Good point on the CL change Dave! The notch would remove several sq. ft. of planning surface, so even IF CG were unchanged, that would still reduce stern lift that helps low speed planning! Might be able to compensate with other stern lifting devices like trim tabs, 4B props and AV plate fins, but then you're back to needing the extra stuff you'd also need with a bracket! Might still be a bit lighter than a bracket, although I could see the sides of that tub being about 1.5" thick with some big knees on motor mount surface to transfer motor loads into the stringers and existing transom! I started reading Dave Gerr's book on Boat Strength but still have a long way to go! Denny
