    787 help

    I'm looking to get some more power out of my moms 787, I think she has a 96 gtx and I was wondering what were the best mods to wake this motor up? I don't know much about these seadoo's... Im a superjet guy

    Welcome crash. Not many mods will help this engine in this hull. You can put a Skat 17/22 on it. That will help hookup and towing.

    my recommendation would be factory spec II...BUT as soon as you start swapping out stock parts for aftermarket ones then your reliability of the motor drastically goes down...just my .02

    Putting a pipe on a GTX hull is really not adviseable. You can run a Rossier reliably, but you may only get two more mph. If you want a little more punch, and not kill the reliability, I'd put a milled head on it, Fly's, and rejet, and leave as-is with the stock pipe. This will get you about 1.5mph and 30% savings in fuel consumption. You'd have to run 93 octane though.

    Worse? It's not worse, it's just heavy. Pipes were designed for the lighter X-4 hulls. For racing. Piping a GTX with an 800 engine is like trying to make a pig fly...there is just no reason. If you want a fast GTX hull get a 2001-2002 951 engine.
