    Ok, wife says its got to go......Ski is gone and I have several parts to get rid of....

    Have no idea, someone just tell me what they think its worth.

    Stock Prop
    Stock Sponsons
    Stock Ride Plate
    Stock Air Box and Filter

    AND 1 RAM AIR Seat
    Are you interested in the RAM AIR SEAT ?

    I have $320-$350 worth of material in it

    $150-Rear Seat
    $80-Fiberglass and Material
    $60-Tubing and Couplers
    $30 Flo-Rite Material
    and a crap load of labor.....

    Taking offers, just sitting here on shelf

    Filter fits in seat, Flo-Rite Material Stops Water
    Strong enough I still superman'd on it.
    Used a Bumper Style Fiberglass to allow some flex.
    Fits Like a Glove ****AND NOT OJ's

    Thats pretty damn slick, I think someone might give you 400.00 for the seat though and probably no more if that but its nice.

    RPM Increase

    I never ran with tiny tack or true rpm tach, but without I would only pull 2 bars sometimes 3 if temp was cool. With Seat I pulled 5 bars all the time....I think each bar is 160 RPM

    More importantly the mid range response was much better.

    MPH was up 2+ with seat in the heat.

    Without seat 66-67's GPS
    With seat 69's GPS

    My highest GPS was using my brothers Etec, full tank fuel, non superman, just raked back using my legs to direct more air into ports and no florites.
    69.8 mph.

    The day I sold the SKI I made a few last runs and got consisten 65.7 GPS without and 69.1 with.

    So I know the seat made huge difference.

    I was told my ski ran a 71.2 GPS using my seat on Lake Lanier the weekend after I sold it. I was not there or could verify, but the guy who sold me my boat said they took the ski out with friend that bought ski and GPS it at over 70. Who knows oh well.........

    I did not want to sell seat as I was looking at another 15 with blown engine to build a turbo ski.

    But now have to sell and just start from scratch as I am leaning towards a GPRXP if I am going to proceed.
