ABSTRACT:
A system for flushing the cooling system of the engine in a watercraft is provided, whereby a conduit connected to a source of fresh water is inserted into an adaptor located in the upper body of the watercraft. A self-closing valve is attached to the adaptor for sealing the adaptor, and the conduit automatically opens the valve when it is connected to the adaptor, allowing fresh water to flow through the adaptor and into the cooling jacket of the engine.
