Performance & Practical Benefits
A clean harness run makes the helm feel steadier because the system isn’t juggling extra connections. You also save time during installs and later service since everything follows one clear route. Shifting and throttle inputs feel more natural when the communication path is simple and not stretched or crowded. It just keeps the whole setup calmer.

Why Buy OEM
OEM harnesses hold tight through vibration, heat, and saltwater spray. The connectors fit exactly the way Mercury intended, which helps avoid the weird glitches you sometimes get with off-brand wiring. It’s gear you can set and forget.
