An outer drive protection arrangement is attachable to a marine vessel while not immersed in water. The arrangement comprises a rim portion arranged in contact with at least a transom surface and surrounding at least one outer drive and a protective cover attached to the rim portion and enclosing a volume encompassing the at least one outer drive, in order to provide a protective gaseous environment inside the cover. The environment contained within the cover is circulated and maintained at a predetermined atmospheric condition by means of a source of conditioned gas.

A propulsion unit for a marine vessel is adapted to receive power from at least one power supply unit. The propulsion unit includes a stationary part adapted to be mounted to a hull of the marine vessel, and a movable part comprising one or more thrust generating devices adapted to transform the received power into a thrust by acting on water carrying the marine vessel. The propulsion unit is adapted to receive exhaust gases from at least two internal combustion engines, wherein the movable part is adapted to release the exhaust gases into the water.

A gear housing for an aquatic vessel is adapted to be attached at an attachment site to an underside of a hull of the aquatic vessel. The gear housing includes at least one weakened region adapted to yield when the gear housing is rotated at the attachment site following an impact. A breakaway safety system includes such a gear housing, and a fracturable member for attaching the gear housing to the hull at the attachment site, wherein the weakened region is adapted to yield such that the fracturable member fractures. An aquatic vessel includes such a gear housing or such a breakaway safety system.
