ABSTRACT:
A marine engine oil drainage device and combination are provided for gravitating oil from the oil pan of an inboard marine engine. The discharge device includes a tubular casing which is snugly disposed within the drainage port in the stern of the vessel. The casing is hollow and has an exterior and an interior. The walls of the casing have drainage openings for allowing water in the bottom of the vessel to drain into the casing and out of the vessel via the drainage port. Within the casing is a short nipple affixed to the casing wall opposite the discharge port. The nipple is in fluid communication with an oil drain conduit which runs from the oil pan and connects with the exterior of the casing. In one embodiment, an internal valve is disposed within the casing which can be actuated by a special tool which is thrust into the discharge end of the casing.
