T-H Marine ODT-2 Overflow Drain Tube - 18 Inch Straight Push-In Tube with Screen, Fits 1-1/2 Inch Thru-Hulls

The T-H Marine ODT-2 is an 18 inch straight overflow drain tube built to fit all T-H Marine 1-1/2 inch thru-hull fittings. It is a push-in style tube that combines the overflow and drain function of a livewell or baitwell into a single fitting, so the boat only needs one hole and one thru-hull to handle both jobs. The design pairs a tough, flexible vinyl boot end with a rigid white PVC standpipe. To install, the vinyl boot is simply pushed into the opening of the thru-hull fitting for a snug, watertight seal with no tools, clamps, or adhesive required. To drain the livewell or baitwell, the tube is pulled straight up and out from the top, so there is no need to reach into the water or pull a plug from underneath.

The outside diameter of the tube and boot is 1 5/8 inches, sized to seat securely in a 1-1/2 inch thru-hull opening. The tube ships with a screen installed to help keep debris out of the drain line, and the screen can be trimmed to set a custom tube length for the installation. Construction is marine grade PVC throughout, giving the tube resistance to UV exposure, chemicals, and the general wear of freshwater or saltwater use. This is a straight-tube design intended for draining through the floor of the livewell or baitwell; T-H Marine also offers a 90 degree version, the ODT-290, for side wall draining installations.
