The present invention relates to a hydro engine mount fixed in a housing as an insulator manufactured with an elastic material and connected to a core supporting the weight of an engine and a lower cup connected to the lower end of the insulator are connected. The housing a lower body in which the lower cup is inserted into the inner circumference; an upper body wherein the core is located inside by being formed on the upper side of the lower body and an expansion unit protruding outsides to have larger inner diameter than the diameter of the lower body is formed; and a stopper mounted on the expansion unit. The stopper is characterized by being arranged on the outside while facing the core in order to limit movements of the core according to elastic deformation of the insulator. The present invention can prevent excessive elastic deformation of the insulator caused by sudden acceleration or sudden deceleration. The stopper of the present invention can obtain the effect of increasing the thickness of the insulator without increasing a size of the whole engine mount by being manufactured with the elastic material.
