Mercury – Global Wake Harness | 40-Foot Harness | 84-8M0163386

Overview
This 40-foot Global Wake harness is for boats where the wake module sits a long way from the rig center and the shorter harnesses just don’t cut it. Wide transoms, long rigging channels, and a few tight corners can make the standard length feel stretched fast. This harness gives you the breathing room to route the cable the way it wants to run—no forcing bends, no pulling it tight. It keeps the wake wiring calmer and a lot easier to deal with when you’re working behind the scenes.

Performance & Practical Benefits
With extra length, the harness can follow a more relaxed path through the boat. You’ll usually notice smoother wake-control response because the wiring isn’t kinked or squeezed. It also gives you more room to work in the rigging bay—something you’ll appreciate the next time you’re tracing wires or checking connections. On bigger hulls, this extra space simply makes everything feel more manageable.

Why Buy OEM
OEM harnesses stay tight under vibration, heat, and saltwater exposure, and the connectors fit exactly how Mercury designed them. You avoid the random glitches and loose plugs that show up with off-brand wiring. It’s dependable gear you can set and forget.
