ABSTRACT:
An outboard drive having an improved arrangement for absorbing torsional vibrations and isolating the drive shaft from them. Several embodiments of torsional vibration dampers are disclosed each of which includes a first member that is detachably connected to the drive shaft and an inertial member that is coupled to the first member. In some embodiments, this coupling is achieved by an elastomeric sleeve and in others it is achieved by means of a viscous fluid.
