    2001 Polaris Virage

    I need help problem solving. Ski ran great and i ran gas down to 1/8 tank and 1/2 tank oil. I filled the gas up and oil. Ran for about 5 mins till i got up to full speed and now will only go 5 mphs tops. Only change i had was i used quicksilver 2 cycle oil instead of Polaris 2 cycle oil. Any ideas?

    Welcome

    The problem may have nothing to do with the oil and refueling.

    Is this PWC new to you?

    What maintenance and checks have you done?

    Cylinder compression?

    Fuel injected or carburetor engine?
    Three cylinder?

    Any red lamp or message on the display?

    Was it winterized last year?

    What maintenance has been done since July 4, 2009?

    Check cylinder compression.

    Used Stabil in gas. Its garage kept and have ran two tanks of gas through it this year. Just cleaning and new battery but have had no problem since last year and that was just the spark plugs. I put 2 new ones in there this year. when I have the ski docked it will rev up without hesitation and when it gets in water is when it just wont go over 5 mph on the water

    What engine RPM are you seeing in the water?

    Full engine RPM, but no thrust from the jet pump?

    In water about 2300 rpm. seems like whole system is being held back when its in the water. its getting gas in the carburator too. how many jets are in the carburator that could get clogged. Thats is what its acting like or is the make up of Qucksilver oil different enough to make the ski not fire correctly under load?

    I doubt the Quicksilver oil has anything to do with it.

    Check compression in each cylinder. All spark plugs out, throttle held wide open. All cylinders should be with 5% of each other.

    Check the basics. Correct spark plugs? Spark on all cylinders?

    Is this a two or three cylinder engine?

    Yes correct spark plugs and will have to check the compression 2-cylinder

    On the two cylinder engines, both spark plugs fire together every time, and both spark plug wires must be connected and plugs grounded to the engine for either spark plug to fire.
