Marinco 70A Trolling Motor Receptacle

The Marinco 70A Trolling Motor Receptacle (model 12VBRS3) is a sealed, waterproof connector designed to handle the high amperage demands of modern trolling motors. With a continuous 70-amp rating, this receptacle accepts wire gauges up to 6AWG, making it suitable for serious freshwater and saltwater fishing applications where reliable, high-current connections are essential.

Built for durability in harsh marine environments, the 70A receptacle features integrated strain relief to protect against mechanical stress and wire fatigue. The keyed design with thumbprint locator ensures proper orientation during connection, eliminating guesswork and reducing the risk of reverse-polarity installation. The sealed, waterproof construction prevents corrosion and salt spray intrusion—critical for anglers operating in saltwater conditions where standard connectors fail prematurely. The receptacle accepts industry-standard 6AWG marine-grade wire, allowing anglers to build or upgrade their own trolling motor harnesses without compromising safety or performance.

This receptacle is engineered for anglers upgrading to higher-amperage trolling motors or replacing corroded connectors on existing systems. Whether you're rigging a new bow-mounted motor for a tournament bass boat or retrofitting a saltwater skiff, the 70A Marinco receptacle provides the current capacity and environmental sealing required for reliable, long-term performance. It's an OEM-quality upgrade from a trusted marine electrical brand, backed by specifications that meet modern trolling motor demands.
