We have 7 or 8 Mystere's locally and EVERY one has had a rudder casting crack or break. The boats are all about 10-13 years old and all were anodized. We do sail ALOT here, but i want to do EVERYTHING i can do to extend their corrosion resistance and extend their life span.

I even do a fresh water rinse on my boat every time i sail.

Thanks for everyone's input.
