ABSTRACT:
An automatic boat drain for siphoning water from the interior of a boat, the drain including a flow tube secured to the exterior of the boat transom with the inlet end of the flow tube being below the water surface and oriented so that water is forced to flow through the flow tube as the boat moves forward above a minimum speed, the outlet end of the flow tube being above the water surface, an entraining tube having the inlet end adjacent the interior bottom of the boat, and a venturi forming connection positioned above the water surface connecting the entraining tube outlet end to the flow tube adjacent to and spaced from the flow tube outlet end whereby as the boat moves through water the flow of water forced through the flow tube will produce a venturi effect to drain water from the boat interior while the venturi positioned above the water surface prevents the possibility of water being siphoning into the boat.
