    The dealer is WRONG! Water collects in the cylinders and will crack the motor.

    Remove the water line from the head at it's highest point. Add pure antifreeze untill it runs out the exhaust(about a pint+/-). The antifreeze will dilute in the cylinder.

    ? Couple of Questions

    How much was your jet ski? How much is a gallon of antifreeze? How much is an hour or so of your time worth? and last How much is the peace of mind knowing that your ski will be ready for the spring?

    Winterization is a lot more than just adding antifreeze...but that is unquestionably the most important step...I see your dealer wanted some work in the spring when your ski wouldn't start...

    Avoid SD dealers and take care of what you can yourself...you will be a lot farther ahead...

    Yes...he's very much wrong! Do as Steach said above. The only engine that is self-draining is the 717 and previous engines. It takes less than 5 minutes to winterize your engine...the dealer is trying to make $$$ off you when they crack.
