Abstract
A stern drive for a marine vessel comprises an internal combustion engine that extends in a longitudinal direction, a horizontal direction that is perpendicular to the longitudinal direction, and a vertical direction that is perpendicular to the longitudinal direction and perpendicular to the horizontal direction. An engine output shaft extends in the longitudinal direction and is driven to rotate by the internal combustion engine. A cooling water sea pump is powered by rotation of the engine output shaft to pump cooling water to the internal combustion engine. The cooling water sea pump comprises a first pump input shaft that extends parallel to the engine output shaft, a second pump input shaft that extends transversely to the first pump input shaft and is driven to rotate by the first pump input shaft, and an impeller that is driven to rotate by the second pump input shaft to pump the cooling water to the internal combustion engine.
