Marinco 14/3 Locking Extension Cord - 15A - 50'

The Marinco 14/3 Locking Extension Cord – 15A – 50' is purpose-built for serious boaters and anglers who demand reliable shore power connections in demanding marine environments. Whether you're running a livewell pump, battery charger, or galley appliances while docked, this marine-grade extension cord delivers the safety and durability that saltwater exposure and constant weather demand. At 50 feet, it reaches from most dock pedestals to your vessel without forcing you to choose between proximity and convenience.

Construction centers on marine-grade 14/3 SJTOW cable—a jacket formulation engineered to resist UV degradation, ozone, and salt spray that would compromise standard extension cords within a season. The universal slide-button locking mechanism on the female connector prevents accidental disconnection from vibration or movement, a critical safety feature when equipment depends on continuous power. A lighted female end provides immediate visual confirmation of power delivery, allowing you to troubleshoot connection issues without a multimeter and reducing the risk of operating equipment on dead circuits.

This cord is essential for boats with onboard electronics, refrigeration, or charging systems that require stable AC power while moored or at a marina slip. The 15-ampere rating suits typical marina pedestals and suits powering multiple accessories simultaneously without exceeding safe circuit capacity. For anglers and cruisers who live aboard seasonally or maintain equipment in salt-air environments, marine-grade cable pays dividends in reliability—standard contractor-grade cords degrade within months when exposed to marine conditions.
