Product Details

The Quicksilver 888755Q04 is a complete magnesium sacrificial anode kit engineered to protect MerCruiser MR and Alpha One sterndrive units from galvanic corrosion in freshwater environments. Designed specifically for drives with serial numbers 6225577 through 0D469828 (1984–1991), this kit is a direct OEM replacement produced to Mercury Marine's original equipment specifications.

Magnesium is the preferred anode material for freshwater use, offering superior electrochemical activity compared to aluminum or zinc anodes in low-conductivity water. By acting as a sacrificial metal, the anodes attract corrosive galvanic activity away from your drive's critical metal components, extending the life of your outdrive investment.

Kit Includes:

  • Trim tab anode
  • Gimbal nut anodes
  • Driveshaft plate anode
  • Complete attaching hardware for fast, easy installation

Key Features:

  • Freshwater use only — magnesium formulation optimized for low-salinity environments
  • Mil-Spec A-21412(SH) compliant — cast magnesium meets or exceeds military specification standards
  • OEM fit and finish — manufactured to Mercury Marine original equipment specifications
  • Easy inspection and replacement — straightforward design allows for quick periodic checks and swap-outs
  • Complete kit — all attaching hardware included, no separate hardware purchase needed

Quicksilver is the factory-authorized supplier of Mercury Marine replacement parts, backed by over 65 years of marine industry expertise. Cross-reference part numbers for this kit include Sierra 18-6150, Martyr CMALPHAGEN1KITM, Seachoice 95011, and Tecnoseal 20800MG. Inspect anodes periodically — a corroded or painted-over anode will not provide effective protection.
