1980 Mooney M20K 231Single-Engine Piston Aircraft • Longview, TX, USA

This 1980 Mooney M20K 231, registration N231MH, is a one-owner-from-new aircraft with 2,675 total time on the airframe and a damage-free history, as the listing notes "NDH". It has been hangared its entire life in the dry western US. The standout feature is the Rocket Engineering 'Rocket 305' Conversion, which replaces the original 210hp Continental 360ci engine with a fire-breathing Continental TSIO-520-NB producing 305hp on a 1,600-hour TBO. The engine has just 153 hours since major overhaul by Premier Aircraft Engines in Troutdale, Oregon, and the full-feathering McCauley three-blade propeller has 275 hours since overhaul.
