    New Top SPEED!

    I love these threads.

    Air HOT
    Water HOT
    humidity HIGH

    RPMs 7120, getting better..... pulled .5 MM out if the trailing edge

    78.1

    1200 grate, trim tabs, R&D plate.

    still have to do a little head work

    And you went 78.1 at 7120..
    Mine is a 15/27 setback, and it goes 79-80 at 7250.
    Those damn impeller numbers are meaningless when you go from one (bender) to another..

    It's been that way for years...a 15/25 Impros may be a 14/24 at Island. This is an Island prop and Carl did a great job with it, now I am tweeking it, in half degrees. With an 800 grate we should be doing 79mph. A few more things we should cross the 80 barrier with relative ease. Very powerful ski even with efi.
