The B1KA is an aluminum anode kit for MerCruiser Bravo One sterndrives. Current fitment references consistently describe this kit for 1988 and newer Bravo One drives, and Mercury’s current OEM aluminum kit for the same application is listed for Bravo One drives beginning at serial range 0B664190 and up. This kit is designed to help protect the sterndrive from galvanic corrosion by replacing the main factory anodes as a complete service set.
Because this is an aluminum anode kit, it is the correct material choice for saltwater, brackish water, and mixed-water use. Current product references for Bravo One aluminum kits also consistently position them as the complete corrosion-protection option for Bravo One drives rather than a single-piece replacement.

Engine Compatibility
Fits MerCruiser Bravo One sterndrives. Current fitment references consistently describe Bravo One aluminum kits for 1988 and newer drives, with Mercury’s current OEM reference specifying Bravo One drives from serial number 0B664190 and up. Verify exact drive application before ordering, especially if the drive has had prior repairs or component changes.
Serial Number Fitment Notice
Please confirm fitment using your MerCruiser drive serial number before ordering. This is the safest way to verify the correct Bravo One anode kit, especially since anode kits are application-specific and should match the exact drive configuration already installed.
When This Part Needs Replacement
Replace the kit when the installed anodes are heavily wasted, pitted, cracked, loose, or significantly reduced in size. Current Mercury and aftermarket references both recommend inspecting anodes periodically and replacing them when visible corrosion or pitting shows the protective material has been used up.
Installation Notes
Install the replacement anodes on clean bare-metal contact surfaces and do not paint them. Bravo One kit references consistently describe these kits as including the main drive anodes and attaching hardware for a full service replacement. Before installation, compare the installed anodes on the drive to confirm the kit matches your Bravo One setup.

Parts Desk Insight
A complete Bravo One anode kit is usually the smarter buy than replacing one piece at a time, because corrosion protection works best when the whole drive is maintained evenly. Another useful detail is that Bravo One kits commonly include five main anodes plus hardware, which makes them a practical scheduled-service item for customers maintaining the entire drive at once.
