    When you pull 2mm of trailing edge on a 15/20?

    When you pull 2mm of the trailing edge off an 15/20 impeller, what is the new pitch 15/19 or 15/18, I just want to learn.
    Thanks

    you would have to change the entire length of the impeller blades (front to back) to change the pitch.

    Just tweaking the trailing edge does nothing but dial in RPM's

    jerry Im picking up my reduction nozzle tommorrow and was curious if the ski benefits more from the changes in RPM from a repitch or changing rings, or is it the same thing as long as the RPMS are there.

    I have found the magic combo to be an 81mm ring and to pitch accordingly for that ring.

    is it necessary to pitch and tweak during seasonal and temperature changes to maintain "dialed in" status once you're "dialed in?"

    Yes, but if you have the nozzle with the different rings all you have to do is change rings.
