Vehicle Information
Ski-Doo Alpine 500 Snowmobile (1983-1987)
The Ski-Doo Alpine 500, produced from 1983 to 1987, was renowned for its robust utility and legendary twin-track design. This workhorse snowmobile was consistently powered by a fan-cooled, twin-cylinder Rotax 503 engine. Its displacement is commonly cited as 496.7 cc or 503 cc, referring to the same reliable powerplant. In its standard dual-carburetor configuration, the Rotax 503 delivered approximately 50 horsepower (37 kW) at 6800 RPM. Throughout its 1983-1987 production run, the Alpine 500 was offered as a single, primary model without distinct trim levels. There were no significant mid-cycle generation or engine changes during these years. The consistent "503 F/C" designation in parts and model descriptions confirms its unchanging core identity. FAQ:

Maintenance
| Component | Interval | Details |
| Oil Injection Reservoir Level | Before every ride | Check level to prevent engine damage. 2-stroke engines do not have a traditional engine oil filter. |
| Drive Belt | Inspect before every ride; replace every 2,400 to 4,800 km | Inspect frequently for signs of wear (cracking, uneven wear, flat spots, fraying). Replace if worn. Check tension and height. |
| Spark Plug | Annually or at the beginning of each season | Check for engine misfires, rough idle, and loss of power. Recommended type: NGK BR7ES. |
| Air Filter | Regularly | Clean to prevent clogging, which restricts airflow and reduces performance. |
