One of the 110v power outlets in our 2005 Beneteau 343 shows some black residue and slight disfigurement from a space heater meltdown this winter. I would like to replace it with OEM but have not had any luck locating a vendor. The beneteau website only shows the 220V outlets as a replacement. Any ideas? It is a single outlet with a spring loaded cover. My next move will be to replace it with a standard GFCI outlet, but I'd rather not cut any new holes in the cabin.
