Continental 470 AvGas Engine Series: Side View

You’ll often hear pilots referring to the Continental^® O-470 in reverent tones as “old reliable”. Powering the majority of Cessna^® 180 and 182 aircraft from 1953 through 1986, this workhorse of an engine embodies simplicity, efficiency, and ruggedness. Its track record speaks louder than words: the 470 is a brawny power plant. In fact, some versions make full power at a smooth, quiet 2400 RPM. Ranging in output from 230 to 260 horsepower, the 470 engines come equipped with either a reliable carburetor or our extremely efficient continuous flow fuel injection system. Confidence among pilots can be difficult to achieve, but if there was an award for one of the most trusted aircraft engines in the sky, the 470 series would win hands down. Just ask any pilot or owner of one.
