The Marinco 6373EL-B is engineered to excel in harsh marine conditions. Its solid cast 316 stainless steel construction offers superior corrosion resistance, ensuring longevity even when exposed to saltwater and humidity. The inlet’s nickel-plated brass blades further enhance durability by preventing corrosion, maintaining reliable electrical conductivity over time.
Easy Lock™ System: A Game-Changer
Marinco’s proprietary Easy Lock™ System simplifies shore power connections.

The locking ring features 180° lock locators for improved grip, ensuring a watertight seal that protects against water ingress. This system is compatible with both Easy Lock™ and threaded cordsets, offering versatility for boaters.
Robust Rear Enclosure
The rear enclosure, made from flame-resistant UL94V0 plastic and glass-filled polyester, adds strength and flexibility. It includes integral strain relief that complies with ABYC standards, reducing wear on cables and ensuring secure connections. The enclosure’s multi-position design allows for flexible installation, accommodating various boat configurations.
Easy Installation: Hassle-Free Setup for All Boaters
Installing a shore power inlet can be daunting, but the Marinco 6373EL-B makes it accessible for both professionals and DIY enthusiasts. The inlet comes with a solid neoprene mounting gasket to ensure a watertight seal against the hull. While #8 mounting screws are not included, the installation process is straightforward, with clear instructions provided in the manual.
Step-by-Step Installation Guide
- Select Location: Choose a dry, accessible spot on the boat’s exterior, away from heavy water exposure.
- Cut Opening: Use the provided template to cut a precise hole for the inlet.
- Mount Gasket: Place the neoprene gasket between the inlet and hull to prevent leaks.
- Secure Inlet: Fasten the inlet using #8 flat or oval head screws.
- Connect Wiring: Attach up to 6 AWG wire to the Perma-Lock™ terminals, ensuring proper polarity.
- Attach Rear Enclosure: Secure the glass-filled polyester enclosure for added protection.
The Soft Touch cap enhances usability by staying open during cord connection, allowing one-handed operation. A slight press closes it securely, maintaining the watertight seal.
Safety First: Protecting Your Vessel and Crew
Safety is paramount on the water, and the Marinco 6373EL-B is designed with multiple protective features. Its watertight Easy Lock™ system prevents electrical shorts caused by water ingress. The robust stainless steel and flame-resistant plastic materials reduce the risk of fire or electrical faults. Additionally, the inlet complies with stringent standards, including:
- UL Marine Listed (File E57672): Ensures compliance with marine electrical safety requirements.
- CSA Certified (File LR81290): Validates quality and safety for North American markets.
- ABYC and U.S. Coast Guard Standards: Guarantees compatibility with marine regulations.
The Perma-Lock™ terminals securely grip wires up to 6 AWG, minimizing the risk of loose connections that could lead to arcing or overheating. However, users should note the California Proposition 65 warning regarding di(2-ethylhexyl)phthalate (DEHP), a chemical in some components that may pose health risks. Boaters should handle the product with care and follow safety guidelines.
