1. A transom bracket assembly for mounting a stern drive to a transom of a marine vessel, the transom bracket assembly comprising:
an inner clamp bracket and an outer clamp bracket that are configured to clamp on opposite sides of the transom,
a transom housing that is supported by the inner clamp bracket and outer clamp bracket and configured to support a drive unit of the stern drive outside of the marine vessel and a powerhead of the stern drive inside of the marine vessel,
a vibrational dampener that elastically supports the transom housing between the inner clamp bracket and the outer clamp bracket, and
a plurality of elastomeric mounts that elastically suspends the transom housing from the inner clamp bracket.
