2003 Champion 206, on the starboard side by the cranking battery there is a black plastic box with a 20A push button breaker sticking out of it, came from the factory installed. The wires going into the box, which seems sealed, are fairly small, maybe 10 gauge or so. What is this breaker for?
I know that it is not for the automatic bilge because that has a waterproof fuse holder nearby.
The breaker is rusted stuck and I would like to replace it but 20A breakers aren't very common, I can get a 25A fairly easy though
