The Teledyne Continental C75, C85, C90, and O-200 series engines are a family of four-cylinder, horizontally opposed, air-cooled gasoline engines produced by Teledyne Continental Motors. These engines are widely used in general aviation aircraft, with applications ranging from light sport aircraft to single-engine trainers and utility aircraft. The C75, C85, and C90 models are all direct-drive engines, while the O-200 is a geared engine, offering a wider range of propeller speed options. Despite their similar design, these engines offer varying performance, with their respective horsepower outputs ranging from 75 to 200 hp.

These Continental engines are known for their robust construction, reliability, and ease of maintenance. They feature a simple, yet durable design, with a cast-aluminum crankcase, steel connecting rods, and forged aluminum pistons. Their air-cooled design eliminates the need for a complex cooling system, simplifying maintenance and reducing weight. The engines are also known for their relatively low operating costs, making them an attractive option for owners and operators of general aviation aircraft. The C75, C85, and C90 series engines have a long history of proven reliability, with many aircraft still in service with these engines after decades of operation. However, these engines are no longer in production, and owners rely on specialized service manuals and parts suppliers for maintenance and overhauls. The service overhaul manual for the Continental C75, C85, C90, and O-200 series engines is a crucial resource for mechanics and aircraft owners, providing detailed instructions and specifications for all aspects of engine maintenance and repair.
