    Few questions ECU/Prop

    Ok so ive been going back and forth on the props between my skat 15.5/22.5 untouched and my solas 15/22r that is pitched. My first question is can you pitch it past the bottom where it would only sit on the blade if on a flat surface? Next question is when trying both props the 4 blade gets me 85mph at 8700rpm and 15lbs of boost while the 3 blade gives me problems such as bucking and low rpm's everytime the boost gets to about 15 the ski surges. Im trying to pin the problem on the prop not working well rotax 8800 ecu. Anyways it went 78mph at 7900rpm with it surging on the boost around 10-15lbs. What do you guys think also if you have insight as to what could be my issue and can call me my numbers 850-685-7424 any info would really help thanks. names Jason.
