ABSTRACT:
Several embodiments of vibration damping devices for preventing the transmission of vibrations from the power head of an outboard motor to the transom of the boat to which it is attached. In each embodiment, a vibration damping pad is interposed between the power head and the drive shaft housing to isolate vibrations. In accordance with another feature of the invention, a flexible coupling is interposed between the engine output shaft and the drive shaft for permitting relative vibration damping between the power head and the drive shaft housing. A number of embodiments are disclosed that show various arrangements through which the vibration damping pad is affixed to a pair of supporting plates. In addition, an arrangement is provided for cooling the vibration damping pad in the area through which exhaust gases are passed from the engine to the drive shaft housing.
