Mercury – Thruster Power to Battery Cable (20 ft) | Rigging Accessory | 84-8M0174061

Overview
This 20-foot power cable gives your thruster a solid, direct feed from the battery. It’s meant for boats where the battery sits a good distance from the thruster module, or when the wiring path takes a longer route than usual. The extra length helps you route the cable cleanly without stretching or forcing tight bends. Once it’s hooked up, the thruster usually reacts with steadier, stronger push, especially during docking or windy maneuvers.

Key Features
 • 20-Foot Positive Cable – Made for longer battery-to-thruster runs.
 • Red Power Lead – Sends clean, consistent voltage to the thruster.
 • Stable Power Delivery – Helps the thruster respond smoothly without drop-off.
 • Marine-Grade Build – Insulation built for heat, spray, and vibration.
 • OEM Fit – Matches Mercury’s connectors and wiring standards.

Engine & Boat Compatibility
 • Bow and stern thrusters
 • Joystick Piloting for Outboards
 • Single-engine pontoon JPO setups
 • 12V and 24V thruster systems

Performance & Practical Benefits
A proper-length power cable goes a long way toward smoother thruster performance. When the cable isn’t stretched or routed awkwardly, voltage stays steady, and the thruster gives more predictable push when you need it. It’s especially noticeable in tight marinas or when holding position in a crosswind.

Why Buy OEM
OEM cables are built with the right gauge, proper insulation, and connectors that hold up in real marine conditions. They resist corrosion and help avoid the odd low-voltage issues that show up with cheaper aftermarket wiring.

FAQ
Q1: When should I choose the 20-foot cable?
A: When the thruster and battery are far apart or the route to the module isn’t simple.

Q2: Can I shorten or splice it?
A: Not recommended—splicing can cause voltage loss and heat issues.

Q3: Is it okay for saltwater use?
A: Yes, just keep the terminals clean during your washdowns.

Q4: Anything to check before routing it?
A: Make sure the cable won’t rub on sharp edges or get pinched.

Q5: What if the thruster still feels weak?
A: Check your battery, grounds, and connections—power issues usually start there.
