Serial Number Fitment Notice
Anode kit fitment depends on the exact outboard model, horsepower, gearcase/trim assembly configuration, and serial number. Confirm compatibility using the Mercury engine serial number before ordering. Supporting references list Verado 350 / 400 / SeaPro 350 5.7L V10 from serial number 3B266064 and up, and Mercury Racing 400R 5.7L V10 from serial number 3B272594 and up.
When This Part Needs Replacement
Replace the anode kit when the existing anodes are heavily worn, pitted, loose, missing, broken, or reduced significantly from their original size. Anodes should be inspected regularly, especially in saltwater, marina, or mixed-metal environments, because worn anodes can reduce corrosion protection for the outboard.
Installation Notes
Install the anodes in the correct trim, power trim, and transom locations using the supplied hardware. Clean the mounting surfaces so the anodes make proper metal-to-metal contact, and avoid painting over anodes because paint can prevent them from working correctly. Inspect related mounting screws and washer fitment during installation.

Parts Desk Insight
This is the correct style of maintenance kit when servicing corrosion protection on the Mercury 5.7L V10 Verado platform. The important details are the V10 application, aluminum material, and serial-number range—anode kits can look similar, but trim and transom anode shapes vary by engine family and hardware location.
