Can a snowmobile drive on water?

Snowmobiles don't drive on water so to speak. However they can and do hydroplane on water, and is sometimes done on an oval track cut in the ice. Once they hit the water, if they do not go right down, they must keep the track spinning to propel them across the water. If they loose momentum for any reason, they are going down like a stone. I hope this sheds some light on your questions.
