    poor performance

    I am not sure what is going on! I have had my 2001 slh since beginning of summer and it has run fine until last weekend. It will start and idle fine, when i give it gas it will go about 15-20 and when i give it more gas it tries to die. I bought new plugs for it and it does the same thing. I hooked it up to the hose and it runs fine. What my problem!!???

    Remove the cover on the drivehaft,take out plugs and twist the driveshaft,Do you heard grinding or noise or binding? remove or look in the grate from bottom of hull,see anything? Also check the fuel system...Do a search..alot is post on that.

    took pump apart found nothing, took the carb apart cleaned,
    i think i have bad gas. any suggestions on how to drain gas? I have about 3/4 tank in it, 9-10 gallons! that sucks! $30 or so wasted if its bad! or how could i test it in the tank? i checked the water seperator and it had little water but not much. This is so frustrating!

    Proper disposal of old or bad gasoline?

    There's a good question;
    How does one dispose of contaminated fuel (water, old gas, unwanted pre-mix, etc) without being an environmental dufus about it?
    What do Green Hulk folks do?

    As for getting the old gas out of the PWC tank, a gasoline siphon through the filler neck will get most of it, especially if you can get the siphon inlet into the very lowest spot inside the tank.
    You can buy a gas siphon kit at almost any auto supply store, or use some tubing with a little suction to get it started. Just don't inhale or swallow any gas!

    what will happen if i try to run it and there is still possibly water in the tank? other than poor performance, will it mess up my engine? the reason i ask is because it wont run bad unless it is under a load in the lake, so i was going to try it today and see if cleaning the carbs/draining the seperator worked or if i the whole tank is contaminated with water.

    Are there any warnings on the MFD?

    If there is only a small amount of water in the tank, the separator will catch it.

    Have you done a compression test?

    Can you post pictures of the plugs?

    pres, here's what I would do if it were my ski and I know there's some water in the system.

    Check crank index as water doesn't compress.
    If enough water entered into a cylinder you will bend a rod, crack a piston and/or spin the crank out of phase.
    Check compression.
    Empty the fuel tank and clear the lines of all contaminated fuel.
    Replace any kinked or worn fuel lines.
    Disassemble and rebuild fuel pump or replace.
    Check for any other restrictions in the fuel system.
    Check the electrical box for water and test stator while there.
    Good Luck and let us know how you make out.
