The Mooney M20K — including the 231 and 252 — is the turbocharged member of the efficient Mooney line, adding high-altitude capability to Mooney's legendary speed-per-gallon.
Key takeaways
- Turbocharged efficiency: fast and high-flying for the fuel.
- Retractable and slippery: classic Mooney speed.
- Turbo and gear add maintenance and insurance considerations.
About the Mooney M20K (231/252)
The M20K pairs the efficient Mooney airframe with a turbocharged Continental engine, cruising around 190+ knots at altitude. The 252 refined the earlier 231. Turbocharger and retractable-gear condition are key inspection items; Mooney is out of production, so a specialist pre-buy helps.

Is the Mooney M20K (231/252) Right for You?
The Mooney M20K (231/252) suits owners who want speed and capability in a single, and who are ready for the training, insurance, and cost that higher performance brings. It rewards a proficient, current pilot. If you're newer, plan for transition training — it helps both safety and insurance.
Ownership & Operating Costs
- Fuel: higher — a bigger engine burns more.
- Insurance: performance-priced; transition training and time-in-type matter.
- Systems: budget for retractable gear, turbo, or other complexity if fitted.
- Engine reserve: set aside per flight hour toward overhaul.

What to Check When Buying
Check engine time, the retractable gear and/or turbo systems if fitted, avionics, damage history, and complete logs. On a higher-performance single, a type-experienced pre-buy and a realistic insurance/training plan matter as much as the airframe.
Financing a Mooney M20K (231/252)
A Mooney M20K (231/252) finances as a piston single (15–20% down, up to 20 years), but as a higher-performance airplane, insurance and transition training carry extra weight and must be arranged before funding.
