Abstract: Various technologies described herein pertain to interconnect systems for electrical cables. An interconnect system can include a connector, an adapter ring, and a backshell. The connector includes a threaded distal coupling portion. The adapter ring includes a threaded proximal coupling portion and a non-threaded distal coupling portion. The backshell includes a proximal coupling portion and a port. The threaded proximal coupling portion of the adapter ring and the threaded distal coupling portion of the connector can be mechanically attached. Additionally, the proximal coupling portion of the backshell and the non-threaded distal coupling portion of the adapter ring can be mechanically attached. A wire bundle can enter the backshell through the port, pass through the adapter ring, and terminate at the connector. A shield that encloses the wire bundle can terminate at the backshell such that an end of the shield is positioned around an outer surface of the port.

Abstract: An apparatus is for supporting a marine engine and has a transom bracket having a body section, a head section extending transversely relative to the body section, a neck section disposed between the body section and the head section, and a transition portion along an inside surface of the neck section. A reinforcement member is connected to the neck section and relieves tensile stress on the transition portion when the transom bracket supports the marine engine.

Abstract: A marine propulsion drive unit is provided with two energy absorbing structures, one comprising a crushable or deformable nose cone or leading edge of a driveshaft housing and the other comprising a frangible interface that allows the drive unit to separate from the hull of a marine vessel. The crushable or deformable nose cone is configured to absorb energy at relatively low impact velocities with submerged structures and the frangible interface is configured to absorb energy and then detach from the hull of the marine vessel at higher impact velocities.

Abstract: A marine propulsion system is configured to allow many different combinations and interconnections between three internal combustion engines, three generators, two motors, two clutches, two marine propulsion devices, and an electrical storage device. By appropriately interconnecting these devices in advantageous combinations, energy consumption can be reduced, operational efficiency of the engine can be improved, and redundancy can be provided in the event that one or more components are disabled.
