ABSTRACT:
A fluid flow tube (9) is provided which extends from the lower portion of the engine oil pan (7) to a point on the boat transom (2) below the pan. The upper end portion of the tube is connected through a control valve (10) which communicates with the pan interior. The lower or discharge tube end portion is connected through a fitting (11) extending through the transom. A removable plug (17) is associated with the fitting and, when removed, permits oil to drain out through the transom and into an oil collection receptacle when the control valve is open.
