1975 Mercury Sno-Twister

1975 Mercury Sno-Twister

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.

On Sept 20, 2019, The Top of the Lake Snowmobile Museum was awarded a grant of $12,500 for Operational Support from the State of Michigan Council for Arts and Cultural Affairs (MCACA) and the National Endowment for the Arts (NEA – ART WORKS). The grant was awarded through the MCACA peer review process and was one of 561 applications to compete for MCACA fiscal year 2019 funding. The grant requires a 1:1 match and helped the museum leverage the $12,500 of support from its annual income and the many donations from supporters. In particular the museum has received grants from the Graymont Community Economic Development Fund and the Sault Ste. Marie Tribe of Chippewa Indians. It has also received significant donations from the Antique Snowmobile Club of America, The Midwest Vintage Snowmobile Shows, Inc., many snowmobile clubs, several recreational and snowmobile shows, the museum’s internal $1,000.00 Challenge, and many museum members. The grant funds will be applied to museum operating costs. Applicable costs include internal operations, marketing, travel to shows within the State of Michigan and cost of employees. The MCACA peer review process allows for each grant applicant to be competitively considered by a panel of in-state and out-of-state arts and culture professionals. This ensures the taxpayers, who support this project through legislative appropriations, and all other visitors or residents in Michigan will have access to the highest quality arts and cultural experiences.
