ABSTRACT:
A quick drain device for an inboard boat engine, especially an engine of the type having a water jacket to which a plurality of drain cocks are connected through which the engine coolant must be drained after each use of the engine. The quick drain device is in the form of a barrel having a plurality of lateral tube radiating therefrom. An expandable stopper is received within the barrel and covers the ends of the tubes and thereby prevents flow therethrough. The other ends of the lateral tubes are connected to the drain cocks or drain plugs located on the engine block. Removal to the expandable stopper simultaneously drains all of the drain plugs.
