Hot smell in head of boat. It is not the the plug in recepticle. Walls do not feel hot? Any ideas?

Question

We did use a new toilet chemical could it be a chemical reaction?

The boat is a 2004 320 Sea Ray (not old)

Answer 1

I would suspect the chemical toilet is giving you a smell you are not used to.

Answer 2

It could be the chemicals. But since the head is a notoriously damp place, check all the switches and lights and other electrical fittings. There could be a bit of corrosion that is causing resistance and the odor.
