Today Is the first day I've been able to get out on Lake Michigan this year. These numbers are with 13 1/4 X 15 Stiletto Advantage prop on a 2014 E-TEC 90, up three holes on a 1984 Montauk 17 with 22 gallons of gas under the RPS and two batteries in the console. I weigh 220lbs. I have a T top on this boat and believe it probably reduces speeds a couple mph above 3000RPM. It was too rough to go much faster today though I did open it up once and viewing numbers was "jiggly" but I think I hit 5100 rpm at 39mph. Seems my most economical speed is 20.9 mph at 3000 rpm.
RPM. MPH. GPH. MPG. RANGE
70 3.0 .1 30. 660
1000 4.6 .2 23 506
2000 8.6 1.4 6.1428. 135.14
3000 20.9 2.7 7.74. 170.28
3200 22.4 3.2 7.0. 154
3500. 25.7 3.9. 6.58. 144.76

I went out today and there wasn't much wind so Lake Michigan was pretty calm. I edited the previous post to show my wide open performance numbers. The correct range should be 114.4 miles.
