I've read into the process of replacing the keel lifting line before taking on the task and correct me if I'm wrong but haven't found anyone mention this method of removing a stuck keel so thought it would be worth sharing.
Having lifted the boat, undone the bolt the keel would not budge no later how much 3 of us pushed, pulled, wiggled. In the end I went inside the boat and looking down through the bolt hole could see the flat top of the metal housing, I positioned a piece of bar on here and tapped it down with a lump hammer. Obviously being super careful of the threaded bolt hole and everything else around it.
It was very easy and a controlled method, gradually knocking it out with friends catching it as it came free.
It worked great so may just help you too. Happy to stand corrected if there are pitfuls in this process which I have overlooked.
