Abstract: A flushing accessory for connecting a supply of domestic fresh water to the cooling jacket of a marine outboard engine for the purpose of flushing saline residue therefrom. The accessory includes a conventional “earmuffs” assembly which self-adheres to the lower unit of the outboard engine once installed thereon and a long handle enabling the accessory to be installed from within the boat. The handle is hollow, and conducts water from the domestic supply to the “earmuffs” assembly. A connector rigidly and permanently attaches the “earmuffs” assembly to the handle in an orientation such that the axis of the handle is offset from the “earmuffs” assembly. The connector is configured such that a short connector hose conducting water from the handle to the “earmuffs” assembly is disposed in close proximity to the accessory, and is not obliged to form a severe bend.
