T-H Marine

<h3>About T-H Marine</h3><p>Since 1975, T-H Marine has been one of the most respected names in the recreational boating industry. <strong>Founded in Huntsville, Alabama</strong>, this family-owned company was built by boaters and anglers who understood firsthand what the water demands. That passion for the sport drives every product they design — from the transom to the helm — and it shows in the breadth and quality of their lineup.</p><p>T-H Marine's legacy is one of genuine innovation. The company revolutionized recreational boating with the first-to-market, full production jack plate — a product category they essentially created. Their <a href="/7603-t-h-marine-jack-plates-200590">jack plates</a> remain the cornerstone of their catalog, and for good reason: T-H Marine is a leader in the hydraulic jack plate market, with its products being used by almost all OEM boatbuilders and by more pro-fishermen than all other companies combined. From the iconic <strong>HI-JACKER&trade;</strong> manual plates to the sophisticated <strong>ATLAS&reg;</strong> hydraulic series, the lineup covers outboards of virtually every horsepower class.</p><p>Performance on the water goes beyond just motor positioning. T-H Marine's <a href="/201071-tilttrim-motors-t-h-marine-7603">tilt/trim motors</a> and <a href="/7603-t-h-marine-trim-controls-201109">trim controls</a> give boaters precise command over their outboard's angle at any speed. The brand also introduced the first foot-operated trim switch — the HOT TRIM — providing a safety feature that allows boaters to keep both hands on the wheel when running at higher speeds. That same philosophy of hands-on safety extends to their steering-wheel-mounted trim control units, which put adjustment right at the driver's fingertips.</p><p>Getting a clean, functional helm setup on an aluminum or Jon boat has always been a challenge, which is where T-H Marine's <a href="/7603-t-h-marine-steering-throttle-mounts-201012">steering &amp; throttle mounts</a> make a real difference. Their steering console mounts add steering control and a cleaner helm setup, designed to be adaptable to most aluminum or fiberglass boats. Pair that with their multi-purpose gauge mounts and you have a complete, organized cockpit without a custom fabrication project.</p><p> T-H Marine produces thousands of products across many categories, including outboard motor mounts, outboard tilt and trim, access hatches, deck plates, livewell aeration, plumbing fittings, battery trays, fishing rod holders, boat lights, rigging accessories, trolling motor accessories, and pontoon boat parts. Whether you&apos;re rigging a new bass boat, upgrading an older aluminum fishing rig, or outfitting a center console for coastal fishing, T-H Marine has the hardware to get it done right.</p><h3>Why Boaters Trust T-H Marine</h3><ul style="list-style:disc"><li>Over 45 years of marine innovation and manufacturing experience</li><li>Pioneer of the outboard jack plate — a category-defining invention</li><li>Products trusted by professional tournament anglers and OEM boatbuilders alike</li><li>Extensive range covering performance, rigging, plumbing, lighting, and helm accessories</li><li>Designed by boaters, for boaters — from a team that actually spends time on the water</li></ul>

Product Details

The T-H Marine HYDRA™ Livewell Pump (PMP-LWL8-DP) is a professional-grade 800 GPH livewell circulation pump engineered for serious anglers who demand consistent performance and easy serviceability. Backed by 4,000 hours of rigorous testing, this 12V pump is built to deliver reliable livewell water circulation in demanding marine environments.

A standout feature is the anti-airlock design, which ensures dependable restarts even when air is trapped in the line — a common issue that sidelines lesser pumps. The precision-balanced motor paired with a 316 stainless steel motor shaft minimizes vibration and noise while resisting corrosion over the long haul.

Servicing the HYDRA is faster and easier than traditional pumps thanks to the dual-lock cartridge system, which allows full motor removal without disconnecting any hoses or plumbing. The removable long nozzle adds further convenience for quick maintenance access. Stator vane technology optimizes flow efficiency, ensuring you get the full 800 GPH output your livewell needs.

This pump also doubles as a wash-down source via its dedicated secondary outlet, and includes an integrated sealant channel to prevent leaks at the installation point. Both short and long threaded intake options are supported for flexible installation configurations.

Key Specifications:

  • Flow Rate: 800 GPH
  • Voltage: 12V DC
  • Amp Draw: Approx. 4A
  • Fuse Size: 5 Amp
  • Installation Hole: 1-1/16"
  • Nozzle Style: Long Nozzle
  • Motor Shaft: 316 Stainless Steel
  • UPC: 733572258288

Key Features:

  • Anti-airlock design for reliable restarts with air in the line
  • Dual-lock cartridge for fast motor removal without disconnecting plumbing
  • Precision-balanced motor reduces vibration and noise
  • 316 stainless steel motor shaft for long-term corrosion resistance
  • Stator vane technology for optimized flow efficiency

The HYDRA Livewell Pump meets all required industry standards including ABYC, ISO 8846 Marine, and U.S. Coast Guard regulations (33CFR-183.410 and 33CFR-183.425), making it a code-compliant upgrade or replacement for any fishing boat livewell system.

Great price. Great product. Very fast shipping. No complaints at all.

Extremely fast shipping,safe and proper packaging. happy to get the last one available in the U.S .hope it preforms as advertised.

Fast shipping

Quick and easy. Last place to have this in stock.

I'm waiting on my refund. I was not happy that I couldn't talk to a real person regarding my return and my repurchase of the correct prop that I needed. So , if I get my total refund without a huge restocking fee(since the prop is new in original packaging and I bought another prop that is the correct size) then I will be extremely satisfied.

Great! Equal to any

Shipping was a bit expensive. Sure you folks didn't have anything to do with that. Would use you again.

Great prices
