Vehicle Information
Moto-Ski Grand Prix 500 Snowmobile (1979-1981)
The Moto-Ski Grand Prix 500, produced from 1979 to 1981, was a reliable and performance-oriented touring snowmobile. These models were powered by a Rotax 503 twin-cylinder, fan-cooled engine, with a displacement of approximately 497cc or 503cc. This engine, adapted from snowmobiles for ultralight aircraft, developed approximately 50 horsepower (37 kW). The lineup evolved with the introduction of the Grand Prix Special 500 in 1979, characterized by its distinctive orange styling. In 1980, proven design updates were integrated, and in 1981, the Grand Prix Special MX was launched, featuring an advanced coil spring front suspension and a unique hood design. The Rotax 503 engine remained consistent across all trims and production years. Q: How can I confirm part compatibility for my Moto-Ski Grand Prix 500?

Maintenance
| Component | Interval | Details |
| General Lubrication | Every 25 hours of operation | Includes drive chain, front axle bearings, driven pulley eccentric, and steering mechanism. Lubricate until new grease appears. |
| Drive Belt | Regular check | Check condition (cracks, fraying, uneven wear). Replace if width is less than 2.5 cm. |
| Spark Plugs | Inspect and replace as needed | Check for fouling or defects. Replace if defective or fouled, especially during pre-season preparation. |
| Air Filter | Inspect and clean/replace as needed | Especially in wet or dusty conditions. Fuel filter cartridge should be changed if necessary and fuel tank cleaned. |
| Oil Filter | Not applicable | These two-stroke engine models do not use a conventional oil filter like four-stroke engines. |
| Chaincase Oil | Annually or every 3,200 to 6,000 km, or every two years | Check level. It is recommended to change the oil at the end of the season to prevent moisture during storage. |
