Chaser.. I have a 77 MA and when I bought the boat the PO glassed two 2x6's together and cut the sides of the motor well out and put the 2x6's on top of the cut out for transom. The 2x6's went across the transom on the inside for additional support. Glassed the 2x6 to the interior of transom(access through boxes at stern) and glass to existing transom cut out. Makes for an additional 5" or so. Mine was still pretty strurdy, but I redid the boat this past winter and closed the transom in.
Manual or hydraulic jackplates just add more weight to the stern. Especially if you keep the 20" transom.
