    wowzas...road a Kerry Hibdon/Group K monster today

    Well a friend of mine on the lake has a kerry modified boat. 2003 GP1300R (still has the fuel injection), ported, timing, Group K 1390, along with all the other goodies. He let me ride it and holy shit balls. I now know how some of you guys feel. With a full tank I hit 76.4 pretty easily. He is only turning 7040 rpm, so Kerry is sending him another prop to bring his r's up. Expectations are close to 79 with the new prop and when he gets the rest of it dialed in.

    I just thought I would share my story for the weekend...simply amazing.

    Kerry builds super fast boats ! seen them run in person at Mudbug.

    Thats impressive speed for a full tank !

    There aren't many boats in this "World" running 77+ out of the whole PWC population running Recreational boats

    I know Billy! I still can't beleive I had the chance to ride one of these beast.

    Caution: Riding a Kerry monster even for the shortest period of time is a sure fire way to significantly lighten your wallet in the near future.

    Thats great to hear guys. Glad some of you guys are keeping the fuel injection. I am very interested in the progress of this 1390 EFI.
