Mercury – Next-Gen ERC Extension Harness Kit (Single) | 5-Foot Extension | 98-8M0173751

Overview
This five-foot extension gives a single-engine Next-Gen ERC setup a little extra reach when the stock harness comes up short. It’s handy on boats where the rigging path takes a sharp turn or the control station sits farther from the rig center than expected. Instead of forcing the wiring to stretch or bend too tight, this piece lets everything run in a calmer, cleaner line. It’s a simple fix that makes the whole control run easier to deal with.

Performance & Practical Benefits
A little extra slack goes a long way—controls usually feel smoother when the harness isn’t kinked or stressed. The wiring lays out more naturally, which makes tracing it later a lot easier. In tight rigging bays, it keeps things from feeling jammed or overcrowded. It’s the kind of small upgrade that makes daily use and future service a lot less frustrating.

Why Buy OEM
OEM wiring holds up to vibration, heat, and saltwater better than off-brand extensions. The connectors match Mercury’s design, so you don’t get loose fits or odd glitches. It’s dependable hardware built to last.
