  • Devices and methods of making devices for coupling propulsors to marine vessels
    Patent number: 11932369
    Abstract: A device for coupling a propulsor to a marine vessel. The device includes a mounting bracket configured for attachment to the marine vessel. A support frame has a carriage and is configured for the propulsor to be coupled thereto, where the carriage is configured to slidably engage with the mounting bracket into a fixed position. A member is manually engageable to prevent the carriage from sliding out of the fixed position. The propulsor is coupled to the marine vessel by sliding the carriage into the fixed position and engaging the member, where the propulsor is operable to propel the marine vessel in water when the carriage is in the fixed position, and where the propulsor is configured for decoupling from the marine vessel by disengaging the member and sliding the carriage out of engagement with the mounting bracket.
