I found the marine head toilet odor us usually caused by the soup that forms on the salt water feed line to the toiletcwater inlet. You will see a blackish water firstxenter the bowl when flushed. Especially if unused for a long time. Be sure to give each toilets long flush when you first enter the boat. Also add a 2 inch pipe "T" manifold to the feed hose with a screw cap. Insert chlorine tablets. This will allow some chlorinated feed water to back drain into the feed line. These lines are especially problematic if they have a long level feed run. You can also buy biocide treated feed hose. Its expensive.
