Never a Gori prop again!

The first propeller, Radice had no signs of galvanic corrosion after 14 mnths at the exact same mooring place at my dock, and no canges of other boats around, electric cables or whatsoever.No shorepower, no nothing hooked up that could add current.The shaft-tip anode was still there when the boat went up for the change.The original Gori anode is almost at the exact same place, but perhaps 1/4 size of the old one, protecting double the mass of different alloys. Ball-shaped anodes which you mount around the shaft have several disadvantages and risks:They encrease drag, they create cavitation, (air bubles) that goes straight into the propeller, they create unballance of the prop shaft as they get eaten up, and finally they have a tendancy of getting loose, slide down the shaft and block the water through the cutlass bearing. As noted there is no room for an extra anode in front of the propeller, so unless one does not want to lift the boat every three mnths, a different brand seems to be the solution.
