Mercury SmartCraft Power Harness Kit – 30ft

The Mercury Marine 899785K30 SmartCraft Power Harness Kit is a genuine Mercury OEM electrical harness designed to provide switched accessory power and SmartCraft network power distribution for Mercury SmartCraft-equipped vessels. Measuring 30 feet (9.1 metres) in length, this harness is commonly used when connecting SmartCraft systems, gauges, VesselView displays and accessory circuits to a vessel’s electrical system.

The harness kit is designed to provide clean, reliable power to SmartCraft components while maintaining proper communication throughout the SmartCraft network. It is commonly installed during new vessel rigging, repowers and SmartCraft upgrades where a longer power harness run is required.

Manufactured to Mercury Marine specifications, the harness features marine-grade wiring, sealed connectors and durable insulation designed to withstand moisture, vibration, heat and corrosion in harsh marine environments. Genuine Mercury harnesses ensure reliable system operation and compatibility with Mercury SmartCraft instrumentation and electronics.

This harness kit supersedes Mercury part number 889611K01, making it the current OEM replacement for many earlier SmartCraft power harness installations.
