A Universal Trolling Motor Connection Built for Multi-Voltage Systems
The Sierra WH10620 is a heavy-duty trolling motor plug and receptacle set designed for 2 or 3-wire configurations across 12V, 24V, 12/24V, 24/36V, and 36V DC systems. With a watertight seal, corrosion-resistant plated-brass contacts, and a standard 1-1/8" mounting hole, it installs cleanly in most boat consoles and gunwale panels — and is rated for up to 62A at 36VDC when paired with the matching Sierra WH10620P plug.

Parts Desk Insights
The WH10620 is the best choice for boaters who want a single receptacle that works across multiple voltage configurations — particularly useful if you run different trolling motors on the same boat or plan to upgrade from a 12V to a 24V or 36V system in the future. The 62A rating at 36VDC covers the draw of most high-thrust trolling motors on the market. If you need the matching male plug, see the Sierra 12V 2-Wire Plug (WH105201) for 12V systems or the Sierra 24V 3-Wire Plug (WH105401) for 24V systems.
