Vehicle Information
Polaris Centurion 500 Snowmobile (1979-1980)
The Polaris Centurion 500, produced in 1979 and 1980, was a high-performance snowmobile renowned for its powerful 500cc liquid-cooled Fuji triple engine. This engine, delivering approximately 95 horsepower, positioned the Centurion at the top of its class for exhilarating power. During these two years, the Centurion 500 was offered as a single, distinct model without multiple trim levels. Between 1979 and 1980, the primary change was a minor revision to the engine, from the EC51PL-01 in 1979 to the EC51PL-02 in 1980. While the core specifications remained consistent, this indicated a refinement rather than a full generational shift. No major mid-cycle generation change occurred within this specific two-year period. A significant evolution for the Centurion engine came in 1981 with its integration into the new Indy chassis. FAQ:
