Abstract
An oil sump for a vertically shafted combustion engine has a housing with an upper face for sealing against a block of the engine. The sump housing defines an internal volume for containing a quantity of oil received from the engine through an oil drain opening in the upper face of the sump, and defines an exhaust inlet for receiving a flow of exhaust from the engine and directing the flow of exhaust toward an exhaust outlet along an exhaust passage defined within the housing. The housing also defines a water inlet for receiving a flow of cooling water into a water passage within the housing about the exhaust passage. The sump also includes means for securely mounting the engine within a boat hull. In some marine applications, seawater or fresh water coolant is discharged into the exhaust gas stream at an attached exhaust elbow.
