The Mercury 8M0205955 is a genuine OEM aluminum anode kit for select Mercury 4.6L V8 250–300 HP outboards and Mercury Racing 250R / 300R Verado applications. Mercury identifies this kit as corrosion protection for the outboard and lists it as including the square plate, all trim and trim manifold aluminum anodes, plus hardware.
Because this is an aluminum anode kit, it is the correct material choice for saltwater, brackish water, and mixed-water use. Mercury’s current OEM listing specifically describes it as an aluminum kit for these V8 Verado-family applications.

Engine Compatibility
Supported fitment from Mercury’s official listing includes Mercury 4.6L V8 250–300 HP outboards and Mercury Racing 250R / 300R Verado outboards. Fitment should still be confirmed against the exact engine serial number before ordering.
Serial Number Fitment Notice
Fitment should be verified using the Mercury engine serial number in the Mercury Parts Catalog. Mercury’s official parts support directs owners to search by model or serial number to confirm exact diagrams and part numbers.
When This Part Needs Replacement
Replace the kit when the installed anodes are heavily consumed, pitted, cracked, loose, or significantly reduced in size. Anodes are sacrificial corrosion-protection parts and should be kept in serviceable condition so they can continue protecting the outboard from galvanic corrosion.
Installation Notes
Mercury describes this kit as easy to install with existing hardware and common tools. Install on clean contact surfaces and do not paint the anodes.
Alternate / Superseded Part Numbers when applicable
No official superseded part number was confirmed in the current Mercury sources reviewed. The supported OEM part number is 8M0205955.
Parts Desk Insight
This kit is a smart maintenance item because it covers multiple corrosion-protection points on the engine in one OEM package instead of replacing individual pieces one at a time. Another useful detail is that Mercury specifically calls out the trim and trim manifold anodes in this kit, which helps confirm it is built for broader protection than a single anode replacement.
