Your Boat Smells Like 💩? Fix That Holding Tank Vent

If your boat has that unmistakable “marina bathroom” smell, chances are it’s not the ocean—it’s your holding tank vent. A clogged or failed vent makes odors linger, lets tank pressure build up, and can even cause backflow issues.

The good news? It’s a simple fix. At Old Town Marine, we can swap your holding tank vent line with new hose and fittings, restoring proper airflow. This prevents buildup, helps your tank process waste the way it’s supposed to, and—most importantly—gets rid of that smell that makes guests run for the dock.

Don’t just keep spraying air freshener. If your boat stinks, it’s time to fix the source.
