A device for coupling a propulsor to a marine vessel. A rail is configured for attachment to the marine vessel. A carriage is moveable relative to the rail into first and second positions. A shaft has a first end pivotally coupled to the marine vessel and a second end for coupling to the propulsor. An actuator is configured to pivot the shaft relative to the marine vessel to thereby move the propulsor into and between stowed and deployed positions. A lock is manually operable to fix the carriage in the first position in which the actuator prevents manual pivoting of the shaft and alternatively in the second position in which the shaft is permitted to be manually pivoted.

A stern drive is for propelling a marine vessel in a body of water. The stern drive has a powerhead, a mounting assembly configured to affix the powerhead to the transom, inside the marine vessel, and a drive assembly coupled to the mounting assembly, the drive assembly being trimmable up and down relative to the mounting assembly, the drive assembly comprising a driveshaft and an output shaft which extends transversely to the driveshaft. The drive assembly has a driveshaft housing for the driveshaft and a gearcase housing for the output shaft, wherein the gearcase housing is steerable relative to the driveshaft housing. A universal joint couples the powerhead to the driveshaft so that operation of the powerhead causes rotation of the driveshaft, which in turn causes rotation of the output shaft.

A drive system for a marine vessel including a first housing fixed to an opening in a hull of the marine vessel, and a drive unit arranged inside the first housing. The drive unit is provided with a second housing comprising an electric or combustion drive motor and a marine propulsion system attached to the second housing. The drive system is provided with a parking position in which the marine propulsion system is positioned inside the first housing, a drive position in which the marine propulsion system is positioned outside of the first housing and an intermediate position in which the marine propulsion system is positioned between the parking position and the drive position.

A boat drive for a boat having a boat hull with a bottom. The boat drive includes an underwater pod; an electric motor disposed in the underwater pod, the electric motor driving, via a drive shaft, a propeller attached to the underwater pod; and an electrical supply line for supplying energy to the electric motor. The boat drive further includes an inner tube connected to the underwater pod and displaceably disposed in an outer tube, wherein the electrical supply line is routed through the inner tube. The boat drive further includes a mounting body attachable to the bottom of the boat hull, wherein the outer tube is passed through the mounting body. At least one annular sealing element is disposed between the inner and outer tubes, wherein the at least one annular sealing element seals the inner tube and the outer tube in a radial direction relative to the longitudinal axis of the inner tube.

A marine drive has a propulsion unit, a supporting cradle, a resilient mount that couples the propulsion unit to the supporting cradle, a sound blocking member that extends across an internal gap between the propulsion unit and the supporting cradle, and a cowling system having upper and lower cowlings that cover at least a portion of the propulsion unit and lower cradle covers that cover at least a portion of the supporting cradle. The upper and lower cowlings are separated from the lower cradle covers by an external gap so that the upper and lower cowlings can move along with the propulsion unit and with respect to the supporting cradle and the cradle covers. The sound blocking member blocks the sound which otherwise would emanate from propulsion unit via the internal gap and then from the marine drive via the external gap.

A stern drive is for propelling a marine vessel in water. The stern drive has an upper drive unit with a lower mounting surface; a lower gearcase coupled to the lower mounting surface and a trailing end surface that is angled relative to the lower mounting surface; and a propeller shaft extending forwardly from the lower gearcase and being configured to rotate a propeller for pulling the marine vessel in the water. The upper drive unit and the lower gearcase are configured such that when a forward side of the lower gearcase impacts an underwater obstruction, the lower gearcase is caused to pivot relative to the upper drive unit until the trailing end surface impacts the lower mounting surface, which thereby causes the lower gearcase to completely uncouple from the upper drive unit.
