Why don't you just do it in two pieces? Split right down the middle, like two "Cs" around the post until you can take it out of the water and replace with a one piece block. It looks like removing that bolt will drop the rudder, although I don't know your boat.

Nick....not sure how that would be a factor since fabricating a new block should account for those dimensions. Alternately, why not consider fabricating the replacement halves out of aluminum stock? Except for purist, appearance, shouldn't that do the trick? For now at least?
