The Mercury 8M0137814 is a genuine OEM aluminum anti-vent plate anode for select Mercury outboard applications. Mercury’s current product references identify this part specifically as an aluminum anode kit for the anti-ventilation plate, not a trim tab anode.
This is an aluminum anode, making it the correct material choice for saltwater, brackish water, and mixed-water use. Mercury states these aluminum anodes help prevent corrosion on aluminum and stainless-steel engine parts.
Key Features
- Genuine Mercury OEM anti-vent plate anode
- OEM part number: 8M0137814
- Aluminum sacrificial anode
- Designed for the anti-ventilation plate location
- Helps protect exposed engine and lower-unit metal from galvanic corrosion
- GTIN commonly listed as 745061063389.
Engine Compatibility
Current supported fitment references associate 8M0137814 with Mercury 175–300 HP 3.4L V6 and 4.6L V8 FourStroke outboards. Additional current Mercury-linked references also list fitment for 5.7L V10 Verado 350–425 HP outboards from serial 3B266064 and up. Public source support was not found for listing this exact part as a Verado L4 trim tab anode.
Serial Number Fitment Notice
Fitment should be confirmed 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 verify exact diagrams and part numbers.
When This Part Needs Replacement
Replace this anode when it is heavily consumed, pitted, cracked, loose, or significantly reduced in size. Mercury advises inspecting anodes periodically and replacing them when there are visible signs of corrosion or pitting.
Installation Notes
Install on a clean mounting surface and do not paint the anode. Current pattern references note M10 x 25 mm mounting hardware not included on this anti-vent plate anode style.
Alternate / Superseded Part Numbers when applicable
No official superseded OEM number was confirmed in the reviewed Mercury sources for this part. Common cross-reference listings include:
- 8M0137814
- CM8M0137814A
- 00848AL
Parts Desk Insight
The important correction on this part is application: 8M0137814 is an anti-vent plate anode, not a trim tab anode. It is also cataloged as aluminum, so it should be listed as an aluminum anti-vent plate anode unless a serial-number-backed Mercury catalog lookup shows a different application.
