Mooney 231 Aircraft

The Mooney 231 (M20K) is the turbocharged Mooney — introduced 1979 with a 210 hp Continental TSIO-360 engine that holds power to altitude, cruising in the low 200s of knots above 16,000 feet. The original 231 was followed by the intercooled 252 (1986) and the further-refined Encore (1997+), each addressing the original's heat-management issues. For high, hot or mountain flying in a Mooney, the M20K family is the right choice — the price is somewhat thirstier fuel burn and the maintenance overhead of a turbocharged engine.

Buying a Used Mooney 231

Buying a Mooney 231 comes down to a focused pre-purchase checklist — here is what matters most on this model:

What to check before buying

  • TSIO-360 turbo system — turbo condition and history; the original 231 ran hot, so look for Merlyn upper-deck pressure controller or other heat-management mods.
  • Intercooler retrofit — original 231s lack intercoolers; an intercooler mod or upgrade to 252/Encore internals is a major value driver.
  • Engine time + cylinder history — the TSIO-360 is sensitive to operation; pristine cylinder history matters.
  • Gear, tank reseal, avionics — standard Mooney items.

Which 231/M20K? A 252 or Encore is a more refined turbo Mooney than the original 231; an intercooled-retrofit 231 is the value path. The original 231 is the cheapest M20K entry but needs careful turbo-system review.
