Winterize my jet ski for the cold

I'm a little confused about whats right. This fall when weather started to get cold here I decided ( as I have done with my previous boats) to winterize my kawasaki jet ski. While I was searching for the best price around town I was surprised to learn that unlike boats different dealers have completely different ways of dealing with the cold. One dealer that all they've been doing throughout the years is running the motors dry until all the water is expelled. The next dealer said that I should take some part of the plumbing off and blow pressurized water through what I presume are the lines. And the last dealer said that I should run antifreeze through seawater lines to get the water out. Of course all of them Fogged the engines. What do you think is right? are all the methods okay?
Thanks Bobby

Dear Bobby,
In the cold you want to get out all the water as it can freeze and expand and possibly crack your cylinders and exhaust manifold. You want to run Jet Ski engine as it will get water out of exhaust system. You can blow compressed air through the water line that goes to the jet pump (blow air both ways). Or you can add antifreeze to the cooling lines filling up the waterjackets. Also add some fuel stabilizer to the fuel or plan on draining the gas before you go riding again and add fresh gas (You can take the old fuel and put it your car). You should add an ounce of oil in each cylinder, Charge the battery from time to time during winter.
