ABSTRACT:
The invention relates to a shock and vibration damping suspension system for mounting a power unit in relation to an engine bed or the like. The power unit comprises a motor or engine and a power transmission arrangement coupled thereto, preferably an inboard-outboard drive for watercraft. The suspension system includes suspension elements which are mounted between the power unit and the engine bed and are provided with damping devices made of resilient material. The invention is characterized in that the suspension elements located in parts of the power unit which, in operation are subjected to lifting forces, are of a first kind where the damping device is subjected to compression and shear forces under the influence of the lifting forces, while the suspension elements located in remaining parts of the power unit are of a second kind where the damping device is subjected to compression and shear forces under the influence of downwardly acting forces.
