Vehicle Information
Ski-Doo Citation 377 Snowmobile (1980-1983)
The Ski-Doo Citation 377, produced from 1980 to 1983, was a popular and reliable snowmobile known for its compact design and efficient performance. It was primarily powered by a fan-cooled, twin-cylinder Rotax engine, typically around 368cc, often referred to as the 377cc. This period saw the Citation line offered in several trims, including the Citation 3500 (with a 268cc engine), the Citation 4500 (featuring the 368cc engine with a single carburetor, producing about 34 hp), and the sportier Citation SS (also with the 368cc engine but equipped with dual carburetors for approximately 40 hp). A significant generational change occurred for the 1980 model year, when the Citation received an all-new chassis featuring an aluminum tunnel, a steel front section, and an all-rubber track, replacing earlier designs. Within the 1980-1983 range, the core 368cc engine remained consistent, with performance variations mainly due to carburetor configurations. No further major mid-cycle generation changes or engine overhauls were introduced during these specific years. FAQ:

Maintenance
| Component | Interval | Details |
| Oil (2-stroke injection oil) | Before every ride and with every refueling | The 2-stroke oil injection system does not require a traditional oil change. Check the oil level frequently and refill the reservoir with high-quality 2-stroke oil (e.g., TC-W3) to prevent engine damage. |
| Oil Filter | Not applicable | The 2-stroke engine with oil injection typically does not have an engine oil filter like a 4-stroke engine. Therefore, there is no specific maintenance interval for an engine oil filter. |
| Drive Belt | Before every ride and every 50 hours | Inspect the belt for signs of wear (cracking, fraying). Replace immediately if necessary. It is recommended to start each season with a fresh belt and check tension regularly. |
| Spark Plugs | Annually or every 50 hours | Replace spark plugs to ensure optimal engine performance. |
| Air Filter | Check regularly, replace if dirty | Check the air filter when adding fluids and replace it if it is dirty to maintain proper air intake. |
| Coolant | Every 2 years or annually | Change the coolant to ensure the efficiency of the cooling system, especially before the winter season. |
