Ski-Doo Blizzard 645 Snowmobile (1972-1973)

The Ski-Doo Blizzard 645, produced during the 1972 and 1973 model years, was a high-performance snowmobile designed for racing. It featured a new engine and chassis design upon its introduction. Equipped with a 645cc triple-cylinder Rotax engine, this model was known for its astounding performance. The 1972 model year represented a significant redesign, introducing a new 15-inch chassis, an engine mounted low and forward, an aluminum chain case, and a hydraulic brake system. It featured a distinctive "Coffin style" hood. For 1973, the 645cc engine remained largely unchanged, but the Blizzard line adopted a "wedge style hood" and incorporated orange into its color scheme, following the acquisition of Moto-Ski. The 645 and 797 models retained a lightened version of the 1972 chassis, with potential updates to HD carburetors and HP clutches. Q: How can I ensure parts fit my Blizzard 645?
