    Prop repitch

    so I had a crack at repitching the prop and i must say great the ski down from 8160-80 to 8080 was informed that keeping your revs atleast 100rpm off your limiter will get the best results...did it the easy seems the the 15/22r prop if you sit it on a bench with the big end on the bench your trailing edges will be 4mm in hieght off the bench to tip of the blade...make them 3mm and your smokin..just bent it with a shifter on the prop removal tool in a vice...i have noticed though with pulling the old 15/22r with 80 hrs on it the trailing edges messured from 6mm to 1cm...all were different...even when pulling the new prop out with only 5 hrs on it the trailing edge blades had bent towards the front off the ski almost 1mm....strange yes I just put it down to wave jumping...

    even though the speed remains at 71.5mph with a full tank and two on the ski ...the gas consumtion has noticeably improved.....
