Abstract

PURPOSE: To protect a marine propeller of aluminium alloy from corrosion, by providing an annular member of aluminium alloy on the rear end face of a propeller boss.
CONSTITUTION: The annular member 2 made of an aluminium alloy, whose spontaneous electrode potential in the sea water is lower than that of the aluminium alloy of the marine propeller, is provided on the rear end face of the propeller boss 1. The marine propeller has a lower weight and a better machinability than a conventional marine propeller of copper alloy. Such maintenance and servicing of the present propeller as replacement are easy. Furthermore, the propeller has a sufficient reliability.
