Abstract
In an outboard engine system, an inertia force a generated longitudinally by a piston is countervailed by an inertia force b generated by a crankshaft , and inertia forces c and d subsidiarily laterally generated vibrate a body of the outboard engine system laterally about a phantom center point C of vibration. At this time, an elastomeric member resiliently supporting the system body on a hull has a rigidity in a tangent direction (in the direction of L ) about the phantom center point C of vibration, which is set to be lower than a rigidity in a radial direction (in the direction of L ) about the phantom center point C of vibration. Therefore, the lateral vibration is reduced effectively due to the lower rigidity of the elastomeric member . Thrusts e and f generated by a propeller and acting in a longitudinal direction (in the direction of L ) are transmitted to the hull through the elastomeric member . However, the rigidity of the elastomeric member in the longitudinal direction is set to be higher and hence, the thrusts e and f can be transmitted effectively to the hull.
