I posted similar question on props page as well but thought might get better info here. I am currently running a 2019 721 pro xp with a 2019 250hp Mercury pro xs four stroke and 12 inch atlas jackplate. Getting about 75 mph at 6000 rpm heavily loaded with a 25 pitch fury 4 . I am happy with performance but like everyone else always looking for something better as well as needing a backup prop. I currently own a 24 pitch Croxton razor xl which I previously ran on a Yamaha Sho and I am interested in which hub kit I need for this motor and if anyone has experience running the razor xl on this boat/motor combo.
