Peter-Currently yes. I am pretty confident that, with the excess power managed properly, those motors will be reving pretty low and be as efficient as possible (can't use the word efficient and merc 225 carbed 2 stroke in the same sentence). The weight is less of a concern knowing that 445lbsX2 motors is not really out of line. I see the new SC25's with 225 optis in their ads all the time. I will be playing with those jack plate heights to see the best spot for running. I have been watching your adjustment process with motor height variation. The motors may get new 200hp decals
