With all the wells full and 2-3 adults the boat will run 43-46. I know that a lot of people down your way get concerned with the 150 not being enough power but I can honestly say that is far from the truth. She is no speed demon but get on plan quickly and is plenty fast. Basically you can take the RPM's and subtract 9-10 and that's what your running. Cruise is a little better, at 4200 rpm I will see somewhere around 33-34mph. Boat is clean and well taken care of. Call me if you have any further questions I will be happy to talk with you about it.
