Several years ago a guy named Baysailor Bill in the Providence RI area got on the forum and talked about a 1973 O'Day 23 that he was trying to fix up. Bill is no stranger when it comes to fixing boats, or any boat for that fact. He does excellent work.
This boat had the same cast iron keel issues that you guys are now experiencing and he did a lot of swearing while he was trying to free up his centerboard.
He built a long beam out of 2x6s, lags, and Gorilla Glue to support the bow of the boat in order to get his trailer out from under the hull to be able to work on the keel in his yard.
That done, he worked at trying to remove the centerboard and wound up breaking it in two trying to get it out of the keel slot.
Bill used a special paint called "Rust Bullet". He explains what he did in an email that he sent to me that I am posting here. I'm sure Bill won't mind if I share it and some pics of his boat.
Hi Joe,
The 23 was a good project and I really miss the simplicity of that boat. I would say in hind sight, removing the keel and having it professionally sand blasted would have been the easier way to go, but I did everything with the keel on the boat. After removing the swing keel I used an air-chisel to clean all of the rust from the keel. After cleaning the metal I used a multistage treatment from RUST-BULLET to clean, prepare and prime the keel. Make sure to follow the instructions to the letter and apply fresh “Ablative” Bottom Paint every season to keep the barnacles from eating into the metal and starting the rust all over again. I talked to the man who bought the boat, he keeps it moored on Long Island all season. As of the end of last season, the keel is holding up perfectly.
The Web Site Address for Rust Bullet is:

I will dig out some pictures and re-write a blog on the site to help out some of the guys.
Happy Sailing ans I hope to see you on the bay this season,
Bill
I had some pics of Bill's boat sitting on a slip but they're nowhere to be found right now. He had a Blog which was chuck full of pics of the boats that he restored several years ago and he must have discontinued it.
That O'Day 23 came out looking beautiful when he got through with it. Of course, he had to build a new centerboard for it but he didn't stop there. He built a new classic style forward hatch for it as well.
He later sold the boat and I think the guy who owns it now is located somewhere on the Jersey Coast. The new owner is very happy with the boat.
