Mark's theory about saltwater settling on that side of the boat (probably alongside stringers) from the leaking exhaust fitting seems the most probable. As for other theories, the holding tank is at the other end of the boat, and there is no propane in the vicinity. Even if there was a propane leak that settled into the bilge, it would not have been so localized on just the starboard side away from the bilge(s). And the batteries with a new smart charger are in the engine room and far removed from the small area that smelled.
Appreciate the ideas, though. Thanks!
