Along with that you might also want to try one of those deodorizers in a container that you leave open.That would certainly make sense. I have used Hylomar on many applications. Works very well. Never gets hard. However, never used it in an enclosed space.
Perhaps I could have made a better choice for sealing screw holes in the sump area.
I am going to remove the sump, clean off all the sealant, and let the area sit open for a few days to see if that is the source of the fumes. Since the boat is sitting on a trailer at my house, it is the perfect time to figure out this mystery.
