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>

Product Details

The T-H Marine SDP1DP is a 5-5/8" screw down deck plate designed to provide reliable access to storage compartments, livewell systems, and bilge areas on boats and marine vessels. This economical access solution features a threaded cap design that screws securely into place, creating a water-resistant seal.

Key Features:

  • 5-5/8 inch outer diameter for standard marine applications
  • Durable black poly construction resists UV rays, corrosion, and marine environment exposure
  • Matte finish reduces glare and complements most boat interiors
  • Screw down design provides secure closure at a lower cost than screw-out style plates
  • Super tough polymer material withstands impacts and heavy use
  • Easy installation with basic tools

An affordable alternative to premium screw-out deck plates, this access port delivers dependable performance for recreational and fishing boats. The threaded design ensures the cap stays in place during operation while remaining easy to remove when access is needed.

Unbelievably fast shipping

Thumbs up

I appreciate the fast delivery time!

Arrived as described

On time and fast

Website was easy to navigate and shipping was very quick.

Found what I needed at price that is OK.

Faster shipping than I expected. Easy order process. The ignition switch was my problem and Autoplicity part was exactly what I needed at a price better than anyone else had, with shipping included. I will definitely look to them again when I need any more parts for my Monte Carlo SS.<br>Only slight negative would be it took a few days to get an email with tracking number so I would know when my part would come. But once I got it, found it was coming sooner than I originally thought, which was great.

I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for. Items were ship out in 2 business days from the original manufacturer. Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

Autoplicity was the cheapest place I could find for my Turbosmart Eboost2. I ordered my controller yesterday and they promptly gave me a receipt and a normal time frame for delivery. Today I got the tracking number and at lunch I got an email saying order complete and delivered. This was an awesome experience and I will definitely be using them next time i'm in the market for a similar product.

Great price, and quick processing of my order. Will use again.

Easy to use website

Simple and fast checkout

So far so good. No description about which brake pads were for the front and which were for the back though. I haven't had a chance to install these yet but shipping was fast.

Smooth transaction

Great price, very helpful tech support,thanks will buy again<br><br> Chris

Fast and easy had what I needed. Also could not find what I was looking for any where but here. Thanks

Good

I'm a little concerned. The Fabtech part number doesn't match the correct description. I need the impact tube rear mount not the bushing kit. I talked to a representative and he said if I used the Fabtech number I would get the correct part.
