Abstract: System and method for protecting a cooling system of a liquid-cooled engine using a protective material. This system enables a boat operator to flush the cooling system using salt, brackish or fresh water. In one embodiment, the system includes a reservoir, a dispenser and a connection device. The reservoir is capable of containing a protective material that can include, among others properties, anticorrosive properties. The dispenser controls release of the protective material from the reservoir and can be controlled manually or through a control unit. The system is coupled with the cooling system downstream from raw water intake ports and upstream from a terminal end of the cooling system as the cooling system terminates at the exhaust port. The protective fluid can be dispensed using gravity feed or a pump.

Abstract: Stern drive assembly configured for utilization in an inboard/outboard power plant for a boat. The stern drive assembly includes a central rigid core that is configured at an upper portion to be coupled to the stern of a carrying boat. A lower portion of the core is designed to accept a boat-moving force generated by a water propulsion unit that is coupled thereto. A thin-walled housing is configured to be secured about a predominance of the centrally located rigid core. The housing has an outer surface that establishes an exterior of the stern drive assembly and an inner surface directed generally toward the central rigid core. A portion of an exterior surface of the central rigid core is configured to cooperate with a corresponding portion of the inner surface of the thin-walled housing. These two portions, when in cooperative orientation one with the other, form a functional feature for the stern drive assembly.
