I opened the boat up today with me the wife, 3/4 tank of gas and full livewells, full ice chest and all our gear I was running 66. Didn't remember to check RPM's I do know I was a only trimmed less than a 1/4 on the dial. Does that sound about right? I'm a big ol' boy. Lake was almost like glass. I usually tool around between 40 and 50. Not a speed freak but do enjoy going fast on occasion. I do know it will eat wakes from other boats like candy.
