Jeeze! That's crazy. What's the best way to get the water out of the cooling system then? Run it as dry as you can out of the water, then dump some antifreeze into the head and pipe and run it through?Just be sure to winterize after each ride in case the temps drop suddenly.
I rode late December once back home and then stuck my Seadoo in my heated shop. I planned on winterizing it on the weekend so I figured it was fine for the week.
The temps dropped to -30C by Thursday and I came home to find my Dad had needed my shop, and rather than move my Seadoo off to one side, he rolled it outside and left it.
The engine was fine but the water swelled in the pump and destroyed it. Cost me close to a grand to replace it.
