Zinc Pad


A mounting device to make zinc replacement easier and to insulate the zinc and current flow from the wooden or painted hull. A mounting can be made by insulating threaded rod with heatshrink to the thickness of the hull and separating the nuts from the hull with non-current carrying washers (plastic, phenolic, etc.). This is needed on wood hulls and metal hulls that need separate systems.
