Overview
The Continental® 200 Series (including O-200 and IO-240 variants) is a family of 4-cylinder, air-cooled AvGas engines widely used in training, recreational and light-sport aircraft. The series is engineered for straightforward installation, predictable performance and serviceability across common general-aviation platforms.

Key design features

• Tuned induction on IO-240 for improved cylinder-to-cylinder intake-air distribution and enhanced fuel efficiency
• O-200 rated at approximately 100 continuous HP at 2750 RPM (typical 200 Series performance)
• Air-cooled, naturally aspirated four-cylinder architecture for simplified maintenance and weight efficiency

Applications

• Primary and advanced flight training aircraft
• Recreational, touring and light-sport aircraft
• Common installations: Vashon Ranger R7 (O-200), CubCrafters Carbon Cub EX (O-200), Diamond DA20-C1 (IO-240)

Manufacturing and quality
200 Series engines are produced and tested under Continental® quality control standards at the company facility in Mobile, Alabama, with traceable inspection and acceptance testing to support reliability in service.
