    I hit 65 mph on the built in speedometer with my wake pro 215 (same engine as yours I presume).

    Don't Expect a lot out of those Hulls. On stock trim between 66-67 on a Good Day.

    thanks guys on the one i drove, max rpms was 7520 at 61 mph flickering 62, 60.5 on gps phone, sounded low to me so i replaced plugs, checked compression, all even at 120 psi, checked injectors on flow bench and all flowed evenly like a new set would, there is no blow by and almost no oil deposit in air intake boot, i even tried to run with air intake boot disconnected from long pipe running along engine side and oriented the elbow up, still no speed or rpms gain, checked the impeller , has a 14/19a solas in excellent shape with ss wear ring, bearing feel good with no crunch at all,water temp at 89 and air 88, half tank of gas and 190 lbs driver, vts neutral on 1 notch up above neutral makes no difference , what do you guys think it could be to be so slow?
