Abstract
A propeller for a marine propulsion device configured for use on a boat has a hub extending along a longitudinal axis and a plurality of blades, each blade having a blade root attached to the hub and extending radially outwardly from the longitudinal axis toward a respective blade tip, and each blade having a leading edge, a trailing edge, a blade face, and a blade back. Each blade has a polymer-based blade core. A portion of an outer edge of each blade core has a flange that is stepped inwardly from both the blade face and the blade back of the blade core. Each flange is electroless plated with a metal coating that covers the flange and fills in the steps on the blade face and the blade back of the blade core to provide a desired blade section. A method for manufacturing the propeller is also included.
