T-H Marine pioneered the use of the overflow drain tube for boat livewells. The original overflow drain tubes are still the best in the industry. Our tubes provide a very functional way to plumb a livewell. Using our overflow tubes means you only need one hole in the livewell and one fitting to serve as both the overflow and the drain. Instead of reaching into the water and getting wet to pull a drain plug, you simply pull the tube out from the top and draining begins.

NOTE: Any tube can be cut to custom length for boat manufacturers. Specify the desired length by adding it at the end of any part number. For example, to request an 8" length of the ODT-1, the correct part number is ODT-1-8.
These overflow drain tubes feature a threaded end fitting that screws into a threaded thru hull drain. This means of securing the tube assures that the tube will not come out of the fitting in even the roughest conditions. To drain, simply unscrew the tube. A neoprene gasket provides a water tight seal.
