Marinco

<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 174ARV is a heavy-duty generator power adapter designed to safely provide 30 amp service to your RV from a 50 amp generator power outlet. This pigtail-style adapter features Marinco's reliable locking design to ensure a secure connection during operation.

Key Features:

  • Converts 50 amp 4-prong generator outlet to 30 amp RV service
  • Locking connector design prevents accidental disconnection
  • Polarized specifically for RV applications
  • Integrated handle for easy plug and unplug operation
  • Durable weather-resistant construction for outdoor use
  • Pigtail configuration provides flexible connection

This adapter is essential for RV owners who need to connect their 30 amp RV electrical system to a 50 amp generator outlet, allowing you to utilize available generator power while maintaining proper amperage for your coach. The locking mechanism and robust construction ensure reliable power delivery in campground and off-grid applications.

It should be clearly noted that the Battery acid to activate this was not included. We had to purchase this elsewhere and the only size they had avail was a large package for an additional 20.00 of course we only needed about 8 to 10 oz. So now the rest of this will sit on a shelf forever... Otherwise the shipping time and product was fine.

great experience

great prices, great products

Thanks for the great service

I am actually looking for a 3.55 gear set for the '89 Toyota Land Cruiser, but I have had no luck in finding that ratio. If the 3.55 is available, please change to the 3.55 ratio.

excellent company

Had what I needed for the cheapest price. Thanks.
