T-H Marine Livewell Accessories: Engineering Fish Survival on the Water

For tournament anglers and serious fishing enthusiasts, a livewell is only as good as the accessories keeping it running. T-H Marine has been engineering dependable marine accessories since 1975, and their livewell lineup reflects decades of on-the-water insight. From aerators and overflow drain tubes to complete plumbing kits, T-H Marine's livewell accessories are purpose-built to maintain optimal water conditions and maximize fish survival—whether you're weighing in at a local tournament or spending a long summer day on the lake.

A Legacy Built Around Keeping Fish Alive

T-H Marine's approach to livewell accessories goes beyond simple hardware. The brand understands that water quality, oxygenation, and circulation are all critical factors in fish health, particularly in warm weather when dissolved oxygen levels drop. That philosophy drives every product in their livewell lineup.

Among their most recognized livewell solutions is the Max-Air™ Livewell Venturi Aerator, designed to maximize water agitation and oxygen infusion without relying on complex motorized components. The venturi design uses water pressure to pull air into the stream, creating an effective aeration effect that keeps bait and catch active and healthy. The Max-Air™ is available with a face plate and tubing sized for standard 3/4" hose connections, making it a straightforward upgrade or replacement for most boat livewells.

T-H Marine also offers a range of overflow drain tubes—available in straight push-in and screw-in configurations, in lengths of 12" and 18"—that regulate water levels inside the livewell tank. Properly functioning overflow tubes prevent overfilling while maintaining the consistent water depth fish need. Some models include integrated screens to block debris from re-entering the system, a small but important detail for long days on the water.

Complete Plumbing Kits for Full Livewell System Builds

For boaters looking to upgrade or build out a livewell system from scratch, T-H Marine's Livewell Plumbing Kits bundle the key components—aerator heads, directional tees, and overflow drain accessories—into a single, cohesive package. These kits are engineered for compatibility with standard livewell tanks and feature a 90-degree directional aerator head for current creation, which helps circulate water throughout the well and distribute oxygen evenly.

T-H Marine's EZ Pump Advanced Water Pick-Up System also addresses one of the most common livewell challenges: maintaining water flow to the aerator pump while the boat is on plane and underway—a scenario where standard intake systems often struggle. It's this kind of practical, problem-solving engineering that has made T-H Marine a staple on fishing boats across the country.

Trusted by Anglers, Used on Virtually Every U.S. Boat

T-H Marine's products are found on virtually every style of recreational fishing boat built in the United States—from bass boats and flats boats to aluminum fishing boats and center consoles. Their livewell accessories are no exception, offering reliable, marine-grade construction engineered to handle the demands of both freshwater and saltwater environments. For anglers who take fish care seriously, T-H Marine's livewell accessories represent a trusted, well-proven solution.
