    Thanks
    the 96 has 90hp too
    the 97 i think has 110

    Remember, dont think of it as HP numbers. My 96SLX was a 60mph boat with mods (barely but did go 60mph). It was the most fun I had on a Polaris. It was light, you could spin fast and turn quick.

    It feels very quick. I was on the SLX780 and someone else was on the SL900 they were almost even. The SL900 pulled a little but the ridder on it was heavier also. After I got the MFD's working the SLX780 I belive was saying 54mph but that was in very choppy water and from what I hear the MFD's MPH don't work well at all. I'm still working out some bugs on the SLX780. It's running rough and missing at idle. I'm sure they both probably need a good tune up and refreshing. I just bought a bunch of tools yesterday to do some testing. Compression, fuel pressure, spark, etc.. I also bought new NGK spark plugs that are going in tomorrow. Still looking for the boots at a reasonable price. I may end up rebuilding all the carbs and fuel pumps just for the hell of it.

    I'm still learning to ride them. I have no problem opening them up full throttle. I learned how to lean into the turns at speed to keep them from flipping. I havn't really done any high speed sharp turns yet. I'm too worried it will dump over. I don't want to get the insides wet. Getting the rear to slide at speed is pretty fun. What do you mean by spin fast? Off idle? What other fun tricks maneuvering can i try? I'm still new to these things. I havn't tried towing anything yet or even riding a second person for that matter.

    How would you describe the handling characteristics of these compared to other ski's? I know that they are light compared to most. They both have rear sponsoons which I believe helps stability. What does the ride plate effect? I'm guessing they are both stock. How would I tell? I think the SLX 780 has after market air filters. Pro something or other. Knowing little about jet skis I have no way of knowing what else may be aftermarket. At least until I learn. I will get pics of everything this weekend.

    Thanks

If I found these parts off of a PRO SLX780 would they fit my SLX to up the power. Are there tripple pipes made for the SL900?

    Thanks

    The numbers are listed in some repair manuals, like Clymer. 650 = 68 HP 750 = 80 HP 780 = 90+ HP
