    2006 FX HO porpoising at 26 mph

    Ran the ski today on the lake after last weeks overheating debacle and I had no problem overheating. We were cruising around the lake around 25 mph and everything was good. My daughter and I changed riding positions on the ski and the ski started porpoising bad a around 26 mph. We tried adjusting the trim up and down and may have had a minor affect at full trim down (i.e. pushing nose down) but I was somewhat disappointed at how it handled with two people especially we me on the back. We also tried riding a little faster (i.e. 30 mph) but it seemed to get worse. The ski did not porpoise last week with just myself on the ski.

    Once again, any suggestions would be greatly appreciated.

    i think you owe me a thanks on the overheat issue,
    now seriously, take that cheap ass plate that comes with the ho and install a sho plate, your problem will be solve. also a riva grate will help a lot, i've got two of those 07/06 that now have been converted into a sho and the 06 had the same problem as yours.

    Yes your right......I OWE YOU ACCOLADES ON THE OVERHEATING ISSUE......THANK A MILLION....Now for that cheap ass ride plate you sold me........LOL

    So, what plate should I get a stock SHO ride plate or aftermarket. What will the ride plate get me? I really need the porpoising gone. This thing beat me to death yesterday.

    Thanks again,

    lol. that's funny.
    anyways, the 07 i've got did not had any porpoising at all and the 06 was a killing machine , just like yours, i start with the intake grate and by accident i drop in a stock oem sho plate, the plate was the kill on the porpoising deal. don't know why two identical skis will ride way different, or why the sho plate cure the 06 porpoising . cant explain.

    It's OK, just trying to bust your chops. I really appreciate all your help. I would have had a stock ride plate whether I used yours clean ride plate or my corroded ride plate. Does seem strange that the 07 doesn't exhibit the same problem with the same components. Like I said, it has something to do with weight distribution. Let me ask this question. Should the shoe stick down below the ride plate? I don't think it does on my 2000 SUV but I realize it is a different.
