I remember my Cousin towing me behind an Evinrude Skimmer 400, in like 1976 77, Northern wisconsin Christmas break. it was so cold the plastic red sled cracked apart, and noticed I was riding on my Snowmobile Suit. -15-18 F below in the morning, single digits below zero for a high. The only way to start the other snowmobile was to warm the carburetor up with a propane torch. What could go wrong? LOL....
