That's good to know, I was preparing for quite a headache trying to remove the wood while preserving the floor. I'm thinking that after I drill out the bungs I'll put it back in with brass button head screws and leave them uncovered so the floor can be removed if necessary, maybe add a second access point behind the bilge area. Very happy that I have a wood shop on site. Now that I've pull her out I can see that I'm leaking bilge water through the shaft strut and through what look like stress cracks where the keel meets the hull at the aft-most point. So plenty of glass work figuring that out and re-bedding/sealing the strut bolts. Three months into owning my first sailboat; I heard the jokes but money/time/effort pit really does exist.
