There are three ways to get a 180 horsepower engine into your 172:

Option One
Send your 0-320 Series engine and Penn Yan Aero will overhaul and convert your engine by replacing the crankshaft, connecting rods, cylinders, pistons, and carburetor converting it to a Type Certified, FAA Approved 180 horsepower Lycoming 0-360-A4M engine. Penn Yan Aero uses only genuine Lycoming replacement parts. Penn Yan Aero dynamically balances the crankshaft and ring gear assembly to within 0.20 ounce/inches. The result is a significantly smoother running engine. A smooth running engine creates less noise and less vibration resulting in less stress on accessories, airframe, and people. You'll enjoy better performance and less pilot and passenger fatigue with this engine.

Your engine will be precisely assembled and set-up by certified Penn Yan Aero craftsman to Penn Yan Aero's meticulous build and stringent quality standards. It will be delivered complete with; inner cylinder baffles; two Slick magnetos and ignition harness; spark plugs; Sky-Tec lightweight starter; vernatherm thermostat bypass valve; oil filter adapter, oil filter, and oil dip stick.

Before the engine is approved for shipment, it is thoroughly inspected and tested by Penn Yan Aero. It is run through the full RPM range for a minimum of 1-1/2 hours including a 30 minute full power run. Dynamic tests include horsepower, oil pressure, and temperature, cylinder head temperature and exhaust gas temperature, crankcase and manifold pressure, compression on all cylinders, ignition system, fuel delivery system, magneto drop, and oil and oil filter analysis.

The result is an extremely high value, incredibly reliable, smooth running, long lasting Penn Yan Aero 180 horsepower SuperHawk O-360-A4M engine. The engine has a 2000 hour TBO and is backed by Penn Yan Aero's renowned 100% parts and labor, 2 year, 500 hour, prorated to TBO warranty, supported worldwide and fully transferable.

Option Two
Penn Yan Aero can provide you with a factory new Lycoming 0-360-A4M SuperHawk specification engine with the SuperHawk propeller and installation kit in exchange for your normally run-out, repairable 0-320 Series Lycoming engine. This option requires up to 120 days process time. Prices include the exchange of your acceptable cores, plus shipping.
