T-H Marine

<h3>About T-H Marine Supplies</h3><p><strong>T-H Marine Supplies</strong> has been one of the most trusted names in the marine accessories industry for over five decades. <a href="/7603-t-h-marine">Founded in 1975 by Bill Huntley in Huntsville, Alabama</a>, the company grew from a small, family-owned operation into a leading manufacturer of boat parts and accessories serving both OEM boatbuilders and the aftermarket. Today, T-H Marine is a proud member of the OneWater Marine family, yet retains the hands-on dedication to quality that has defined it from the beginning.</p><h3>Designed by Boaters, for Boaters</h3><p>What sets T-H Marine apart is its roots. The team behind the brand has always been made up of avid boaters and anglers who understand the demands of real time on the water. That real-world perspective drives an approach to product development centered on practical innovation — solving problems that boaters actually encounter. From pioneering the first commercially available jack plate with the iconic <strong>HI-JACKER</strong>, to patenting improved throttle designs and narrow battery trays, T-H Marine has a long track record of bringing genuinely useful ideas to market.</p><p>Their <strong>ATLAS hydraulic jack plate</strong> became the dominant choice among professional bass fishermen and OEM boatbuilders alike. By the 2014 BASSMASTER Classic, ATLAS jack plates were found on the overwhelming majority of boats running hydraulic jack plates — a testament to the product's reliability and performance credentials.</p><h3>A Comprehensive Marine Product Lineup</h3><p>T-H Marine's catalog spans virtually every system on a modern recreational boat. Their product categories include jack plates, <a href="/7603-t-h-marine-trim-and-tilt-units-202681">trim and tilt units</a>, trolling motor accessories, plumbing and drains, LED lighting, hatches and deck plates, livewell aeration systems, rigging accessories, battery trays, and rod storage solutions. Whether you're rigging a tournament bass boat or fitting out a pontoon for family outings, T-H Marine likely has a product engineered for the task.</p><p>The brand supplies products to virtually every recreational boat manufacturer in the United States — found on bass boats, pontoon boats, runabouts, ski boats, offshore fishing boats, flats boats, aluminum fishing boats, and center console boats. Their aftermarket parts are available through marine dealers, retail chains, and online retailers nationwide.</p><h3>Innovation With a Proven Track Record</h3><p>Throughout their history, T-H Marine has continued to expand into new product niches while maintaining leadership in core categories. They introduced the first remote livewell drain valve, developed pioneering rod storage tube systems for boat compartments, and grew their lighting line to include waterproof courtesy and livewell lighting. Their <a href="/7603-t-h-marine-trim-and-tilt-units-201108">CMC tilt and trim systems</a> represent the same durability-first philosophy — built to handle the rigors of fresh and saltwater use over thousands of hours of operation.</p><p>With over 700 products in their lineup and a half-century of marine industry expertise, T-H Marine remains a go-to source for boaters who demand aftermarket accessories that match or exceed OEM standards.</p>

Good job guy great parts

Saved some money here buying sunshade for my new car. Thanks...! 8-)

Great place to shop. My brother and I race for cars and they were by far the cheapest place for our car cover by about 40 bucks!

So far, so good. Best price I found. Very reasonable shipping. Parts were loose packed and rattled around a bit but nothing damaged. The hole for the EGR in the header was just a small hole and I had to drill it out. There were no instructions or any do

Awesome!

Autoplicity was easy to deal with, and the price was hard to beat. Will use again.
