ABSTRACT:
Disclosed is a flotation system designed to be incorporated into an existing snowmobile and including a plurality of floats which may be inflated either selectively or automatically. The device is intended to be incorporated into a snowmobile which is used on ice covered bodies of water. Sometimes, during such use, the ice breaks causing the snowmobile to sink and thereby be destroyed. Through the use of the present invention, flotation is provided to maintain the snowmobile in a floating position to allow safe retrieval.
