Mercury – Power Center Harness (4.0 m) | Rigging Accessory | 84-8M0210398

Overview
This 4-meter harness is for 20–35E electric rigs where the power center sits well away from the control post. It gives you plenty of room to run the cable cleanly through a longer rigging path without stretching a shorter harness or forcing awkward bends. The extra reach helps keep the wiring relaxed and makes the whole setup easier to service later.

Key Features
 • 4.0 m Length – Ideal for boats with a long helm-to-power-center run.
 • Control Post to Power Center Link – Transfers control and power signals between the two.
 • Sized for 20–35E Systems – Made specifically for these electric outboards.
 • Flexible Routing – Works well through rig tubes, bulkheads, and tight helm areas.
 • OEM SmartCraft Connectors – Proper fit, marine-grade wiring, and sealed ends.

Engine & Boat Compatibility
 • Mercury 20E / 35E electric outboards
 • Remote control post installations
 • Power center modules
 • Small and mid-size electric boats with long wiring runs

Performance & Practical Benefits
With the extra length, you can route the harness the way it should be routed—smooth, clean, and without forcing cable into sharp turns. A relaxed wiring run usually means better system reliability and fewer connectivity quirks. It also makes the space behind the helm a lot more manageable if you ever need to get back in there.

Why Buy OEM
OEM wiring fits right and holds up to vibration, moisture, and everyday use. You avoid the headaches that come from cheap aftermarket cables—loose pins, corrosion, and the odd electrical gremlins that always show up at the worst times.

FAQ
Q1: When should I step up to the 4.0 m harness?
A: When the 3.0 m cable still feels tight or your rigging path needs extra room to breathe.

Q2: Any setup needed afterward?
A: None—SmartCraft recognizes it automatically.

Q3: Safe for saltwater?
A: Yes. Just keep the connectors rinsed and clean during washdowns.

Q4: Anything to watch when routing it?
A: Avoid sharp edges and pinch points that could wear into the insulation.

Q5: What if the control post stops responding?
A: Check both ends first—a loose connector is usually the culprit.
