A shock-proof electric marine engine, e.g. an engine or generator, is for a marine (Navy) ship, and includes a stator and a rotor in a housing. The stator and the rotor are connected in such a way that they are rotatably displaceable in a counter direction and in a radial / axial manner with limited slack. The rotor and stator form a displaceable unit in relation to the housing, which can be displaced away from the housing with a higher vibration overshoot range. The housing is elastically connected to the marine (navy) ship.
