Quite often I find the threads get galled if they have been seized and then forced to turn so if they don’t break off, I’ll cut them off, drill them out, chase the threads, and make new ones. The cast handle gets removed first before forcing them as it is brittle and will break quite easily.

Mumbles… really nice work
unfortunately few of us have your skills and…tools 🙂
Very nice work indeed. Looks better than factory new.

Mumbles is right, once froze up, the threads usually get galled even worse during heating/rocking/oiling attempts because of the aluminum threads on the clamp screws. Fortunately, the aluminum is easy to drill out….
Do it the way I suggested and all of the threads will survive in undamaged condition and no disassembly needed and no new parts are required.
not everybody can weld and mercury clamps are much stronger.
I agree, Some people make things happen, others wonder what happened & still others don’t know anything happened!
Well, after lots of soaking and drilling holes and soaking again, I gave up. I purchased a good used transom clamp. Problem solved!
