Quicksilver Aluminum Anode Kit for MerCruiser Bravo III Drives — 6-Piece Kit, OEM‑Spec Corrosion Protection

Quicksilver 888761Q04 is a complete aluminum anode kit made to protect MerCruiser Bravo III sterndrives from galvanic corrosion in freshwater and saltwater.

This replacement kit contains six aluminum anodes plus the hardware and instructions needed to inspect and fit them to Bravo III drives (serial numbers 0M179452 and up). Quicksilver manufactures these anodes to meet Mercury Marine OEM standards and mil-spec MIL-A-24779(SH), offering extended service life compared with standard zinc units. The kit is designed for easy removal and installation so routine maintenance is quick and reliable.

What parts are included and how do I install them?

The kit supplies six preformed aluminum anodes and the necessary fasteners so you can swap all worn sacrificial pieces in a single service session. Installation generally requires basic hand tools and follows the included instructions; most owners complete the job without specialized equipment.

• Six cast aluminum anodes sized for Bravo III sterndrives
• Complete attaching hardware set and mounting instructions
• Simple hand-tool installation—inspect, remove old anodes, fit new, torque fasteners to spec

Why choose aluminum anodes for my Bravo III instead of zinc?

Aluminum anodes perform better across both fresh and saltwater and typically last longer than zinc under the same conditions. Quicksilver’s aluminum alloy is produced to meet military and OEM standards, delivering dependable sacrificial protection while reducing the frequency of replacements.

• Effective in fresh and saltwater environments
• Meets or exceeds MIL-A-24779(SH) for extended life
• Reduces replacement intervals versus zinc alternatives

How often should I inspect or replace the anodes?

Regular inspection keeps galvanic corrosion from advancing to drive components. Check anode condition periodically—especially after a season of heavy use or extended dockside periods—and replace when you see significant pitting or loss of mass.

• Inspect visually at least once per season or after long storage
• Replace when anode shape is compromised or >50% consumed
• Follow mounting hardware torque and replacement guidance in the included instructions
