3. Attwood 12001-7 Trolling Motor Plug and Socket: Solid Performance for Value
Based on the spec sheets and owner feedback, a key limitation of the Attwood 12001-7 is its design primarily for 12V, 2 pin systems. While perfectly adequate for many smaller trolling motors, it lacks the capacity and pin configuration required for higher voltage (24V or 36V) or higher amperage trolling motors that are common on larger boats. Pushing this plug beyond its intended electrical limits could lead to overheating or premature failure.
Boaters with powerful 24V or 36V trolling motors, or those planning to upgrade to such systems in the future, should definitely skip this plug. It is best suited for straightforward 12V applications where its specified electrical ratings align with the motor’s requirements, offering reliable performance within those parameters.
- Durable brass electrical contacts for reliable current flow
- Weather resistant construction suitable for marine use
- Twist lock design helps prevent accidental disconnection
Pros: Reliable connection for standard 12V trolling motors; Good balance of durability and affordability; Easy to install with common tools

Frequently Asked Questions
What is a trolling motor plug?
A trolling motor plug is a specialized electrical connector designed to provide a secure and reliable power connection between your boat’s battery system and your trolling motor. It typically consists of a male plug that attaches to the motor’s wiring and a female receptacle that mounts to the boat, allowing for easy disconnection and protection of the electrical contacts.
Why do I need a special plug for a trolling motor?
Trolling motors draw significant current, often ranging from 30 to 60 amps or more. Standard household plugs are not designed for such high amperage or for the harsh marine environment. A dedicated trolling motor plug ensures a safe, corrosion resistant, and vibration proof connection, preventing overheating, power loss, and potential electrical hazards that could arise from an inadequate connector.
Are all trolling motor plugs universal?
No, trolling motor plugs are not universally compatible. They vary in pin configuration (e.g., 2 pin for 12V, 3 pin for 24V, 4 pin for 36V systems), amperage ratings, and physical design. It is crucial to select a plug that matches your trolling motor’s voltage and current requirements, as well as the mounting space available on your boat. Some plugs are also brand specific.
How do I install a trolling motor plug?
Installation typically involves cutting your trolling motor’s power cables to length, stripping the wire ends, and securely connecting them to the plug’s terminals, often using screw terminals or crimp connectors. The receptacle then requires drilling a mounting hole in your boat’s deck or transom and securing it with fasteners. Always follow the manufacturer’s instructions and ensure correct polarity to prevent damage to your motor or electrical system. It is advisable to disconnect all power sources before beginning installation.
What's the difference between 2-pin and 3-pin plugs?
The main difference lies in their voltage compatibility. A 2 pin plug is typically used for 12 volt trolling motor systems, providing a positive and a negative connection. A 3 pin plug is commonly used for 24 volt systems, allowing for two 12 volt batteries to be wired in series, often with a common ground or a separate ground for charging, while a 4 pin plug is for 36 volt systems. Always match the plug’s pin configuration to your trolling motor’s voltage setup.
