Sea Ray

I have a 2003 Sundancer 380 that has a vent cover on the starboard bow that is deteriorated. I can't locate one at any Marinas in the area or on line so far that matches the original one. Any suggestions where I could look?

I just purchased my first Sea Ray cruiser. I have a 2003 380  Sundancer and I am having problems with the gauges on the fresh water and the gray water tanking reading the levels. When I push the fresh water gauge all the levels light up all the time....
