<h3>About Marinco</h3><p>Marinco has built a decades-long reputation as one of the most trusted names in marine electrical systems. As part of the <strong>Navico Group</strong> — a global leader in marine, RV, and specialty vehicle technology — Marinco focuses exclusively on the electrical needs of recreational and commercial boaters, delivering products that combine reliability, safety, and ease of installation.</p><p>Boaters depend on their onboard electrical systems in ways that land-vehicle drivers rarely have to think about: shore power connections, battery management, wiper systems that work in salt air and spray, and safety signaling equipment. Marinco has engineered solutions for every one of these demands, earning its place as a go-to brand at marinas and on vessels ranging from modest day cruisers to serious offshore fishing boats.</p><h3>Shore Power &amp; Charging Systems</h3><p>One of Marinco&apos;s most recognized product areas is its shore power ecosystem. The brand&apos;s <a href="/11273-marinco-shorepower-accessories-200944">Shorepower Accessories</a> — including inlets, connectors, cords, and power management products — are designed to meet rigorous marine electrical standards, helping boaters safely draw power from marina pedestals. These products are engineered to resist the corrosion and moisture exposure that define the marine environment.</p><p>Complementing the shore power lineup, Marinco&apos;s <a href="/11273-marinco-battery-chargers-200141">Battery Chargers</a> are built specifically for the demands of marine use. Whether maintaining batteries during off-season storage or keeping house and starting batteries topped off at the dock, Marinco chargers provide reliable multi-bank charging with the safety features boaters require.</p><h3>Windshield Wiper Systems</h3><p>Visibility on the water can be a matter of safety, and Marinco takes it seriously with a full range of wiper products. The brand&apos;s <a href="/11273-marinco-windshield-wiper-motor-8824">Windshield Wiper Motors</a> are purpose-built for marine applications, engineered to withstand constant exposure to salt spray, humidity, and the vibration of an active vessel. Marinco also offers a comprehensive selection of <a href="/201195-windshield-washers-wipers-replacement-motors-marinco-11273">Windshield Washers, Wipers &amp; Replacement Motors</a> so boaters can maintain or upgrade existing systems without replacing the entire assembly — a practical and cost-effective approach for vessel owners.</p><h3>Marine Horns</h3><p>Safety signaling is a legal requirement on the water, and Marinco&apos;s <a href="/11273-marinco-horn-10051">Horns</a> deliver the sound output needed to meet U.S. Coast Guard requirements. Built for the marine environment, these horns resist corrosion and are designed for straightforward installation on a wide variety of vessel types.</p><h3>Why Choose Marinco?</h3><ul style="list-style:disc"><li><strong>Marine-specific engineering:</strong> Every product is designed and tested for the unique challenges of the marine environment — moisture, salt, vibration, and UV exposure.</li><li><strong>Industry standards compliance:</strong> Marinco products are built to meet relevant marine electrical standards, giving boaters peace of mind at the dock and underway.</li><li><strong>Broad compatibility:</strong> With a catalog of over 300 products, Marinco supports a wide range of vessel types and electrical configurations.</li><li><strong>Trusted by professionals:</strong> Marinco products are widely specified by marine technicians and OEM boat builders, a testament to their quality and dependability.</li></ul>

Product Details

The Marinco 152AY is a heavy-duty shore power Y-adapter that allows two boats with 30-amp service to share a single 50-amp dock receptacle. This adapter features a 50-amp 125V locking male plug on the dock side that splits into two 30-amp 125V locking female connectors on the boat side, enabling dual 30-amp connections from one 50-amp power source.

Key Features:

  • Dock side: 50A 125V male locking plug (NEMA SS2-50P)
  • Boat side: Two 30A 125V female locking connectors (NEMA L5-30R)
  • Patented sealing collar system provides superior weatherproof protection
  • Heavy-duty marine-grade construction resists corrosion in saltwater environments
  • Heat-resistant thermoplastic housing withstands extreme temperatures
  • Nickel-plated brass contacts ensure reliable conductivity
  • Fully molded design eliminates potential failure points

This Y-adapter is ideal for marinas accommodating multiple vessels with 30-amp service, or for larger boats with dual 30-amp inlets that need to connect to 50-amp shore power. The sealing collar system keeps moisture out of connections, preventing corrosion and ensuring safe, reliable power transfer. Marinco's industry-leading design meets all applicable UL and marine safety standards.
