    Default Filed my impeller, 80 Yamaha jet

    File parallel to the bench it was setting on.
    3 edges filed, one yet to do.
    Read it will improve efficiency & reduce cavitation .

    Follow these for tuning jet unit impeller. It makes a huge difference when it done right.

    After reading this again, I think I filed it the right way.
    I did go back & round the shoulders
