Instructions

    • 1

      Maintain the correct amount of oil and gas for the jet ski. Verify that there's an adequate level of both fluids in the engine. Older jet skis that run on 2-stroke engines require the fuel and oil be premixed, while the new 4-stroke engines have separate fuel and oil spots.

    • 2

      Take the jet ski out of storage for the summer early. When stored with fuel in the engine and no fuel stabilizer, add a fuel cleaner and stabilizer before starting it up.

    • 3

      Try starting the engine. Consult a trained technician for proper summarizing. They can drain and dispose of the old fuel and ensure the jet ski is in proper working condition.

    • 4

      Change the engine oil and filter at least once a year. Drain the pump oil and replace it with new oil once a year also.

    • 5

      Add grease to all seals and bearing fittings. Inspect these areas several times to ensure their working properly. Lubricate the parts at least once a year.

    • 6

      Check all the wires, including trim and throttle cables for loose or damaged parts. Replace when necessary.

    • 7

      Clean the exterior, seat, windshield and entire body of the jet ski every time you take it out of the water to prevent corrosion or staining.
