    What I do is blow air thru the flush port on the back of the ski- this will clear the water out of the manifold and lines and into the waterbox. In the past I work on the skis in the winter so I remove the waterbox so its never a issue. Removing the back rubber hose on the w.box and putting some in that way wouldn't hurt, I have never done it though. Water freezing in there has room to expand, its the enclosed tight spaces like pipes and water passages in the manifold that you have to watch out for.

    Just noticed your in Houston, does it ever freeze down there ?

    Oh, haven't changed my profile yet. In Richmond, VA now. Would NOT have this thread in Houston.


    I haven't winterized them yet (fogging, etc.), that's why I don't want to put in antifreeze if I don't have to. I just have to get rid of some boxes before I make it to that point.

    Doesn't the manifold gravity drain???

    It should but I wouldn't chance it. In a pinch people put a 60w light in the hull or I even heard of a heating blanket to keep thinks warm.
