Cessna 337G Aircraft (Super Skymaster)

← Cessna 337 family

The Cessna 337G Skymaster is a six-seat, twin-engine piston aircraft with the unique push-pull centerline thrust configuration. Burning approximately 18 gallons per hour total, the 337G eliminates asymmetric thrust hazards in an engine failure, making it the safest conventional twin for single-engine operations. It appeals to practical pilots who value twin-engine safety without the complexity of managing critical engines.

Cessna 337G Price Guide

Key price factors: engine time to overhaul, year and airframe hours, avionics, damage history and logbook completeness — see the buying guide below for the full pre-purchase checklist.

Cessna 337G Cost of Ownership estimate
Fuel (18.0 GPH × $6.20, 100 hrs)$11,160/yr
Annual Fixed (hangar, insurance, annual)$25,000/yr
Variable (per hour)$260/hr
Engine Overhaul (every 1,500 hrs)$25,000
Estimates at 100 flight hours/year. Actual costs vary by usage, location and insurance.

The 337G runs two Continental IO-360 engines at a combined burn of around 18 gph - significantly more than comparable six-seat singles. Two engines mean two annual overhaul events, doubled ignition inspection, and two prop governors. Insurance for the 337 is typically lower than conventional twins for pilots without established multi-engine time, which partially offsets the higher fuel cost. The retractable gear adds hydraulic-system maintenance. For buyers comparing 337G to a six-seat single, the operating premium reflects twin-engine safety, not performance alone.

Buying a Used Cessna 337G

Buying a Cessna 337G comes down to a focused pre-purchase checklist — here is what matters most on this model:

What to check before buying

The Cessna 337G Super Skymaster is a twin-engine aircraft with a unique centerline-thrust (push-pull) design: one Continental IO-360 engine (210 hp) in the nose and one in the tail, both driving the aircraft on the fuselage centerline. The result is six seats, retractable gear, approximately 175 knots cruise, 900 nm range, and a 19,500-foot service ceiling - with twin-engine redundancy and none of the asymmetric-thrust handling of conventional twins.

The centerline-thrust advantage. A conventional twin that loses an engine goes asymmetric and requires immediate control input to counter the yaw. The 337's push-pull layout keeps both engines on the centerline, so an engine failure produces minimal yaw and a far more manageable emergency. This is the Skymaster's defining characteristic and why it was used as a stepping stone to multi-engine ratings. Note that a multi-engine rating is still required to act as pilot-in-command.

Twin economics versus singles. Operating two IO-360s at around 18 gph combined costs materially more per hour than a six-seat piston single. Two engines also mean two sets of annual maintenance, two overhauls, and two ignition systems. The 337 earns its higher cost through centerline-thrust safety, twin redundancy, and the step over six-seat singles.

337 versus conventional twins. Against a Cessna 310, the 337G is slower (about 175 kt vs 195 kt) with lower useful load, but offers simpler engine-out procedures and lower insurance for pilots transitioning to twins. The 310 is the higher-performance conventional-twin comparison for pilots comfortable with asymmetric-thrust handling.

Buy it if you need six seats with twin-engine safety margins and want to avoid conventional-twin asymmetric handling - for pilots moving from singles to twins, or operators who value the centerline-thrust safety model over maximum cruise speed.

Frequently Asked Questions — Cessna 337G

About the Cessna 337G Skymaster
The Cessna 337G was produced in the mid-1970s, using two Continental IO-360 engines (210 hp each) in a push-pull centerline-thrust configuration — one in the nose and one as a pusher at the rear. The Skymaster's defining feature is this centerline-thrust twin design: both engines on the fuselage centerline, eliminating asymmetric thrust on single-engine failure. The 337G is a mid-sequence Skymaster with model-year refinements over earlier variants.
What distinguishes the 337G from other Skymasters?
Model-year refinements — changes to avionics, trim, and detail within the IO-360-powered 337 series. The 337F, 337G, and 337H share the same push-pull twin configuration and IO-360 engine family; between letters, condition drives the purchase decision more than the specific letter.
Why do pilots choose the 337 over a conventional twin?
The centerline-thrust configuration eliminates the most dangerous single-engine scenario in conventional twins — asymmetric thrust and the resulting yaw/roll on engine failure. On a 337, engine failure produces drag but no yaw, making single-engine handling much more manageable for pilots without extensive multi-engine experience. This makes the Skymaster popular with pilots transitioning from singles who want twin-engine redundancy without the full asymmetric-thrust training burden.
What are the 337's maintenance considerations?
Two IO-360 engines to maintain (a doubled overhaul budget versus a single). The rear engine runs hotter due to reduced airflow and requires careful monitoring. The push-pull driveshaft and rear engine mount — unique to the 337 configuration — require inspection by Skymaster-experienced shops.
Is the 337G a good used-aircraft buy?
For pilots who want the centerline-thrust twin philosophy at piston-single prices. The 337 is less common than conventional twins (310/340) and has a smaller support community, but dedicated Skymaster shops exist. The rear-engine heat management and the unique configuration require specialist familiarity at annual and maintenance.
