But you guys are right...in the end, the fuel burn difference really doesn't matter...unless you have gassers on a planing hull.
Thanks Al, it does go up quickly from there. I haven't crunched the numbers but as soon as you try to go above 8 kts, over 1600 rpm, the gph seems to go through the roof.
