The molded body includes a rigid skin forming the shell defining an enclosed cavity in which there is provided an expanded closed-cell foam core of water-buoyant material. The skis are constructed as pontoons of similar construction to the body, and the whole snowmobile can float with a portion thereof out of the water so as to support a rider clear of the water in the event the snowmobile falls through ice.
