Abstract: A device to facilitate removal of oil from an outboard motor having an oil tank located in its drive shaft housing. An oil removal tube fitted in a bore through the adapter plate of the motor extends downwardly to the bottom of the oil tank and projects above the adapter plate and terminates inside the cowling for the motor. The top of the tube may be threaded to accept a connector to an oil removal pump.

Abstract: In an outboard motor having a four cycle power head, a drive shaft housing and an adapter plate therebetween, an oil sump in the drive shaft housing and a lubricating oil system to supply oil to the bearings of the power head, a baffle system including the adapter plate and a second planar baffle between the adapter plate and the drive shaft housing. Oil passages through the adapter plate and the second baffle are positioned on opposite sides of the power head from each other and are longitudinally separated from each other so that the oil will not flow from the oil sump back over the baffles and into the power head when the motor is horizontal.
