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
