Remember that the 20' hull was designed for the I-6 Merc, which weighs less than 300 lbs! With their relatively narrow beam, they're quite weight sensitive, but very efficient and so they perform best with small light motors. If you run offshore, they'll start to go airborne at about 20 kts when the seas get up to about 3', so you don't need a lot of power for that sort of use. Something around 115-130 hp is ideal, and I wouldn't recommend anything heavier than about a 150 2-stroke, maybe 375 lbs!
