Sometimes it just takes time for the odor to completely disappear. If you find and remove the source (sounds like you have) it can take awhile for the smell to disappear from everything in the boat that absorbed it. In our last boat there was about 30 gallons of diesel and seawater sloshing around in the bilge when we first saw the boat, it literally made your eyes water. Even after removing all of the oily water and cleaning the bilge thoroughly we would develop headaches if we were on the boat overnight. We eventually painted the bilge, replaced all the cushions and the headliner before it smelled "clean", but if the boat had been closed up for awhile you would still catch a bit of the smell when you first went in for a couple of years.
