Abstract
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.
Claims13
A marine vessel, comprising an outer drive protection including 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 isolate the at least one outer drive from ambient air surrounding the outer drives;
- wherein the arrangement provides a protective gaseous environment inside the cover;
- wherein the gaseous environment contained within the cover is circulated and maintained at a predetermined atmospheric condition by means of a source of conditioned gas, and wherein the source of conditioned gas is an atmospheric conditioning device comprising at least a dehumidifier arranged adjacent or inside the cover to condition the gas inside the cover.
A marine vessel, comprising an outer drive protection including 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 isolate the at least one outer drive from ambient air surrounding the outer drives;
- wherein the arrangement provides a protective gaseous environment inside the cover;
- wherein the gaseous environment contained within the cover is circulated and maintained at a predetermined atmospheric condition by means of a source of conditioned gas, the cover comprises at least one opening and/or a gas release valve connected to the ambient atmosphere in order to provide a throughflow of the conditioned gas, wherein the conditioned gas is air.
A marine vessel, comprising an outer drive protection including 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 isolate the at least one outer drive from ambient air surrounding the outer drives;
- a humidity sensor for detecting the humidity of the gas inside the cover;
- wherein the arrangement provides a protective gaseous environment inside the cover;
- wherein the gaseous environment contained within the cover is circulated and maintained at a predetermined atmospheric condition by means of a source of conditioned gas.
A marine vessel, comprising an outer drive protection including 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 isolate the at least one outer drive from ambient air surrounding the outer drives;
- a pressure sensor for detecting the pressure inside the cover;
- wherein the arrangement provides a protective gaseous environment inside the cover;
- wherein the gaseous environment contained within the cover is circulated and maintained at a predetermined atmospheric condition by means of a source of conditioned gas.
