Mercury Marine SmartCraft Outboard Analog Gauge Interface Kits & Harnesses

Mercury Marine SmartCraft Outboard Analog Gauge Interface Kits & Harnesses help bridge the gap between modern engine data and the analog gauges many boaters still prefer at the helm. These OEM components support clean, dependable rigging connections so your gauges and engine systems communicate properly. Just as important, Mercury’s strong warranty coverage on many engines also extends to the controls and key SmartCraft rigging components installed on your boat.


Why Rigging Matters

Installing an outboard—often called rigging—involves much more than bolting the engine to the transom. A proper rigging job includes connecting and routing the systems that make the boat run safely and comfortably, such as:

  • Steering systems
  • Throttle and shift controls
  • Engine control and monitoring systems
  • Navigation and communication equipment
  • Helm gauges and indicators

When rigging is done right, you get smoother operation, fewer electrical headaches, and more confidence in the information you see at the dash.


What These Interface Kits and Harnesses Do

SmartCraft analog gauge interface kits and harnesses are designed to support reliable signal routing and system compatibility for SmartCraft-equipped outboards. Depending on your setup, these components can help you:

  • Connect analog gauges to SmartCraft-capable engine data
  • Complete a clean helm install with correct-length harnessing and proper connectors
  • Reduce wiring issues by using OEM-fit components built for the marine environment
  • Upgrade or replace worn rigging parts as part of your maintenance plan

Make Rigging Part of Your Maintenance Plan

Outboard rigging lives in a harsh environment—heat, vibration, moisture, and salt air all take a toll over time. Inspecting harnesses and connections is an essential part of routine maintenance, especially if you notice intermittent gauge readings, corrosion at connectors, or changes in electrical performance. Replacing worn harnesses with OEM Mercury components helps keep your system reliable and your dash data accurate.
