Quicksilver 8M0085692 Mercathode Electrode Assembly Kit for MerCruiser Sterndrives

The Quicksilver 8M0085692 Mercathode Electrode Assembly is an OEM replacement component for Mercury Marine's Mercathode corrosion protection system. The Mercathode system works by passing a low-level electrical current through a submerged electrode to counteract galvanic corrosion on MerCruiser sterndrives and outdrives — a critical defense for boats moored in saltwater, brackish, or marina environments where stray electrical currents accelerate metal deterioration.

Key Features:

• OEM Quicksilver part — direct factory replacement for Mercury Marine Mercathode systems
• Designed for use with MerCruiser Alpha and Bravo series sterndrives
• Includes quick-connect wiring connector for straightforward installation
• Supersedes earlier part numbers including 98869A17, 98869A11, 98869A4, and 98869A16
• Backed by Mercury Marine's 1-year factory warranty against defects in materials and workmanship

The Mercathode electrode assembly is the active element of the Mercathode system, mounted at the gimbal housing and submerged in water during operation. Over time, electrodes wear and must be replaced to maintain effective cathodic protection. Using a genuine Quicksilver replacement ensures proper system function and continued protection of expensive drive components.
