AFI

<h3>About AFI – Marine-Grade Wiper Systems Built to Last</h3><p>For boaters who refuse to compromise on visibility and reliability, <strong>AFI</strong> — sold widely under the <strong>Marinco</strong> name — stands as one of the most trusted manufacturers of marine windshield wiper systems in the world. Whether you're navigating coastal inlets, open ocean swells, or freshwater lakes, AFI's product lineup is purpose-built to endure the relentless punishment of saltwater, UV exposure, and extreme weather.</p><p>AFI's heritage in marine electrical and wiper technology has made it a go-to brand for both original equipment manufacturers and aftermarket boat owners alike. <a href="/7226-afimarincoguestnicrobep">AFI/Marinco</a> products are found as factory-installed components on vessels from brands like Sea Ray, Tracker, Larson, Cobalt, and many more — a testament to the brand's reputation for durability and consistent performance.</p><h3>A Complete Marine Windshield Wiper Ecosystem</h3><p>What sets AFI apart is the depth and cohesion of its wiper product ecosystem. Rather than offering isolated components, AFI designs its <strong>wiper motors</strong>, <strong>wiper arms</strong>, and <strong>wiper blades</strong> to work seamlessly together as integrated systems. This matters on the water, where mismatched components can lead to poor sweep coverage, premature wear, or outright failure in rough conditions.</p><p>AFI's wiper motors — from the compact, waterproof 1000 Series to the heavy-duty 2.5 Series — feature fully sealed, UV-stabilized housings, adjustable self-parking, and RF-shielded circuitry that keeps electrical interference at bay. The motors are available in both 12V and 24V configurations to match a wide range of vessel electrical systems.</p><p>Complementing the motors, AFI offers wiper arms and blades in both <strong>stainless steel</strong> and <strong>polymer</strong> construction. Stainless steel options deliver maximum corrosion resistance for offshore and saltwater use, while polymer alternatives offer a lightweight, rust-proof solution ideal for freshwater and light-duty marine applications. Blades feature marine-grade silicone squeegees designed to clear windshields cleanly and evenly, even at high sweep speeds.</p><h3>Wiper Kits for Easy Installation</h3><p>For boat owners looking for a straightforward upgrade or replacement, AFI's <strong>wiper kits</strong> bundle together a motor, arm, and blade in matched configurations. Kits like the AFI 500 Series include self-parking wipers that automatically return to the off position, stainless steel curved blades, and adjustable wiper arms — everything needed for a clean, complete installation without the guesswork of sourcing individual components.</p><h3>Engineered for the Marine Environment</h3><p>Every AFI product reflects an engineering philosophy centered on the unique demands of life at sea. Chrome-plated brass case construction, stainless steel shafts and front plates, and waterproof sealed motor housings are standard across the lineup. These aren't automotive wiper parts adapted for boats — they are marine-specific designs built from the ground up to resist corrosion, handle constant moisture exposure, and perform reliably season after season.</p><p>Whether you're replacing a worn-out OEM wiper motor or building a custom wiper system for a new build, <a href="/7226-afimarincoguestnicrobep">AFI/Marinco</a> offers the components and complete kits to get the job done right.</p>

Product Details

The AFI 2303A is a heavy-duty marine battery On/Off switch engineered for high-amperage applications in boats, RVs, and other marine electrical systems. This switch features alternator field disconnect (AFD) technology, allowing selection of any position including "Off" without damage to the alternator or electrical system. Built with a tough, glass-filled polycarbonate case, this switch is designed to withstand the harsh marine environment.

Key Features:

  • Continuous rating of 450 amps with intermittent capacity of 800 amps
  • Alternator field disconnect (AFD) protection prevents electrical system damage
  • 5/8" cable lug size for secure electrical connections
  • Compatible with 6, 12, 24, or 36 volt DC systems
  • Durable glass-filled polycarbonate construction
  • Simple On/Off operation for reliable battery control

Specifications:

  • Dimensions: 5-1/2" square x 3-1/2" deep
  • Gray color finish
  • Switch Type: Heavy-duty On/Off (single pole, single throw)
  • UPC: 046904230310

This heavy-duty switch is ideal for diesel-powered vessels, workboats, and any marine application requiring high-capacity battery isolation. The AFD feature makes it safe to switch between positions without disconnecting loads, protecting sensitive alternators and electronic equipment from voltage spikes.

USER FRIENDLY GREAT PRICE FAST SHIPPING HIGHLY RECOMMENDED PEOPLE TO DEAL WITH

Good

Excellent prices. Product was very good quality. I would recommend Autoplicity to others.

Found pics of louvers on a charger, thought it was pretty cool so I looked for some, found some, this site had lowest price so I bought me some.

Is to navigate. Found most of the parts I needed and GREAT prices.

Fantastic place to buy from. They had the best price for K&N oil filters for my motorbikes which was good enough. Then I ordered on a Saturday via normal shipping...got it Tuesday morning! Definitely going to order more in the future.

Great prices!!

Good products at a good price!<br>Never bought from them before, so I used Google Checkout, I always get nervous about buying from a new online store, but they came through just fine.<br>Shipping was a little expensive for the product I purchased and the shipping time, but was still cheaper than most anywhere else.<br>$12 to ship an automotive gauge [>2 lbs] and it was a 5 day ship.<br>Otherwise, a very good experience, B+ to A- just because of shipping cost/time.

So far so good

Everything was quick and easy. With discount for shipping, best price I could find on the internet. EDIT: Only problem I had was that the two day express shipping I had was a day late. I also never received a tracking number before I called CS. That was q

Quick and easy.
