I'm running a Yamaha 15 and get about 7mph, and burn about 1.5 gph wide open. The hull speed of a V20 is approx 7 mph, so that's all you'll get with 15,20, or 25 hp. The only advantage to the higher horsepower is if you're running against a current or heavy wind.
higher hp will help in a head wind and in waves but not against a current.... 7mph top speed against a 7mph current = 0mph
