  • Patent number: 4878865
    Abstract: A system for supporting an outboard propulsion unit to the transom of a boat. The system is comprised of a pair of transom brackets which are fixedly secured to the boat transom and positioned spaced from each other to support the outboard propulsion unit. A pair of deflector side plate sections are provided to be respectively integral with the transom brackets, and extend downwardly and rearwardly relative to the boat transom. Additionally, a deflector bottom plate section is provided to connect the lower end portions of the deflector side plate sections. The deflector bottom plate section extends rearwardly relative to the boat transom and positioned between the boat and the outboard propulsion unit. The deflector side and bottom plate sections constitute a deflector for regulating backward water flow from the boat transom, thereby preventing generation of water splash.
