    I have never heard of anybody getting any gains out of an aftermarket water box.

    I have a DG in mine. I have never once got dirty looks, but I have got alot of "What the HELL you got in there?" looks. Everyone with a newer ski always flips out when they hear I only have half the cc's.

    It really comes down to you. The gains in HP are not that much to be honest. I did see a little difference out of the hole and in the mids. But the difference it has on the way i like my ski, so worth it.

    For some reason the 780 seemed to be slightly louder than the 750 with the same water box and they were both annoyingly loud. I sold them on ebay for half of what I paid for them. There is one big difference. They are like 12 pounds lighter or something like that. The top speeds were the same in my experience anyway.

    The only performance gain I've seen is midrange and no top end.

    WOW maybe there just isn't enough back pressure with the aftermarket. Tri oval? You me the DG?
    TDR is up on ebay now.

    TDR “SILENCER” WATERBOX

    The “Silencer” waterbox is made of all aluminum construction and marine grade corrosion resistant alloys. These waterboxes can be installed in the original
    position and utilize the original straps. TDR “Silencer” waterboxes deliver the most horsepower gain for your money. These high quality waterboxes are
    constructed with heavy duty material for longevity and dependability. Installation of a TDR waterbox may require jetting and/or impeller changes due to the
    increase in exhaust flow and horsepower. All TDR waterboxes come in a bright aluminum finish and are available in 2 different styles.
    PRICE $195

    BAFFLED STYLE WATERBOX
    This waterbox is designed for the recreational riderwho wants a power increase with ah deep throaty sound.
    Although the baffle type waterbox is louder than the stock “OEM” waterbox, it is not offensively loud and it is
    the easiest to install. These waterboxes work well on stock, slightly modified, and recreational motors. To
    order, place the letter “B” after the appropriate part#. Example: #02-0013-B Yamaha Waverunner III.
    POWER SPRAY STYLE WATERBOX
    This waterbox is designed for the racer or high performance enthusiast. The TDR “power spray” waterbox
    is completely hollow and has no restrictive baffles, allowing maximum exhaust flow. The “power spray”
    silences the exhaust noise by inducing a series of ultra-fine sprays of water mist. This mist of water applied
    in the proper places quiets the exhasut noise with any restrictions or power loss. WARNING-this waterbox is
    extremely loud and could result in fines for excessive noise. To order, place the letters “PS” after the
    appropriate part number. Example: 02-0058-PS Kaw Ultra 150.

    Yes, DG Tri oval. Same day, same route, same water conditions. (just 1/2 hr later for install) To be fair though, I may have needed to rejet/readjust carbs for the Waterbox? I'm not sure. I just did a swap and test. Did notice a bit better accel as mentioned ^^^^. I find it interesting that GroupK used the DG on their 750 with positive results. Then again, they were using the stock wet pipe I believe. And I had the PSI dry pipe on mine.
