    I've got an 89 hydrostream hst that runs on gps 123mph. I was thinking about more engine mods and such,but before I do I was wondering if anyone knows if the boat does anything stupid around 130 or better. I don't really know what the boat capabilities are, and don't want to find out the hard way if you know what I mean. I feel I've done well with what I have but it feels so safe at 120 range I can't beleive it can't do more. well if anyone knows please let me know. Thanks wcougarman

    Please....tell us what you're running for set up. Because I've never seen one of these run over 110 without HUGE amounts of horsepower.
