Yes Dave high time!
Check along the bottom of the keel with a magnet. If the magnet does not drop off all the way along then I would suspect a drilled cast iron keel and you simply have to exert enough pressure on a long tommy bar on the heads inside, however if they are nuts inside I bet you will find the magnet falls off at regular intervals.
Scrape away the paint and you will probably find a wooden plug banged in on top of a load of old grease. Scrape that away to reveal the head of the keel bolt!
Back inside and start thumping with a brass drift and a club hammer!
Check the boat is not sitting on the keel bolt before starting to knock them out... I have been caught that way.
With an iron keel refit mild steel galvanised bolts, coated in epoxy as well if you like, maybe greased then sealed back in with boat mastic, Sikaflex or the like!
Never be tempted to use any grade of stainless under the water, recipe for disaster!
Hope this helps,
John
