Marinco

<h3>About Marinco: Trusted Marine Electrical Innovation Since 1972</h3><p><strong>Marinco</strong> has been a cornerstone of the marine electrical industry for more than five decades. The brand traces its roots to 1972, when founder Bud Toly, frustrated by the poor quality of available marine electrical gear, set out to engineer something better from the ground up. That spirit of problem-solving and uncompromising quality has defined Marinco ever since. Today, the brand is part of the Navico Group — a global leader in marine technology — and continues to serve everyone from weekend bass anglers to commercial vessel operators and major OEM boatbuilders.</p><p><a href="/11273-marinco">Marinco</a> is best known as a world-class manufacturer of shore power systems, but its catalog spans far beyond that single category. The brand's engineers design products for the real-world punishment of salt, spray, and constant moisture — environments where inferior components fail quickly and safe, reliable electrical connections are non-negotiable. Industry involvement is baked into the brand's DNA: <a href="/11273-marinco">Marinco</a> actively participates on ABYC standards committees, helping shape the very regulations its products are built to exceed.</p><h3>Shore Power, Signaling, and Ventilation — Built for the Water</h3><p>At the core of Marinco's reputation is its shore power lineup: heavy-duty cordsets, inlets, outlets, and adapters engineered for both 30-amp and 50-amp applications. The patented EEL (Easily Engaged Lock) jaw-clamp system allows one-handed connection without the frustration of threaded locking rings, and many premium connectors feature built-in LED power indicators so boaters can confirm live power at a glance. Products are engineered to CSA and UL standards, and nickel-plated brass contacts are used throughout to resist the corrosion that plagues lesser marine connectors.</p><p>Beyond shore power, Marinco offers an impressive range of marine accessories that keep vessels safe and comfortable. The brand's <a href="/11273-marinco-air-horns-201608">air horns</a> are a staple on boats of all sizes, delivering the kind of authoritative, regulation-compliant signals that can genuinely protect lives on the water. And for boaters who want to keep cabin air fresh without running down their battery bank, Marinco's <a href="/11273-marinco-solar-cabin-vents-202545">solar cabin vents</a> from its trusted Nicro line provide around-the-clock ventilation powered entirely by the sun — and a built-in rechargeable battery when the sun goes down.</p><h3>Why Boaters Choose Marinco</h3><ul><li><strong>OEM Trust:</strong> Major boatbuilders specify Marinco electrical components from the factory, a testament to the brand's reliability standards.</li><li><strong>Standards Leadership:</strong> Active participation on ABYC committees means Marinco products don't just meet standards — they help write them.</li><li><strong>Marine-Grade Engineering:</strong> Every product is designed for salt air, vibration, and moisture, not just adapted from a land-based design.</li><li><strong>Complete System Thinking:</strong> With over 800 electrical products engineered to work together, Marinco makes it easy to build a cohesive, safe onboard electrical system.</li><li><strong>Decades of Refinement:</strong> Over 50 years of feedback from real boaters has shaped every product iteration, from connector geometry to diaphragm materials.</li></ul><p>Whether you're outfitting a new build, upgrading aging shore power hardware, adding a safety horn, or solving a below-decks ventilation problem, Marinco brings proven engineering and category-defining products to every corner of the job.</p>

There was rust on one of the mufflers and they took longer than the catalytic converters to arrive. At the exhaust shop, I was only allowed to install one set because of some law that prohibits moving to dual exhaust. I've got to look into this law and find another exhaust shop to install the second set

Great price and fast service
