Mercury – JPI Side Power Thruster Adapter Harness | Rigging Accessory | 84-8M0125880

Overview
This adapter harness lets you run Side Power brand thrusters with Mercury’s Joystick Piloting for Inboards system. JPI already works with Vetus thrusters out of the box, but Side Power units need this harness to “speak the same language.” Each thruster gets its own adapter, keeping the wiring straightforward and the control signals clean. It’s a simple add-on that gives you more flexibility when choosing thruster equipment for an inboard setup.

Performance & Practical Benefits
With this harness in place, the JPI system can control Side Power thrusters the way it’s meant to—smooth pivots, gentle nudges, and predictable movement around docks. It eliminates the signal mismatch that would otherwise cause delays or odd responses. Everything feels more natural at the helm, especially during slow, careful maneuvers.

Why Buy OEM
OEM adapters plug in cleanly, hold up in the marine environment, and ensure the thruster and JPI system stay in sync. No guesswork, no sketchy connections, and no worrying about compatibility down the road.
