T-H Marine Scuppers & Drains: Engineered for Marine Durability
When it comes to keeping your boat's cockpit, transom, and below-deck areas properly drained, T-H Marine has built a reputation for innovative drainage solutions that address the real-world challenges boaters face. T-H Marine's scuppers and drains combine practical engineering with UV-stabilized materials designed to withstand years of saltwater exposure, intense sun, and constant vibration.
Flow-Max Ball Scupper Technology
T-H Marine's Flow-Max ball scupper features a positive sealing design that replaces worn-out flapper scuppers with superior drainage and easy maintenance. The larger exit hole allows 70% more water drainage than its nearest competitor, making it ideal for boats that need rapid cockpit clearing after waves or washdowns. The easy twist-off design makes cleaning debris simple—just twist counterclockwise to remove the ball cavity, clean out, and twist back on. This innovation solves a common frustration with traditional scuppers that require complete disassembly for maintenance.
Flapper Scuppers and Recessed Valves
T-H Marine's Recessed Scupper Valve Drains feature low-profile, weather-proof construction utilizing flexible thermo-plastic that's impervious to marine chemicals and sun damage. These units feature a "curl proof" flapper that maintains sealing integrity even after thousands of open-close cycles. For boats with discharge below the waterline, the Cockpit Scupper Drain is made from high-strength, UV-stabilized polymer and features a check ball for effective sealing against reverse water flow—critical for preventing backflow when backing down on fish or maneuvering in reverse.
Duck Bill and Specialty Drainage Solutions
T-H Marine's thermoplastic duck bill scuppers provide a reliable solution for sealing under water pressure, designed for easy installation over drain tubes with a universal hole pattern for replacing existing flapper scuppers. The brand also offers Large Rectangular Scuppers for vessels requiring maximum drainage capacity, plus self-retaining drain plugs with chemically inert O-rings that won't get lost and provide positive sealing even under high vibration conditions. Whether you're outfitting a center console, maintaining a bass boat's livewells, or upgrading an offshore vessel's cockpit drainage, T-H Marine's scupper and drain systems deliver the durability and performance serious boaters demand.
