Overview

The MotorGuide 8M4000953 is a 2-prong trolling motor power plug rated for 50 amps for 12V, 24V, or 36V power systems.

It creates a clean disconnect point between your trolling motor and the boat’s power circuit, which is handy when you remove the motor for trailering, store the boat, or need to service wiring at the bow. If your current plug feels loose, shows heat marks, or cuts out when the boat bumps, replacing the connector is a smart place to start.

Key features

• 2-prong trolling motor power plug format
• 50 A rating for high-current trolling motor circuits
• Works with 12V, 24V, and 36V trolling motor power setups
• Built to seat firmly in a matching receptacle for a steady connection
• Makes it easier to disconnect power at the bow for storage, trailering, or maintenance

Compatibility and fit

This plug is intended to mate with a matching 2-prong, 50 A trolling motor receptacle. Before ordering, compare the prong layout and housing style to what’s installed on your boat, since 2-prong plugs are not all interchangeable across brands and patterns.

Voltage is not usually the limiting factor here since the plug supports 12V through 36V. The important checks are connector style and that your circuit protection and wiring are appropriate for a 50 A connector and your trolling motor’s current draw.

Installation and setup

Disconnect the batteries before any wiring work. Make electrical connections with marine-appropriate crimping and sealing so water and corrosion do not creep into the joint over time. Add strain relief and route the cable so the plug is not taking the load when the motor turns, stows, or gets bumped.

On open decks, place the connection point where it will not sit in standing water and where it is less likely to take direct washdowns. Keeping the contacts clean and the fit tight helps prevent heat build-up on high-current trolling motor runs.

Use on board

This style of plug is commonly used on bow-mount trolling motor installs where you want a quick disconnect close to the motor bracket. It also fits small-boat and removable-motor setups where you regularly pull the motor between trips, as long as the mating receptacle matches the same 2-prong 50 A pattern.
