Abstract
A propeller blade device used in environments where a propeller system is subjected to blade erosion and wear and may also be subjected to an axial force from water. The propeller blade includes a blade tip mounted on its outer end using a mounting device such as nuts and bolts to form a junction there between. The tip may easily be replaced when worn or damaged without removing the blade. The tip is designed to fracture upon impact with an axial force before transmitting the force radially inward to the propeller blade.
