1975 Mercury Sno-Twister: The 1975 Sno-Twister 340 S/T is powered by a 338cc Kohler two cylinder free-air alternate firing engine. In 1975 two Sno-Twister options were offered: 340 S/T & 440 S/T. The 340 S/T cost was $1,685.00.
The Mercury Sno-Twister was the first Mercury snowmobile made for racing. It was introduced in 1974 with a slogan "Snowmobiles which defy the others" and sold for stock category racing. They introduced it into their race team. It also was made for trail riding comfort & ease of handling.
In 1975, confident of obtaining good results for the season, the company continued with its race team for the stock series. The Sno-Twister swept everything in the stock class but in the modified category it was another story (less than astonishing) because the other companies worked hard to get snowmobiles on the starting line that would be able to take on the Sno- Twister.
Feb. 1976 Stan Hayes won the I-500 in Sault Ste. Marie, MI on a Mercury Sno-Twister for the Mercury Race Team from Fond Du Lac, WI. After this big win, 1976 was the last year of production of the Mercury snowmobiles.
