That was Potter's early transom closing system that allowed installation of a bracket without redoing the transom. That's a Hermco bracket so it might have enough flotation to at least offset all that weight.
You're right to be concerned about motor weight, because this boat was designed for the 2-stroke motors made in the early-mid 70's! If this was a CC model, I'd be suspicious that your CG is too far aft, but some of the later SCI Sceptre's seem to be bow heavy, maybe because they used plywood in the decks instead of balsa core, so that configuration might work ok on a SeaCraft Industries model, 1980 or later. 78 is a Potter model, so should have balsa core in the decks. If you do a sea trial on it, I'd trim the motors up as far as possible, retract the trim tabs all the way and see if it has a tendency to porpoise. If it does so easily, that's a sign you need some more weight up front to compensate for that half ton of weight sitting 30" aft of the transom!
