  • 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: 11352937
    Abstract: A marine drive is for propelling a vessel in body of water. The marine drive has a powerhead, a crankcase on the powerhead, and a cooling system that pumps a first flow of cooling water from the body of water through a powerhead cooling conduit for cooling the powerhead and in parallel pumps a second flow of cooling water from the body of water through a crankcase cooler for cooling the crankcase and lubricant in the crankcase. A valve controls the second flow of the cooling water to the crankcase cooler. The valve is normally positioned in a closed position, which inhibits the second flow of cooling water to the crankcase cooler and thereby reduces condensation of water from the lubricant in the crankcase. The valve is moved into an open position upon operation of the powerhead at or above a threshold speed, which permits the second flow of cooling water to the crankcase cooler and thereby cools the lubricant in the crankcase.

  • Patent number: 11352118
    Abstract: A method for controlling propulsion of at least two marine drives on a marine vessel includes monitoring an engine output indicator for each of the at least two marine drives on the marine vessel and detecting whether the engine output indicator for a subset of those at least two marine drives is below an expected value. If so, then an output restriction is imposed on at least one remaining marine drive not in the subset of marine drives, wherein the output restriction reduces an engine output of the at least one remaining marine drive to a predetermined level.
