    Question Stx 15f Proper Flushing

    What is the correct way to flush this jet ski? I am reading that you need to have the water off when starting the jetski and water off when turning the ski off? I have always turned the water on first and off last and have had zero problems. How can this damage your engine?

    because lame idiots forget the hose has been turned on and walk away from their ski!! but turning it off last leaves your waterbox full of water this is also asking for trouble in the longterm. get all the water out your ski will last that much longer.

    to be safe, start ski
    water on
    flush
    water off
    blow out water
    stop ski
    make sure you flush for a long time on the 12/15f after salt water ride, around 5 minutes or more, the rings in the exhaust to waterbox need flushing well

    +1 above, see picture below to see what "winterstick" is talking about. These exhaust rings didn't get corroded from not flushing, but from a dealer doing a recall on the fuel tank. When he pulled the engine to change the tank, he didn't properly set the the waterbox all the way on the exhaust pipe.
