T-H Marine Flow-Max™ Ball Scupper - Clear

The T-H Marine Flow-Max™ Ball Scupper in clear is an essential drainage solution for any boater serious about deck maintenance and water management. This product is ideal for center consoles, cabin cruisers, and deck boats, helping to prevent water pooling that can create safety hazards and accelerate corrosion.

Engineered by T-H Marine Supplies, the Flow-Max™ Ball Scupper features a one-way ball valve mechanism that allows for controlled, gravity-fed drainage while preventing backflow during rough seas. Its clear body design enables easy visual inspection of water flow and ball movement, ensuring proper functionality. Compact and lightweight, it integrates seamlessly into tight spaces on your vessel.

Saltwater and freshwater anglers, cruising boaters, and commercial operators will find this drainage system particularly beneficial. Installation typically involves through-hull mounting in low-point areas where water accumulates, such as cockpit corners or transom-mounted live wells. The transparent design allows for verification of drainage activity without dismounting the scupper.
