  • Marine propulsion system with fuel line cooler
    Patent number: 4875439
    Abstract: A fuel line cooler (34) is provided for a marine propulsion system (2) having a water cooled internal combustion engine (4) in a heat retentive compartment (5). The fuel line cooler (34) has an inlet (36) in communication with the source (14, 12) of cooling water for the engine (4), and has an outlet (38) for discharging water. The fuel line cooler (34) is cooled by sea water during running of the engine (4). Upon turn off of the engine (4), the cooled water in the fuel line cooler (34) is in heat transfer relation with the fuel and prevents vaporization and or spewing of the fuel.
    Type: Grant
    Filed: March 14, 1989
    Date of Patent: October 24, 1989
    Assignee: Brunswick Corporation

  • Exhaust elbow trough
    Patent number: 4845945
    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).
