The Zenoah G-25 is a single cylinder, two stroke, carburetted aircraft engine, with optional fuel injection, designed for use on ultralight aircraft

The Zenoah G-25 is equipped with single capacitor discharge ignition and a single Mikuni slide-type carburetor. It is equipped with a recoil starter system or optionally electric start and a 2.5 or 2.8:1 belt reduction drive.

The engine runs on a mixture of unleaded auto fuel and oil.
