Sierra WH10520-1 Male Boat Side Trolling Motor Plug, 12 Volt, 6 Inch 8 Gauge Wire with Butt Connectors

The Sierra WH10520-1 is a male boat side trolling motor plug rated for 12 volt systems. It comes pre-wired with 6 inch, 8 gauge wire leads terminated in butt connectors, so it splices directly into the boat's existing trolling motor wiring without additional crimping hardware for the connector end. The plug is the boat side half of a two-piece connection system and is designed to mate with the Sierra WH10530-1 female motor side trolling motor socket, which is sold separately. This setup lets a trolling motor be quickly disconnected from the boat's power wiring for storage, motor swaps, or seasonal removal, rather than requiring the wiring to be hardwired or spliced every time the motor is mounted or removed. Each unit is sold individually (one plug per pack), making it a straightforward replacement or add-on part for boaters upgrading or repairing their trolling motor quick-connect wiring. Because it is a 12 volt plug with 8 gauge wire, it is sized for typical trolling motor current draw rather than higher-voltage 24V or 36V systems. The heavier 8 gauge wire gauge helps minimize voltage drop over the connection compared to thinner wire options.
