J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Zinc Question

I never did get my zinc bolts to break free. On the head I removed the plate and changed it from the inside and made a new gasket. On the engine block where the hose connects to either side of the zinc, I never did get it out. I will need to pull the engine at some point I think to get it. It was clear I was going to break the whole unit off.
