With the 175 hp suzie the boat does about 42 MPH with a full load at WOT. I can go all day and barely burn fuel. Not sure exactly what the numbers are but it's minimal. I spent all day offshore running and only burned a half a tank (30 gallons or so).
Evidently Pioneer is building a 22ft sportfish...so you may want to wait.
