    Ski is on the water and running STRONG! The Hull has about 160 hours on it. and I just got new rings about 10 hours ago and one cylinder re nicked 2 hours ago. the reeds have about 10 hours on them as well. Ski run Very Strong. I should be going to the mud Bug this year so you can see it there, or take it for a ride if you would like.

    Best speed was 79.5 on a 1200 grate and 87 mm Nozzle with a 14/23 Impros prop at 7280 RPMs

    BEWARE BEWARE......of buying from Flyboy, I bought a ski a few years ago from him that supposedly was rebuilt with new pistons/rings and all compression was good just had some electrical work needed. I got the ski home to find that 2 out of the three pistons weren't even the right size pistons, these pistons were very very small for the cylinders and it was obvious that it was done on purpose. if it wasn't done on purpose then Flyboy has no right working on any motor of any kind.......BEWARE, BEWARE

    I WOULD RIP THIS SKI APART BEFORE EVEN THINKING ABOUT BUYING IT FOR MORE THAN $10.00

    Thanks for screwing me FLYboy

    I have ridden with most of the people on here. You all know what My ski Will do. I have been to the bug, and I have rode with many people. The cylinders have not been put back on yet, and everything is inspectable. I'm not trying to Do an injustice to anyone. Mods Please clean this thread up. I'm only trying to sell my ski that I have owned for the past 6 years.

    Heck if you want I can sell it unassimbled and you can knock a little off the price.

    Ported 1300+ top end

    If you have no takers and are willing to start parting it, I'm interested in the top end. (cyls, pistons, PVs heads) I'm looking for a good ported 1300 or larger top end. PM if interested.
