TH Marine - Aeration & Livewell Accessories


Max-Air™ Livewell Venturi Aerator Kit

Max-Air™ Venturi Livewell Aeration System

Independent marine biologist testing shows that this type venturi livewell fitting is the most efficient aeration system available.

  • The venturi system draws fresh air from outside the livewell and injects tiny air bubbles into the water flowing into the livewell.
  • With the aerated water entering the well at a lower level than with traditional spray heads, the entire well is more thoroughly aerated.
  • The reduced restriction of this fitting allows more water to flow from the pump than traditional spray heads.
  • The faceplate inlet can be mounted anywhere above the waterline (exposed or concealed).
  • System requires 1/8" tubing (speedo tubing is recommended).

Livewell Overflow Drain Tubes


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.
  • Functional and economical overflow drain tube
  • All marine grade PVC construction for long life
  • Sure sealing of livewell / baitwell drainMakes draining livewell / baitwell easier than a plug tube
  • Come with screen loose, so they can be cut to best length
  • Straight tubes for draining thru floor, 90 degree tubes for draining thru side wall


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.

These overflow drain tubes feature a threaded end fitting that screws into a threaded thru hull drain.

To drain, simply unscrew the tube until the drain holes in the threaded fitting are exposed. A neoprene gasket provides a water tight seal.
