Freshwater-Optimized Corrosion Protection for Bravo 2 & 3 Sterndrives
Protect your MerCruiser Bravo 2 or Bravo 3 sterndrive from galvanic corrosion with this complete aluminum anode kit (B23KA). Aluminum anodes are the preferred choice for freshwater and mixed-use environments, offering superior electrochemical activity compared to zinc in low-salinity water — meaning better protection where zinc anodes can passivate and fail.
This kit covers all the critical corrosion points on Bravo 2 and Bravo 3 drives, giving you everything needed for a full anode replacement in one purchase.

Parts Desk Insights
Aluminum anodes are the best choice for freshwater lakes, rivers, and mixed-use boating where the boat moves between fresh and salt water. In fresh water, zinc anodes can develop a passive oxide layer that stops them from working — aluminum stays active and keeps protecting your drive. For boats that operate exclusively in saltwater or brackish water, zinc is the correct choice instead: MerCruiser Bravo 2 & 3 Zinc Anode Kit (B23KZ).
Anodes should be inspected at least once per season and replaced when 50% depleted — a fully consumed anode leaves your drive unprotected. For dedicated Bravo II & III coverage, also see: MerCruiser Bravo II & III Anode Kit - Zinc. For Bravo 1 drives, see: MerCruiser Bravo I Anode Kit - Zinc.
