Continental IO-550-F Engine – Factory New or Rebuilt

The Continental IO-550-F is a 300 horsepower, 6-cylinder, fuel-injected engine known for its smooth power, long TBO, and compatibility with high-performance singles like the Cessna 206 and 207. It’s also a popular upgrade choice under Davis Aviation and Texas Skyways STC conversions, delivering increased utility, better climb performance, and cruise fuel efficiency.

What We Need to Know Before You Order

To properly match your IO-550-F engine to your aircraft, we will confirm the following options with you during the quote process:

• Electrical System:
  Do you require a 12-volt or 24-volt starter? The default is 24V. Some early Cessna 206s may require 12V compatibility.
• Oil Cooler:
  Do you need a 7.88-inch or 8.88-inch decongealing oil cooler flange? This must match your existing cooler or STC-specified part.
• Oil System:
  Do you prefer a spin-on oil filter (integral with the oil pump housing) or a screen-type oil pickup? Most modern installations use a spin-on filter.
• Fuel Pump Type:
  Do you require an altitude-compensating fuel pump? These are often used in high-altitude operations or mountainous environments.
• Engine Mount:
  Is your aircraft equipped with a 4-point or 6-point engine mount? Cessna 206/207 aircraft and STC kits may differ—confirm your mount setup.
