After 20 successful years producing our Geo®/Suzuki® auto engine conversions for Homebuilt Aircraft, we are making the switch to the Honda® L15A as our core engine. Our newest 'STOL-Max'® 115/140+HP Honda® Jazz/Fit performance engine package is being designed specifically for the Zenith® 650/750 and our own STOL Cargo Aircraft design. Our Suzuki® redrive kits and complete engines are no longer in production. We will still offer parts/service as the new Honda® engine package uses the same proven drive components.
