摘要： A propeller assembly includes an interchangeable drive sleeve, an inner hub, a biasing member forcing the drive sleeve into contact with the inner hub, and a propeller including an outer hub in which the drive sleeve and inner hub are inserted. In an exemplary embodiment, the drive sleeve includes a plurality of teeth that engage a plurality of teeth on the inner hub. The spring is configured to permit the drive sleeve to move axially away from the inner hub upon the occurrence of a sufficient torque and allow the drive sleeve to rotate relative to the inner hub. A bore extends through drive sleeve, and a plurality of grooves are in an inner diameter surface of the drive sleeve bore. These grooves are configured to mate with splines on a propeller shaft. The inner hub includes a plurality of keys and the outer hub includes a plurality of complimentary keyways to limit relative movement between the inner hub drive flange and the outer hub.

摘要： An operator-actuated inlet grate clean-out mechanism which can be actuated by pushing and pulling a cable or rotating a shaft from the driver's seat of a boat. A weed wiper which is arranged to push weeds off of a pivotable cantilever-tine inlet grate as the wiper travels along the tines and toward the aft tips of the tines. As the wiper sweeps along the inlet grate tines, it bears against the inlet grate and causes the grate to swing downward to a position where the aft tips of the cantilever tines are spaced from the pump jet housing. Because the weeds wrap and ball around the inlet grate, they also slide off easily when pushed or dragged by the sweeping wiper bar.

摘要： 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.

摘要： A stern drive system having an outdrive generally disposed downstream relative to water flow aft a transom of the boat is configured to be rotated about a generally horizontal axis to impart a desired trim or tilt to the drive system. A tilt-trim subsystem assembly is affixed to the outdrive and has one respective end thereof configured to pivotally receive an anchor pin supported by the outdrive. The assembly includes at least one cylinder having one end thereof connected to another anchor pin so that when the cylinder is actuated by a circuit therein the outdrive and the tilt subsystem assembly are rotated about the generally horizontal axis during tilt maneuvers. A housing is provided to shield the tilt assembly and configured within the footprint of the outdrive to avoid resistance to water flow. Additionally, the housing may be configured to visually shield the tilt assembly from observers.

摘要： A propeller including, in one embodiment, a flare having a sinusoidal, or tulip, shape is described. The flare is located at a trailing edge of the propeller, and the sinusoidal flare shape of the propeller trailing edge has reduced stresses as compared to stresses associated with known flare rings. Specifically, stress is reduced in the sinusoidal flare shape due to smooth trailing surfaces and the uneven edge of the flare. As a result, and during fabrication, potential for cracking the trailing edge of the flair is reduced. In addition, the flare has greater strength as compared to at least some known flare rings in that stresses are more evenly distributed along the tulip shaped trailing edge.
摘要翻译：在一个实施例中，包括具有正弦或郁金香形状的火炬的螺旋桨被描述。火炬位于螺旋桨的后缘，与已知的喇叭环相关的应力相比，推进器后缘的正弦曲线形状具有减小的应力。具体地说，由于光滑的后表面和喇叭口的不均匀边缘，正弦曲线形状的应力减小。结果，并且在制造期间，削弱了天赋后缘的可能性。此外，与至少一些已知的喇叭环相比，耀斑具有更大的强度，因为应力沿着郁金香形后缘更均匀地分布。
