  • Apparatus and method for boat motor winterizing
    Patent number: 9011190
    Abstract: There is provided a portable (easily carried by one person), re-usable apparatus for protecting an engine of a watercraft by filling engine passageways with a protective fluid. The apparatus does not require a pump for the protective fluid. In operation, filling the container with protective fluid, clamping the flexible cup to the water intake ports, and opening the valve permits the running engine of the watercraft to suction protective fluid into cooling fluid passageways within the engine. The entire operation is carried out without a pump to pressurize the protective fluid, and minimizes fluid safe disposal requirements.
