Shaft block fix
Clearly, what Guidera48 says is correct. One can see the screws through the deck that used to hold this block in place. Since they are still there and the block is loose, the block is most likely wet and/or rotten. Replacing it will require dropping the rudder (not a hard job so long as you are this far). If you do this, replace the 2-1/2" hose and the clamps; for you won't get a better opportunity otherwise.
You might also just thoroughly saturate this block with WEST epoxy and reattach it from where it is. Be sure to mask off the shaft itself (or just lube it) or the epoxy will *sort of* glue the block to the shaft (this could be broken free however). Pay most attention to filling the old screw holes and to the edge grain. Fill the old holes in the 'glass and drill new ones. Use SS screws, like #10 or #12, and attach the epoxied block to the underside of the deck with 5200. This will add stiffness and keep out water.
Eerily enough the setup Dalliance has looks exactly like that of the Raider 33 from Storm Sandy I am currently working on-- right down to the number and placement of hose clamps and the little bronze packing gland. Apparently my Uncle Joe (Raider Yacht) bought as much hardware as he could from Hunter-- taking advantage of the strong family connections, I am sure!
