Mercury – Next-Gen ERC Extension Harness Kit (Dual) | 5-Foot Extension | 98-8M0173753

Overview
This five-foot extension gives a dual-engine Next-Gen ERC setup the extra reach it sometimes needs when the stock harness won’t quite make the run. It’s useful on boats where the rigging path takes a sharper turn or the controls sit farther from the rig center than expected. Instead of forcing the wiring to stretch or snake through tight corners, this extension lets everything follow a smoother, cleaner route. It’s a small add-on that makes a busy dual-engine layout a lot easier to work with.

Key Features

• Dual-Engine ERC Use – Built for dual-engine Next-Gen electronic remote control systems.
• OEM Connectors – Factory ends that snap in firmly and stay put.
• Relaxed Wiring Path – Helps avoid tight bends or pulled wiring.
• Steady Control Signals – Maintains smooth throttle and shift communication.

Engine & Boat Compatibility
• Next-Gen ERC
• Dual engine

Performance & Practical Benefits
With a little more length to work with, the harness can follow a natural path instead of being forced into awkward turns. That usually means smoother control feel and fewer issues caused by stressed wiring. It also keeps the rigging bay from getting cramped, which makes service work a lot easier later. For dual-engine boats where space gets tight fast, this extension brings a bit of breathing room.

Why Buy OEM
OEM extensions stay reliable through vibration, heat, and saltwater, and the connectors fit exactly the way Mercury designed. You’re far less likely to run into odd glitches or loose connections than with aftermarket wiring. It’s dependable gear meant for long-term use.
