A four stroke outboard motor crankcase drain plug opening attachment is described to facilitate drainage and collection of crankcase oil from four cycle outboard motors. The attachment includes a manually operable valve 20 attached by a fitting 21 to the motor drain plug opening. The valve extends to a flexible downspout 25 that extends on downwardly to an auxiliary plug 30 at a bottom end 27 thereof. The valve includes an operator 22 that can be rotated selectively to open and close the valve. The plug 30 can be selectively removed and adds a redundancy feature to facilitate unintentional drainage of oil by operation of the valve 20. An oil drainage collector 40 including opening 42 and a top end and a bale 45 mounted thereon, may be selectively secured over the valve to facilitate collection of oil. The opening and downspout, and bale are related dimensionally such that the collector container cannot swing free of the downspout when the bale is secured over the valve.
