Abstract
A water jacketed exhaust elbow (10) for a marine propulsion system includes an intake exhaust passage (22) communicating with a discharge exhaust passage (26), a water jacket (27) around the exhaust passages, and a trough member (200) extending longitudinally along a water channel (44) along the exterior of the discharge exhaust passage (26) to guide water therealong to mix with exhaust at the end (42) of the discharge exhaust passage (26). The trough member (200) extends beyond the end tip (42) of the discharge exhaust passage (26) and has a sharp edge (202) providing a clean parting surface for the coolant water and preventing ingestion of water back into the discharge exhaust passage (26).
