"Burr!"
Its that time of year again. The time when all the docks come out, the boats leave and summer fun can't be extended any longer. I know that with all of these things buzzing around in your head the last thing you want to do is to figure out how to winterize your ski. So to make your headache hurt a little less, here's what needs to be done to winterize a stand up jetski that will be kept INSIDE all winter long.
Note: for skis being kept outside you will want to take more precaution and other steps found elseware.
1: Move your ski outside to an area that the water can be dispersed of.
2: Remove the cover of the ski and make sure you can pull the caps off the plugs if you develop glow plugs.
3:Tip the back end of the jetski up in the air. You can do this by placing boards or other materials underneath the hull to prop it up.
4: Start the craft, and rev the throttle repeatedly until all of the water is removed from the pipes. ( DO NOT KEEP THE ENGINE RUNNING MORE THAN 15 SECONDS WITHOUT A COOLDOWN PERIOD, you will damage it.)
5: Drain all fuel from the gas tank.
6: Start the engine and run in intervals ( less than 15 seconds) until all fuel is out of the carburetor and lines.
7*: If your machine has a waterbox, make sure to pour antifreeze into it, but most standups do not have one and therefore do not require antifreeze.
