate the cleaning of aquaculture nets. The propeller assembly has a centrally disposed hub with a plurality of plastic composite blades extending outwardly to a perimeter ring. A plurality of triangular shaped rigid knuckles are coupled to the perimeter ring. A blade spacer is attached to a leading edge of each blade, the knuckle and blade spacer are constructed of a wear resistant non-ferrous material, ferrous material, or combination thereof. In operation, rotation of the blades provides thrust for positioning the knuckles against an aquaculture net, whereby the knuckles remove fouling from the aquaculture net by violently shaking the aquaculture net. The blade spacer positions the propeller assembly a predetermined distance from the aquaculture net to protect the leading edge by distance and/or use of the wear resistant material.
