Mercury – Tiller Power Harness (4.0 m) | Rigging Accessory | 84-8M0210367

Overview
This 4-meter tiller harness is made for 20–35E electric outboards when the power center sits well away from the tiller cowl. It gives you the extra reach you need to run the wiring cleanly through longer rigging paths without stretching a shorter cable or forcing sharp bends. With the added length, the install feels a lot more relaxed and the wiring stays neat and easy to work around.

Key Features
 • 4.0 m Length – Plenty of distance for long or wide tiller layouts.
 • Tiller Cowl ↔ Power Center Link – Carries both power and control signals.
 • Made for 20–35E Models – Correct pinout and sizing for these electric rigs.
 • Flexible Jacket – Routes easily through rig tubes and tight console spaces.
 • OEM SmartCraft Connectors – Marine-rated, solid-fit plugs.

Engine & Boat Compatibility
 • Mercury 20E / 35E electric outboards
 • Tiller-handle setups
 • Power center modules
 • Small and mid-size electric boats with longer wiring runs

Performance & Practical Benefits
A longer harness lets you route the cable the way it wants to go—smooth and natural, without sharp corners or tension. That helps reduce wear, keeps the connection steady, and avoids the little electrical hiccups that pop up when wiring is under strain. It also frees up space under the cowl, making future service a lot easier.

Why Buy OEM
OEM wiring fits right, lasts longer, and handles vibration, spray, and daily use far better than cheap aftermarket cables. You avoid loose pins, corrosion issues, and the random glitches that show up when wiring doesn’t match Mercury’s spec.

FAQ
Q1: When should I use the 4.0 m harness?
A: When even the 3.0 m version feels tight or your wiring path is unusually long.

Q2: Does anything need to be set up afterward?
A: Nope—SmartCraft recognizes it automatically.

Q3: Is it fine for saltwater rigs?
A: Yes. Just rinse the connectors during your normal washdown.

Q4: Anything to avoid when routing it?
A: Steer clear of sharp edges or pinch points that could rub through the jacket.

Q5: What if the tiller stops responding after install?
A: Check both connector ends first—loose plugs are almost always the cause.
