Description

Fully sorted, continuously upgraded 231 with the engine and turbo configuration every Mooney buyer is looking for. No damage history. This airplane received a nose-to-tail refurbishment beginning in 2022 and presents in excellent condition inside and out, with complete logs and extensive documentation. Fresh annual March 2026. Engine & Prop — the right setup: Continental TSIO-360-LB factory rebuilt/zero-timed by Continental 9/29/2000 — now just 904 SFRM. The LB is the desirable cool-running variant, further upgraded with the Merlyn automatic upper-deck wastegate and intercooler conversion — lower TITs and CHTs, higher critical altitude, stronger high-altitude cruise. New turbocharger, flow divider, and engine-driven fuel pump in 2021. Complete new exhaust system in 2025. Prop overhauled concurrent with engine — 904 SPOH. Engine zero-timed with fresh Continental logbook — full traceability since rebuild. Airframe — 4,083 TT, No Damage History: •Complete strip and reseal of fuel tanks by Wet Wingologists East, 2023 ($15,000) — the tank question is answered on this airplane •New custom paint by Hawk Aircraft, 2023 (completed after the reseal — done in the right order) •Speed brakes completely overhauled with new cables •Empty weight 1,963.2 lbs (new W&B March 2026) — 936.8 lb useful load •Annual completed March 13, 2026 Interior: New custom interior, 2023. Excellent throughout. Avionics & Autopilot: Garmin GNS 430W (WAAS), ADS-B In/Out, Garmin Aera 760 hard-wired in the panel. King KFC 200 autopilot with flight director — fully functional and flying great. Complete logbooks. This is not a project or a flip — it's an airplane that's had the money spent, with receipts to prove it. Turn-key, ready to go fast and high.
