摘要： A divider (25, 22) is integrated into the upper end of an outboard motor exhaust tube (17) so that the exhaust discharging from a pair of engine ports (12a) remains separated for a portion of its downward travel through the tube. The divider separates the exhaust tube itself into multiple individual channels. More specifically, a longitudinally extending vertical plate (25) is disposed within the exhaust tube and extends thereacross. The opposed vertical plate edges are anchored to the vertical exhaust tube walls (18, 19). In the present embodiment, a longitudinally extending cooling tube housing (22) effectively forms part of one of the exhaust tube walls (18) and with the housing itself forming part of the divider.

摘要： A boat drive has a leg formed by three portions, the upper portion passing through the transom opening and may be preassembled with the inboard engine. Lower leg portions are readily detachable from the upper. The leg has a forward and an aft engine cooling water intake ports. A water pump is supplied water via a channel connected to the aft port which joins a forward port, and another channel lead to the water pump. When the leg is tilted up, aft port is out of water but the channels form a water lock where they join to prevent sucking of air through aft port. The leg includes exhaust passageway through propeller hub, and check valve element moves to close exhaust passageway during reverse. Another exhaust outlet is near or above water level and the exhaust passage leading thereto is closed by a water lock which receives water from a water inlet port in the trim tab. A torsion intermediate shaft drives the propeller through a rubber damping and overload-preventing coupling. The coupling is splined separable between separable leg portions. Gear shift mechanism parts disposed below the gears on the propeller shaft are accessible by a removable end closure member which carries a skeg. Gear shift mechanism includes an upright rod connected for up and down movement through a spring-loaded lost motion connection to an actuating lever. A cam member at the lower rod end cooperates with a transmission dog clutch. A spring-loaded detent retains the rod in a neutral position until moved by the lever into drive positions.

摘要： The marine propulsion device includes a lower unit having a gear case normally submerged in water and arranged to discharge engine exhaust gas rearwardly from the rear end into the water exteriorly of the propeller hub. A ring member or thrust ring including a hub mounted on the propeller shaft for common therewith, an annular collar and a plurality of circumferentially-spaced, radially extending spokes or ribs interconnecting the annular collar and the hub serves as a fishline and weed cutter. The annular collar includes an annular outer surface which extends closely adjacent an annular inner surface in the interior of the gear case adjacent the trailing edge of the gear case. In one embodiment, forward migration of the engine exhaust gases along the outer surface of the gear case, which can cause unstable handling of the lower unit, is prevented by an anti-ventilation means including an annular section on the ring member collar located rearwardly of the annular outer surface and rearwardly of the trailing edge of the gear case and having an outer surface tapering radially outwardly from the outer surface of the gear case toward the propeller.

摘要： The marine propulsion device includes a lower unit normally submerged in water, a propeller carried by the lower unit, and an annular shroud surrounding the propeller blades and defining a passageway through which water flows. The shroud, which can be in the form of a Kort-type nozzle for augmenting propeller thrust, has a trailing edge located rearwardly of the travel path of the propeller blade tips. The trailing edge of the shroud includes an annular recess through which either engine exhaust gases or atmospheric air is delivered to ventilate the low pressure area created behind the trailing edge of the shroud during forward movement of the lower unit through water.

摘要： A marine outdrive unit is disclosed in which the outdrive unit is supported substantially on a four-bar linkage. One bar of the four-bar linkage is formed by spaced locations adjacent the transom of the boat on which the outdrive unit is mounted. The second and opposite bar is formed by fixed portions of the housing for the outdrive unit. Pivotal kickup and trim for the unit is provided by the other two bars of the four-bar linkage, one of these being formed in a series of universal joints joining the gear drive, drivingly connected to the marine engine, to the shafting driving the propeller for the marine outdrive unit. The last bar of the four-bar linkage is provided by a hydraulic means which is pivotally attached to the outdrive unit at its piston end and mounted adjacent to the transom. Thus, retraction of the hydraulic piston means causes tiltup of the outdrive unit for either the trim or kickup function. The hydraulic piston means is also pivotally mounted on the transom on an angularly extending axis relative to the vertical so that steering of the outdrive unit may be obtained by movement of the hydraulic piston means, pivotally, relative to this axis.
