So who has actually removed and replaced the bulkheads & chain-plates on their O' Day 25? I have Don Casey's book and have looked at the West System page on swapping out bulkheads, and done numerous searches on the interwebs but, I want to know how it is done on my boat, a 1977 era. Removal information would be extremely helpful if anyone has first hand experience doing it. I have read in various places that they are screwed and glassed in. I have not had a chance to dig in to it on my boat as of yet, mostly because of time and the fact that it is about 15 degrees today. Anyway, as I said, I would really appreciate some first hand knowledge to help get me started in the right place.
