Every boat is different so I'll ask anyway. I bought a 2005 X19 Tournament Series dual console with a VMAX HPDI 175 a couple weeks ago. It came with a Powertech 23 pitch 4 blade prop. With a half tank of gas, empty livewells, a light gear load, and me and my buddy (230 pounds each) I am consistently getting 60 point something GPS @5200 RPM. All I can turn is 5200. I don't want to run on the rev limiter for 1 MPH but I would like to get 5500 RPMs and whatever speed that gives me. I had my last boat's prop worked by Mark Croxton and won't hesitate to send him another, but which one? Thanks for any help.
