Continental IO-360-CB Engine – FAA-Approved Replacement for IO-360-C

The Continental IO-360-CB is the FAA-approved direct replacement for the legacy IO-360-C engine, which is no longer in production. Originally installed in the Cessna 337 Skymaster and its military and international variants, the IO-360-C has been superseded by the CB model—offering the same performance, mounting compatibility, and certification with modern factory support.

Note: The Continental IO-360-C is no longer available. Customers must now order the IO-360-CB. Continental will accept the IO-360-C core for full core credit when ordering a CB replacement.
