Mercury – Boat Harness Adapter | 6-Pin Female-to-Female, 6-Foot | 84-883459T01

Overview

When repowering or updating rigging, it’s common to end up with a new engine that uses a female 6-pin connector while the boat still has a female 6-pin harness. The Mercury 84-883459T01 Boat Harness Adapter fixes that mismatch. With female connectors on both ends and six feet of length, it gives you the reach and the correct gender pairing needed to connect the engine and boat harness without cutting, splicing, or reworking the wiring.

Key Features

• 6-Pin Female-to-Female Adapter – Connects a female engine connector to a female 6-pin boat harness.
• Six-Foot Length – Adds extra reach for cleaner routing, especially in tight rigging spaces.
• Direct Plug-In Fit – Creates the proper connection without modifying the harness.
• OEM Connector Build – Factory-fit ends stay tight and hold up to vibration.
• Neat Rigging Solution – Helps organize the harness run during repowers or upgrades.
• Reliable Signal Path – Maintains clean communication between the engine and helm systems.

Compatibility

• Mercury engines equipped with a female 6-pin connector
• Boats using a female 6-pin boat harness
• Standard 6-pin analog/SmartCraft hybrid rigging paths

Performance & Practical Benefits

This adapter removes an annoying but common rigging obstacle—two female connectors that can’t meet without an intermediary. The six-foot length gives you enough room to route the harness naturally instead of forcing tight bends or stretching the cable. Once it’s plugged in, the connection feels solid, communication stays clean, and the overall rig looks much better organized.

Why Buy OEM

Harness adapters need solid sealing, proper pin alignment, and tight connector tension to work well over time. Mercury’s OEM design ensures the connection won’t wiggle loose, corrode, or cause intermittent faults—problems that often pop up with off-brand adapters. The factory build keeps the engine and boat harness communicating reliably season after season.
