McKinnon Turbo Goose
The Turbo Goose
“A 1937 hull with a turbine heart — and almost none left.”
McKinnon Enterprises (Grumman airframe) · private
In the 1960s, McKinnon Enterprises of Sandy, Oregon took war-surplus Grumman Geese and rebuilt them around PT6 turboprops — stretched noses, more fuel, retractable floats, nearly double the speed of the radials they replaced. Only a handful of conversions were ever finished, and the final G-21G model carried 680 horsepower a side in an airframe designed before World War II.
The registry lists just one turbine Goose still active. If one of these crosses your map, you are looking at the rarest kind of catch there is.
Looks like a Goose that hit the gym: long pointed turbine nacelles with exhaust stacks instead of round radial cowls. If the hull says 1937 but the engines whine, you've found the turbine.
