We keep our engines super clean and have no leaks or traces of fuel anywhere. I really don't know that there's anything we can do to eliminate it. Our boat is in Florida where molds and mildew abounds...but that's under control. Just the darn DDFS.....

Our engines are under the two aft berths so that's probably part of the problem.

Any tricks for the DDFS?

I've got a motor under the sole as well. The smell does get strong! If you have blower motors for ventilating the compartments turn them on on before turning off the engine and run them a short while after. It helps some.

In every "persistent boat odor case" I know of, the culprit has been the head hoses. Use a warm damp washcloth to scrub each hose individually and smell the cloth. If the odor transfers to the cloth - problem identified. Even if you cannot capture a smell, chances are the hoses are still at fault.

If I replace the hoses, should I replace the vent hose as well?

victory598,

Replace all the hoses connected to the sewage system. They get permiated and the only fix is to replace them all.

Get the best hose you can find made for sewage.

We had a persistent odor problem and replacing the head hoses made a dramatic difference. In addition to good quality marine hose, we also used PVC in certain areas where we had a straightforward lead. As PVC well works in homes, it can serve the same purpose on a boat. Good luck!
