  • Patent number: 11459074
    Abstract: A method is for making a marine drive for propelling a marine vessel in water. The method includes providing a gearcase; installing a propeller shaft assembly that extends forwardly from the gearcase; coupling front and rear propellers to the propeller shaft assembly, forwardly of the gearcase, such that rotation of the propeller shaft assembly causes rotation of the front and rear propellers, respectively, which thereby propels the marine vessel in the water; and reducing deleterious effects of cavitation on the gearcase by the combination of forming the gearcase with a wide trailing end portion, in particular to maintain pressure alongside the gearcase, and configuring the front and rear propellers so that the front propeller absorbs more torque/thrust load than the rear propeller during said rotation.

  • Patent number: 11459076
    Abstract: A method for controlling a valve to disengage a gear in a transmission. The method includes reducing, after receiving a request to disengage the gear, a current supplied to the valve from a starting to a first current. The method further includes counting a first elapsed time since the valve was reduced to the first current, comparing the first elapsed time to a first wait time, and increasing the current supplied to the valve to a second current once the first elapsed time exceeds the first wait time. The method further includes counting a second elapsed time since the valve was increased to the second current, comparing the second elapsed time to a second wait time, and reducing the current supplied to the valve to a third current once the second elapsed exceeds the second wait time. The valve is closed when the current is the third current.

  • Patent number: 11427290
    Abstract: An anchor rescue system includes an improved slider assembly 200 and retriever assembly 300 allowing for secure attachment as the retriever assembly is lowered upon an anchor line to attach to the slider assembly. Once attached, the retriever assembly pulls upon the slider assembly with the slider assembly attached to a tether chain 210 with the tether chain attached to a lower portion of the anchor, such as crown, causing the anchor to move upwardly in a relative horizontal position. The system frees trapped anchors without need for floatation devices.

  • Patent number: 11358698
    Abstract: A method for synchronizing shifting of transmissions across marine propulsion devices. The method includes receiving a signal to shift the transmissions and identifying a predetermined shifting time for each of the transmissions, where the predetermined shifting time represents an elapsed time between starting the shifting and completing the shifting. The method further includes comparing the predetermined shifting times to determine a longest shifting time, calculating for each of the transmissions an offset time that is a difference between the corresponding predetermined shifting time and the longest shifting time, and sending a signal to start the shifting of each of the transmissions after waiting the offset time for that transmission such that the transmissions all complete the shifting at the same time.

  • Patent number: 11358694
    Abstract: An oar apparatus configured to remain submerged under water during the power stroke and the return stroke. The oar apparatus has a sheath and a shaft rotationally disposed within the sheath. An oar blade is affixed to the shaft, such that the oar blade is rotational relative to the sheath. The oar blade has a deployed orientation, in which the oar blade is substantially perpendicular to the movement direction of the vessel, and a feathered configuration, in which the oar blade is substantially parallel to the movement direction of the vessel. The oar blade is asymmetrical relative to the center axis of the shaft, such that resistance of the water exerted onto the oar blade creates a first moment urging the oar blade into the deployed orientation during the power stroke and a second moment urging the oar blade into the feathered orientation on the return stroke.
