Abstract

An outboard motor to be coupled to a transom of a marine vessel includes a midsection housing having a front side configured to face the transom, a back side opposite the front side, a left side, and an opposite right side. An engine having an engine block is mounted directly to and supported by the midsection housing. A driveshaft is coupled in torque transmitting relation with a crankshaft of the engine, and a portion of the driveshaft is located exterior to the midsection housing. An exhaust pipe that conveys exhaust gas from an exhaust gas outlet of the engine downwardly away from the engine is also located exterior to the midsection housing. In one example, the midsection housing serves as a sump for engine oil.
