Fitment Notice
Confirm the drive model and serial number, then compare the installed bearing-carrier anode and mounting points before ordering. Select the drive-specific diagram in Mercury Parts Finder. Compatible-part listings show approximate dimensions, but Mercury does not publish an OEM dimensional drawing for this part, so those measurements are not stated as exact specifications here.
When to Replace
Inspect the anode regularly. Mercury recommends replacing a sterndrive anode when about half its metal has been consumed, or sooner if it is cracked, loose, or missing.
Installation Notes
Mount the anode against a clean metal contact surface using the supplied hardware. Do not paint the anode, as a coating can prevent it from protecting the drive.
Technical FAQ
Is this a trim-tab or transom anode? No. This anode mounts at the bearing carrier behind the propeller; trim-tab and transom anodes use different locations.
How do I confirm the correct fit? Match the drive model and serial number to its diagram, then compare the bearing-carrier mounting points.

Parts Desk Insights
Best use: Sacrificial protection for the gearcase at the bearing-carrier area.
Common mistake to avoid: Choosing a trim-tab or transom anode because it looks similar. Those anodes mount in different locations.
Sizing and fitment: Use the drive-specific serial-number diagram and compare the installed anode and mounting points. Approximate compatible-part dimensions are not an OEM specification.
