Owners of older Mooneys now have a new option when it's time for an engine overhaul. Lycoming recently received the FAA OK to replace the original IO-360 Lycoming engine in Mooney M20E, M20F and M20J models with a new or remanufactured IO-390-A3A6 engine. The engine provides more horsepower as well as improved climb and cruise performance, while maintaining the same footprint as the IO-360 engine, Lycoming says. The new STC shows the company's commitment to legacy aircraft, says Dennis Racine, Lycoming director of marketing and program management. About 50 service centers across the country have been authorized to complete the installations.

The STC includes a new or rebuilt IO-390-A3A6, the Slick Start System and required documentation. In addition, Hartzell has certified both two-blade and three-blade propellers for the STC. List price of the new IO-390 is $48,500, or $36,100 for the rebuilt engine, according to AOPA. Meanwhile, Mooney is trying to entice new buyers with financing at 2.99 percent for the first four years, for those who qualify. The company is also offering a leaseback option.
