I think I have an electrolysis problem.... Over the past two seasons I have experienced some severe bottom paint problems specifically around my thru-hull fittings and on the keel. They are circular in shape and appear to "blow-off" the bottom paint. I did change bottom paints from a Woolsey ablaitive paint to a CSC ablaitive paint. However, I am not confident that is the problem. An electrical technician checked out the bonding system and he indicated it was satisfactory. His thoughts were that the paint problems might be caused from the different bottom paints and materials used previously to fill in parts of the keel and around the thru-hull fittings. Any thoughts or similiar instances with other O'Day owners? Any help would be appreciated. Thanks in advance. Pat Hentschell
