The Easy- Flow Flushing system is the easiest most reliable flushing system available for inboard engines and out-drives. The Easy- Flow system can flush your boat either in or out of the water by simply quick connecting your garden hose to the Easy- Flow Valve at a convenient location on your boat. It flushes the entire cooling system and the out-drive with the maximum supply of city water. The Easy- Flow quick connect cap quickly and securely seals the valve shut when done.

The Easy- Flow valve allows you to disconnect from flushing, quick connect to a water nozzle, and spray down your boat without having to turn off the water. Or you can winterize your boat engine by draining your circulation system, closing the seacock, and closing off the outdrive intake vents. Simply quick connect one end of a shortened garden hose to the Easy- Flow inlet and insert the other end of the hose into a container of antifreeze and start your engine to suck the antifreeze into the circulations system. Disconnect the hose and quick connect the Easy- Flow Cap to complete the winterization of your boat.
