    Question Prop questions

    Have a merc 125 on procraft 17ft. Prop is a merc laser 2 with 26 pitch. WOT 5100 rpms at 51 mph. My holeshot is great as long as Co angler is not a huge guy and livewells aren’t full of water . My problem is cavitation at higher rpms. . Since I haven’t ever seen any “ rooster tail “ I can’t help but wonder if the motor too low behind the boat. Any help or advice would be great

    Sounds like your little deep , measure prop to pad ,need start round 3in below,if your deeper than that ,you will notice speed increase,and rpms,, I would think 5400 5500 be good. Keep eye on water pressure
