Vehicle Information
Ski-Doo MXZ 850 Snowmobile (2017-2026)
The Ski-Doo MXZ 850 series, powered by the Rotax 850 E-TEC engine, has seen significant developments and a variety of trims from 2017 to 2026. These performance snowmobiles are known for their agility and power, featuring a naturally aspirated 850 E-TEC engine producing 165 horsepower. A more powerful variant, the 850 E-TEC Turbo R, was introduced, offering 180 horsepower.
The REV Gen4 platform was launched in 2017, bringing a narrower chassis and improved ergonomics. In 2023, the REV Gen5 platform was introduced for MXZ 850 E-TEC models, featuring a refined design, new LED headlights, and an engine cradle for reduced noise and vibration. The 180-horsepower 850 E-TEC Turbo R engine also became available on select MXZ models starting in 2023, and more broadly in 2024.

Maintenance
| Component | Interval | Details |
| Oil Filter / Oil Injection Pump Strainer | Check oil level before every ride; Inspect/clean strainer every 3 years or 10,000 km; Replace in-line fuel filter every 5 years | 2-stroke engines do not have a traditional engine oil filter. Oil is mixed with fuel via an injection system. |
| Drive Belt | Inspect annually (pre-season) or every 3,000 km | Visually check and clean drive and driven pulleys. Inspect before every ride for signs of wear (cracking, fraying). |
| Spark Plug | Replace every 3 years or 10 000 km | It is recommended to replace them before the start of the season for moderate use. |
| Air Filter | Clean regularly | No specific periodic replacement interval is detailed. Clean to prevent clogging. |
| Coolant | Check density annually (pre-season) or every 3,000 km; Replace every 5 years | Check coolant level before every ride when the engine is cold. |
