This snowmobile has its original 8 horsepower Kohler 4 cycle engine. Also is equipped with a forward/reversing transmission and steel roller-chain track with steel cleats.I purchased this in 1985 from the Arctic Cat dealer in Bozeman MT. With much help from my dad Wayne, we had this driving across the Minnesota snow the same day that we got home with it! Painting and some mechanical restoration followed that spring. We have had this on many vintage rides over the years and is still one of our favorites. It is believed that 369 of these were produced.
