The story

In the 1960s, McKinnon Enterprises of Sandy, Oregon started rebuilding Grumman Geese around PT6 turboprops, with retractable wingtip floats and more fuel. Only a handful of turbine conversions were ever finished, and the final G-21G model carried 680 horsepower a side in an airframe designed before World War II.

Fun fact

McKinnon certified just two G-21G Turbo Geese and a single G-21E as brand-new aircraft. Seeing any turbine Goose is a very rare catch.
