ABSTRACT:
The outboard engine flushing system frees the boater from need to lean out beyond the boat transom to access the conventional engine cooling flush components. The system includes a Y hose connector attached to the conventional inlet fitting beneath the engine cowling, and a forwardly extending flexible tube attached to another leg of the Y connector. The conventional return line normally connected to the cowl bottom inlet fitting is connected to the remaining leg of the Y connector. A shutoff valve is provided at the forward end of the flexible tube. To flush the cooling system of the engine, the boater connects a conventional water hose to the forward end of the flexible tube extending from the Y connector, opens the valve, and turns on the water. When flushing is complete, the shutoff valve is closed and the water hose disconnected to ready the boat and engine for further operation.
