Review SKI DOO Oem 793 Engine Motor Crankcase Non Snowmobile fits MXZ HO 800 2000–2003

The Ski-Doo 6811920 MXZ 793 800 engine is a powerful and reliable component of the MXZ 793 snowmobile models produced by Ski-Doo between the years 2000 and 2003. This engine's crankcase, specifically part number 6811920, is a crucial element that houses the engine's crankshaft and pistons.

This crankcase is made of high-strength aluminum alloy, which provides excellent durability and resistance to wear and tear. It features a dry-sump lubrication system that separates the oil tank from the engine, allowing for more oil capacity and improved oil cooling. This design not only ensures a longer engine life but also contributes to better overall performance.

The crankcase also includes an integrated oil pump, which is driven by the crankshaft to circulate oil throughout the engine. This design allows for efficient oil delivery and ensures that all engine components are adequately lubricated.

The crankcase is designed with a "scatter shield" that helps protect the engine from debris and other external elements. The shield is made of a strong, lightweight material and is strategically placed to shield the most vulnerable areas of the engine.

Additionally, the crankcase is equipped with a "snorkel" intake system that helps prevent water from entering the engine during deep water crossings. This design ensures that the engine remains dry and continues to operate effectively in various snow and weather conditions.

The Ski-Doo 6811920 MXZ 793 800 engine crankcase is a high-performance and durable component that is essential for the proper functioning of the snowmobile. It is designed to withstand the rigors of snowmobiling and deliver reliable, consistent power. Whether you're an avid snowmobiler or a weekend warrior, this crankcase is an investment in the longevity and performance of your Ski-Doo MXZ 793 snowmobile.

The Ski-Doo MXZ 793 800 engine, specifically the model with the HO 2000-2003 crankcase, is a popular choice among snowmobile enthusiasts for its power and performance. However, like any engine, it comes with its own set of pros and cons.

1. Power: The HO 2000-2003 crankcase is known for its impressive power output. This engine delivers a strong and responsive performance, making it a great choice for riders who enjoy high-speed riding and heavy towing.

2. Durability: Ski-Doo engines are known for their durability and reliability, and the MXZ 793 800 is no exception. This engine is built to withstand the rigors of snowmobile use, making it a great investment for those who plan to use their snowmobile frequently.

3. Fuel Efficiency: Compared to other engines in its class, the MXZ 793 800 is relatively fuel-efficient. This means that riders can go longer between fill-ups, saving them time and money.

1. Cost: The MXZ 793 800 engine is not a cheap investment. The HO 2000-2003 crankcase alone can cost several hundred dollars, and the cost of installation and maintenance can add up over time.

2. Complexity: This engine is complex, with many moving parts and intricate systems. This can make it more difficult to diagnose and repair, which can lead to higher repair costs and longer downtime.

3. Weight: The MXZ 793 800 engine is heavier than some other engines in its class. This can make it more difficult to maneuver, particularly for riders who are new to snowmobiling or have limited strength.

The Ski-Doo MXZ 793 800 engine with the HO 2000-2003 crankcase is a powerful and reliable choice for snowmobile enthusiasts. Its impressive power output, durability, and fuel efficiency make it a great investment for those who plan to use their snowmobile frequently. However, its high cost, complexity, and weight may make it a less desirable choice for some riders. Ultimately, the decision to buy this engine depends on your individual needs, preferences, and budget.

If you are in the market for a new snowmobile engine and are looking for power and durability, the Ski-Doo MXZ 793 800 engine with the HO 2000-2003 crankcase is a solid choice. However, be prepared for the higher cost and potential complexity of this engine. If you are on a tighter budget or are looking for a simpler engine, you may want to consider other options. Ultimately, it's important to weigh the pros and cons carefully and consult with a trusted snowmobile mechanic or dealer to help you make the best decision for your specific needs and circumstances.
