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>
