Vehicle Information
Ski-Doo Formula 470 Snowmobile (1985-1994)
The Ski-Doo Formula 470 series, produced from 1985 to 1994, was a popular snowmobile known for its reliable liquid-cooled Rotax twin-cylinder engine, consistently around 462cc to 467cc. This "470" engine was praised for its strong low-end and mid-range torque, making it a capable and enjoyable ride. While earlier models like the 1985 Formula MX offered "gobs of mid-range grunt," later performance trims, such as the 1994 Formula MXZ-X 470, could produce close to 100 horsepower. Throughout its production, the Formula 470 saw significant chassis and suspension advancements. The series debuted in 1985 with the innovative Progressive Reaction Suspension (PRS) chassis. In 1992, it received the C7 rear suspension and a wider ski stance (from 36 to 40 inches) for enhanced stability, along with a more aerodynamic hood. The 1993 models further refined the C-7 suspension. By 1994, the lineup expanded with the performance-oriented Formula MXZ and the mountain-specific Summit 470, featuring plastic skis and the Rotax High Altitude Compensator (HAC) system. The core 462-467cc Rotax engine remained a consistent and reliable powerplant across these evolutions. Q: How do I know which Formula 470 model I have?
A: The Ski-Doo Formula 470 series includes various trims and configurations from 1985 to 1994. To ensure you select the correct parts, please use our year and model selector on this page. Q: Are parts for all 1985-1994 Formula 470 models interchangeable?
A: While many components are shared, significant changes occurred in chassis and suspension over the years. Always refer to your specific model year using our selector for guaranteed fitment.
Maintenance
| Component | Interval | Details |
| Injection Oil | Before every ride | 2-stroke snowmobiles do not have a traditional engine oil filter. Check the injection oil level and top off as needed, as running out of oil can severely damage the engine. |
| Drive Belt | Inspect every 50 hours or 2,400 to 4,800 km | Inspect the belt for wear before or after each ride. Replace if worn or if performance decreases. Clean clutch faces annually or if performance degrades. |
| Spark Plugs | Annually | Change spark plugs annually. During any tune-up, remove, examine, and replace them if fouled or worn. |
| Air Filter | Check and replace as needed | Check the air filter and replace if too dirty. A clogged air silencer can contribute to engine issues. |
| Coolant | Every 2 years | Also check all fluid levels, including coolant, after each ride. |
| Chaincase Oil | Annually | Drain and replace chaincase oil at the end of each season or annually. |
These intervals are based on general 2-stroke snowmobile maintenance practices from that era. For precise information, consult your model's official owner's manual.
