Running a Legend 211 with a 2012 250 pro xs. Prop is a Turbo 25 pitch Ot-4 that has been B&B. Just upgraded to a 112 Ultrex from a 80lb Fortrex. Lost holeshot and 6mph. I was running 72mph at 5900 at any jackplate setting. Would a diffuser ring and adding dual PVS holes help with holeshot or should I try a different prop.
