69-70 most of the time. 71-72 under perfect conditions, temp, light fuel, tail wind, six inch chop. They go to 65 pretty quick, its that other 5 MPH that it needs to wind out for. If you are buying it right its not a bad boat, just depends on what you want to do with it.
I did see 80 once but that was because I forgot to turn the GPS off for the ride home
