Vehicle Information
Ski-Doo Olympique 300 Snowmobile (1966-1978)
The Ski-Doo Olympique 300 series, produced from 1966 to 1978, was a popular entry-level snowmobile known for its lightweight design and ease of use. The "300" designation typically referred to a class rather than an exact 300cc displacement, with engine sizes varying slightly across the years. Initially, models like the Olympique and Super Olympique featured single-cylinder Rotax engines, ranging from 250cc to 300cc, with horsepower between 10.5 hp and 16 hp. Electric start became an option on certain trims by 1968. A significant evolution occurred around 1975, when the series introduced a 294cc twin-cylinder fan-cooled engine, marking a shift from the earlier single-cylinder configurations. This change offered improved performance and often came with electric start as a standard or optional feature, continuing through to the final models in 1978, which also included both single and twin-cylinder options.

Maintenance
| Component | Interval | Details |
| 2-Stroke Engine Oil | Check frequently | 2-stroke engines do not have a traditional oil pan. Check oil reservoir level (injection) before every ride or use recommended pre-mix ratio (e.g., 20:1). |
| Chaincase Oil | Check pre-season and every 50 hours. Change annually or end of season. | Use manufacturer-specified chaincase oil. |
| Drive Belt | Visually inspect before every ride. Replace if width is reduced by 3 mm. | Check for wear, cracks, or flat spots. Adjust tension as per the owner's manual. |
| Spark Plug | Clean and inspect annually. Replace annually. | Adjust gap to 0.51 mm. Replace more often with hard or frequent use. |
| Air Filter | Not applicable | Most models did not have a traditional air filter, but rather air intake silencers. Operate in clean, snow-covered areas. |
| Coolant | Check pre-season. Change every 2 years (if applicable). | Only applicable to liquid-cooled models (some later twin-cylinder models). Most were air-cooled. |
