Abstract
A vibration dampening system incorporates an inertia mass that is disposed within a hollow portion of an impeller structure. The inertia mass is attached to one or more elastomeric members which are, in turn, attached to an inside surface of a tubular portion of the impeller structure. The annular inertia mass and its elastomeric legs are particularly designed to dampen and counteract a particular frequency at which the propulsion system vibrates when the internal combustion engine is operated at idle speed.
