Hi Craig I'am not sure but I don't think you can Galvanize cast iron. I would go with a filler and some epoxy paint. Then, some anti-fouling on top of that. Bob Honshells wrote:

Is it possible to galvanize the older M17's centerboard? If so, has anyone out there done so?
Would galvanization be preferable to epoxy painting? I imagine epoxy painting and filling would be cheaper and would make faering easier.
Would galvanization be prohibitively expensive?
Would galvanization give complete corrosion resistance?
Thanks!
