In an engine-generator set (10), the generator (13) has a first shaft (25) driving a generator armature (27) and also has a second shaft (19) in spaced relationship to the first shaft (25). The second shaft (19) i s coupled to the engine (11) and there is a respective gear (21 or 23) on each of the shafts (19 25) which provides a "step-down" gear reductio n for powering the generator (13) at, e.g., 1800 rpm, where the engine speed is greater than 1800 rpm. Preferably, the engine (11) is coupled to the generator armature shaft (25) through a torsional coupling (17) for isolating engine vibration from the generator (13).
