It is simple. We believe that 180HP and a fixed pitch propeller provides the best combination of power and reduced complexity for a Cessna 172. The proven and reliable factory new Lycoming O-360-A4M engine comes complete from Air Plains with roller tappets, Slick Magneto, EIS (Electronic Ignition System), wiring harness, spark plugs, carburetor and ring gear. The engine is paired with a light weight Sky-Tec starter and Plane-Power alternator.
