Mod-V ?
Deep V ?
flat bottom?

My 25hp would get almost twice the fuel mileage on a flat bottom compared to a v-hull. Different hulls have more or less drag. So without knowing hull, impossible for anyone to give you a correct answer. I also highly doubt they ever made a Johnson that got 13.4mpg on any hull.
