Hi Mike
We have just purchased a Freedom 255 which has the 257 hull, love the boat, the 257 will be great in Georgean Bay. We have the new 300 hp 4.2L engine and the boat is rated for 350 HP, she will easily take that extra weight and HP. If you are looking at Desmasdons as the supplier, they are top shelf, we have bought two Grady's from them. Send me a personal if you like.
