    In the past I have had some trouble starting the ski but it always starts up eventually, it is 20+ years old, anyway until it really warms up I cant run it wide open without it almost dying...have to kinda ease into it.

    After running the ski for 5-10 minutes it works out the issue and accelerates fine. UNTIL the last time I put it in....now when I finally get it started it never seems to warm up and when I take my time and slowly work the RPM's up it never gets up to a speed that matches the RPMs.

    Its as if the water intake is clogged...but it isnt...I took it out of the water and had a good look and its clean all the way through. The only thing difference that I can tell is there seems to be more noise and vibration from the shaft...perhaps there is bad bearing in the shaft?
    If you have not done so in recent times, I suggest removing the jet pump and inspecting the jet pump/impeller bearings.

    Your 1994 model should have the 148mm modular jet pump.

    See my signature links for info info and video on removing the jet pump and checking it.

    what is the service history on this machine?
    Have the carburetors been internally cleaned and rebuilt?
    Has the fuel system been refurbished? New fuel hoses, new fuel filter, inspect inside the fuel tank?

    Check cylinder compression. All spark plugs out, throttle held wide open, strong battery.

    If it truly revs up but doesn't speed up maybe the splines are stripped on the driveshaft or inside the coupler or the impeller. I'm assuming a ski that year wouldn't have a rubber bonded coupler. Either way the pump needs to come off as K447 already suggested.

    I have 2 1995 Polaris SL 650s. One of them is draining my battery everytime. It is making an alarm sound when I'm on it in the water when tipping side to side. One side more than the other. Full of gas and oil. This started the middle of last season. I put it on the lift after use and come back after the next weekend and the battery is dead.

    Brand new batteries this year and came back the next weekend and the battery is dead. Only thing I can come up with is the alarm signal seems like its an anti tipping alarm and it randomly is going off draining the battery. Won't do it when I'm dry docked.

    Ski runs awesome other than having to charge battery before every weekend use. As you know its a big pain to unhook the battery every time.

    Hoping for some assistance in finding this alarm and what I can unhook that won't effect the machine. I've heard it could be a low oil alarm but its full of oil but not sure where that wire is or if would harm the machine to unhook it.
