ABSTRACT:
A marine exhaust assembly (10) includes a manifold portion (14), an elbow portion (24), a water jacket portion (38), and exhaust runner walls (40, 42, 44, 70, 72, 74, 76, 78, 80), providing a smooth continuous transition of exhaust gas flow from intake exhaust passages (16, 18, 20, 22) in the manifold portion (14) to transfer exhaust passages (26, 28, 30, 32) in the elbow portion (24) around a bend (34) to a discharge exhaust passage (36), minimizing turbulent flow of exhaust through the manifold portion (14) and elbow portion (24). Each transfer exhaust passage has its own water supply inlet (96, 98, 100, 102) at the upstream end of the respective intake exhaust passage. An upper vent includes a steam outlet opening (120) in the water jacket at the high point of the elbow portion, and a steam exhaust channel (122) extending along the top exterior of the water jacket portion in a raised bead (124) above and parallel to an upper water flow passage (126) and directing steam to the end of the discharge exhaust passage to mix with water and exhaust thereat. Wall supports (150, 152, 154) assist in directing cooling water up through the water jacket to the top of the elbow bend, and also prevent wall collapse during lost foam stainless steel casting.
