#1 CHOICE FOR LIVEWELL DRAIN TUBES IN THE INDUSTRY. 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.

Outside diameter of 1 1/2" overflow drain tube boot and tube is 1 5/8", outside diameter of 1 1/8" overflow drain tube boot and tube is 15/16"

Push-in Tubes

These overflow drain tubes feature a tough, flexible vinyl plastic end with a standpipe of white PVC tubing. To use, simply insert vinyl end into the opening of thru-hull fitting. To drain livewell or baitwell, simply remove. This unique drain tube seals much better than any other overflow on the market and removal is much easier.

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. **THIS IS NOT AVAILABLE FOR ONLINE ORDERS.

Drain tube replacement caps

I second my friend stephen G - I also have not yet received anything 3 weeks later. Hope to receive them soon. Still only showing “order placed.” 7/29/2023 - Order #TH54183912 - seems like more than 8-10 business days to me.

I’m unable to write a review at this time as I have not received my order #TH54183867 that was placed on July 28, 2023. I am writing this review on August 18, 2023, 21 days later. I hope I receive my order soon!
