摘要： A shutter valve construction for the exhaust system of a marine engine that discharges exhaust underwater. The valve construction includes an adaptor having an annular body that is adapted to be engaged in the end of an exhaust pipe. Opposite sides of the body are provided with outwardly projecting bosses which are received within holes in the exhaust pipe to position the adaptor relative to the pipe. The valve construction also includes a butterfly-type shutter valve that consists of a pair of valve members which are hinged to a hinge pin that is removably connected to the adaptor. To connect the valve to the adaptor, the ends of the hinge pin extend into opposed openings in the body of the adaptor and receive resilient grommets.

摘要： A sea water pump (130) for a marine propulsion system includes a housing (130) having a generally cylindrical pumping chamber (134) defined by a generally cylindrical sidewall (136) extending axially between opposite end walls (138 and 140). A multi-vaned rotary impeller (44) in the chamber is driven by an impeller shaft (28) extending axially into the chamber through one of the endwalls (40). An intake port (146) at the other endwall (140) has a first branch (148) providing radial flow (170, 172) into the chamber, and a second branch (154) providing axial flow (178) into the chamber. A discharge port (158) has a first branch (160) receiving radial flow (174, 176) out of the chamber, and a second branch (166) receiving axial flow (180) out of the chamber. The housing (132) is an integrally molded one-piece cup-shaped unit including the cylindrical sidewall (136) integral with an end cap (144) providing a flat inner wall wear surface (140) providing the noted endwall engaging an axial end (50) of the impeller in sealing sliding relation.

摘要： A conduit is configured to facilitate the assembly of a gear case to a driveshaft housing of a sterndrive marine propulsion device while maintaining the proper position of the conduit and assuring proper sealing when the gear case is attached to the driveshaft housing. An alignment protrusion extends from a central portion of the conduit to facilitate the proper positioning of the conduit in relation to the driveshaft housing prior to the attachment of the gear case to the driveshaft housing. A flared portion of a lower end of the conduit is shaped to facilitate the insertion of an outlet of a water pump into the conduit, wherein the water pump is attached to the gear case prior to assembly of the gear case to the driveshaft housing.

摘要： A transmission for a marine propulsion device is provided with a movable member that responds to relative rotational movement between it and a driving shaft with an axial movement relative to the driving shaft and to a driven component. This axial movement is directed against one of two spring components which resist the axial movement. During the compression of either of the spring components, rotation of the driven component is non-synchronous with the driving component during a brief period of time. Also, the driven component is decoupled at least partially from torque transmitting relation with the driving component during the axial movement of the movable member relative to the driving and driven components.
