Finally got out to do some WOT throttle runs yesterday on calm water. I'm hitting 37.1 MPH per the GPS speedometer with a F150XB and a Reliance 14.5X15 prop @ 5900 RPM (trimmed up), and my wife and (3) small children on board. Not bad but I'm was hoping for a just a bit more. I'm thinking about trying a 14.25X17 prop but I'm guessing I'm really not going to get much more out of it since I'm already hitting max RPM.
