  • Patent number: 5109668
    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.

  • Patent number: 4866934
    Abstract: A marine drive exhaust system (10, 12, 14) is provided with resilient, shaped rubber O-ring seals (20, 74) between facing surfaces (16, 18) of the exhaust manifold (10) and exhaust elbow (12), and the facing surfaces (70, 72) of the exhaust elbow (12) and the exhaust pipe (14). Each of the shaped O-ring seals has an inner peripheral rib (22, 76) extending peripherally around the exhaust passage and generally conforming to the shape thereof and being spaced laterally between the exhaust passage and the peripheral water passages. Each of the shaped O-ring seals has an outer peripheral rib (28, 82) extending peripherally around the water passages and spaced laterally outward of the inner rib by a gap (30, 84) through which the water passages extend.

  • Patent number: 4062401
    Abstract: A plurality of segmented components are arranged to form a fixed radial heat exchanger. Each segment is an independent heat exchanger having a core of fluid tubes and air flow corridors between the tubes. Air flow is maintained through the heat exchanger by means of a propeller type fan mounted coaxially with the heat exchanger.
