Patent ID: 8839831

Claim:
A winterizing system for winterizing a boat component having a sea water system that draws a sea water into the boat component through a port that passes sea water through a hull of a boat, the winterizing system comprising: (a) a funnel with a tapered open bottom and a wider upper opening, the tapered open bottom adapted to be removably air-tight coupled to an opening in the sea water system, the upper opening side of the funnel adapted to be removably air-tight coupled to an air pressure supply tube, the funnel having no other ports so that, when an air pressure supply tube is air-tight coupled to the funnel and the funnel is air-tight coupled to the opening in the sea water system, there is an air-tight coupling between the air pressure supply tube and the opening in the sea water system, wherein the funnel include female threads that are at the tapered open bottom of the funnel; (b) an air pressure supply tube that can be removably air-tight coupled to the funnel while the funnel is air-tight coupled to the opening in the sea water system and used to pressurize the sea water system and thereby force water out of the sea water system and the component that is to be winterized through the port that passes sea water through the hull, wherein the air pressure supply tube includes male threads to couple to the female threads of the funnel when the air pressure supply tube is provided within the funnel; and (c) a spring, provided at least at the upper opening of the funnel, for removably urging the funnel into the opening in the sea water system.
