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 121A marine power adapter pigtail provides a reliable connection between 50-amp dock power and 30-amp boat systems. This essential adapter features a dock-side male 50A 125/250V locking plug that converts to a boat-side female 30A 125V locking connector, allowing boats with 30-amp shore power inlets to safely utilize 50-amp dock pedestals.

Key Features:

  • Dock side: Male 50A 125/250V locking plug (NEMA SS2-50P)
  • Boat side: Female 30A 125V locking connector (NEMA L5-30R)
  • Unique sealing collar system creates positive mechanical connection between adapter and cordset
  • Maximum moisture protection for wet marine environments
  • Protective covers included for both ends when not in use
  • Rated for wet locations and harsh marine conditions
  • Marinco quality construction for reliability and durability

This pigtail adapter is ideal for cruisers and boaters who frequently encounter marinas with 50-amp service but have 30-amp onboard systems. The sealing collar system ensures a weatherproof connection that stands up to the demanding marine environment, while the included covers protect connections from corrosion when stored.

1st purchase, but went well. Very quick shipping!

Needed some specialty parts to finish up a project, check Summit and it was going to be mid-month before the parts would be in stock...Autoplicity had them in stock and at a MUCH better price. First time customer soon to be a lifelong repeat customer!

Easy to use

this was a quick and easy order, although they came up in free shipping, i was charged for shipping. BUT, they were the least expensive for what i ordered on the entire web. thanks for being the lowest price!!!

Don't know yet. You haven't a chance to mess any thing up yet.
