These figures are typical for the model, not a specification for any individual aircraft. Real-world numbers vary with year, installed equipment, weight, modifications and engine condition — often by more than you would expect. Use them to compare types, and confirm anything you would act on against the Pilot's Operating Handbook for that specific airframe and a prebuy inspection.

Annual all-in

All-in at ~100 flying hours a year, using the midpoint of each range — the same figures broken out under “Cost to own” below. Your number will differ, and mostly for two reasons. Experience sets your insurance: a 2,000-hour pilot with recent training pays 30–40% less than a 200-hour owner, and student owners pay 20–40% more — on the same aircraft that is often a doubling. Location sets your hangar: a T-hangar runs $200–400 a month in the Midwest against $400–1,500 in a coastal metro, and an outside tie-down is less again. Engine reserves move too — a local shop reusing your serviceable cylinders can come in 30–50% under the national specialty-shop pricing we quote, though you trade the warranty and turnaround that comes with it. Reserves are money set aside toward a future overhaul, not a bill this year, and the annual inspection figure is the shop’s labor to look — whatever they find is separate.

Fuel, engine reserve and wear only. Insurance, hangar and the annual are already paid whether you make the trip or not, so they are not charged here.
Estimate, not a quote. Where a line shows a range, the total, per-hour and per-mile figures use its midpoint— insurance moves most with your experience and time in type, hangar with where you base the aircraft, so your own number could sit at either end. Annual inspection is the shop's labor to open and inspect — what they find is the maintenance line, which covers oil changes, plugs, tires, brakes, hoses, lights, a battery and vacuum pump amortised over their life, and the unscheduled squawks that are the largest and least predictable part of it. Reserves are sinking funds toward an overhaul, not a bill you pay this year — and note that a propeller is due on hours or calendar time, typically six years, so flying less does not put it off forever.
Strengths
- Usable rear-seat space at budget stretched-cabin price point
- Simple, carbureted O-360 engine with minimal complexity
- 13–15 KTAS slower than M20F but identical fuel burn (9.5 GPH cruise)
- Rarest stretched Mooney — only ~190 airframes on FAA certificate (1968–1970)
Weaknesses
- Carburetor icing risk in moisture conditions requires disciplined carb heat management
- Range unverified; 600 NM figure was written against 64-gallon fuel but M20G carries only 52 gallons usable
- Cylinder condition concerns identical to M20C; 180 HP engine shows wear on many examples
- Airframe extension concerns present (same as M20F); pre-buy inspection critical
Overview
The 1968 Mooney M20G Statesman was Mooney's budget stretched-cabin Mooney -- the M20F's 10-inch fuselage extension with the M20C/D's 180 HP carbureted Lycoming O-360 engine. The result was a Mooney with usable rear-seat space at a lower acquisition price than the 200 HP M20F. Production: approximately 597 units across 1968-1973.
The M20G is the least common stretched Mooney. It was discontinued after the 1973 model year as Mooney focused production on the M20F and the upcoming M20J 201, leaving the budget stretched-cabin slot empty in subsequent production.
IO-360 Conversion Option
A common STC permits replacing the O-360-A1D with the M20F's IO-360-A1A 200 HP fuel-injected engine. Cost: $45,000-$35,000 installed. After conversion, performance approaches M20F levels.
For owners considering this conversion: verify with appraiser that the post-conversion airframe will sell at M20F prices rather than M20G prices. Some buyers consider field-converted M20G-to-M20F examples less desirable than factory M20Fs due to documentation complexity.
Performance
- Cruise: 135 KTAS at 7,500 ft (75% power)
- Climb: 850 FPM at gross
- Fuel burn: 9.5 GPH cruise
- Range: 600 NM with reserves -- unverified, and written against a 64-gallon airplane
- Useful load: 925 lbs
- Fuel: 52 gallons usable, not 64
Type design limits, re-sourced from the certificate (2026-09-06)
The V-speeds, weights, seats, baggage and fuel capacity on this page now come from FAA TCDS 2A3 Revision 58, Section VIII, Model M20G. Two things a buyer should know about that pass:
- Fuel is 52 gallons usable, not 64. The page previously carried 64, which is the M20F's and M20J's figure from the adjacent sections of the same certificate. Section VIII states 52. The 600 nm range figure above was written against 64 gallons and has not been re-sourced -- treat it as unverified until the Mooney Statesman Owners Manual is read. A 19% cut in fuel does not leave a 600 nm range intact.
- The certificate's V-speeds are stated in mph with knots bracketed. Vne is 200 mph / 174 knots, maximum structural cruising 175 mph / 152 knots, maneuvering 135 mph / 117 knots, flaps extended 125 mph / 109 knots -- all on the basis the certificate calls "True Ind." The page previously carried 195 / 165 / 127, none of which appears on the certificate in either column.
Which years these figures describe. Rev 58 lists the M20G's eligible serials as 680001-680164, 690001-690020 and 700001-700006 -- 1968 through the 1970 model year, 190 airframes. This page's stated range of 1968-1973 and its "approximately 597 units" are not supported by the certificate. Every type design figure above is the certificate's and therefore describes 1968-1970; if 1971-1973 M20Gs exist they are not on Rev 58's eligibility list, and the year range is flagged for a separate re-sourcing pass rather than changed here.
The M20G is 13-15 KTAS slower than the M20F at the same fuel burn -- the carbureted 180 HP engine vs the fuel-injected 200 HP engine accounts for the entire performance difference. For pilots who don't need the extra speed and want fuel-injection-free simplicity, the G is a meaningful value.

M20Gs trade $15,000-$45,000 below equivalent M20Fs due to the speed/power gap.

ADs & Common Problems
Universal Mooney pre-buy applies. M20G-specific:
- O-360-A1D carburetor condition: Carb heat usage discipline important; carb ice potential in moisture conditions.
- Cylinder condition: Same 180 HP cylinder concerns as M20C.
- Same airframe extension concerns as M20F.
