Continental IO-520 Vs. IO-550

Updated: May 14, 2023

The benefits and increased performance offered for the Cessna 180 and 182 aircraft by either the Continental IO-520-D engine or the IO-550-D engine are impressive, with a few differences.


The IO-520-D engine generates 300 horsepower at an RPM of 2850, which is allowed for 5 minute intervals. On take off, at full throttle, 300 horsepower are available for five minutes, then a power change is made to bring the engine back to 285 horsepower (maximum continuous horsepower).


The IO-550-D engine generates 300 horsepower at 2,700 rpm, and has no limitations. The basic difference between the IO-520 engine and the IO-550 engine is the stroke of the piston within the cylinder, the 550 being longer, thus creating more cubic inches, and 300 sustainable horsepower through increased torque.


Both the IO-520 and 550 engine is fuel injected, equipped with a new starter, Bendix 1200 series magentos, harness and plugs, heavy duty non-congealing oil cooler, high capacity oil pump, VAR crankshaft, Heavy crankcase (7th Stud), integral oil filter and Continental Warranty.
