The Flat Plate Performance Anode Kit by Buckshot Racing #77 is a high-performance replacement for the standard outboard trim tab anode found on many Mercury outboards and MerCruiser sterndrives.
Traditional trim tab anodes are disc-shaped plates with a small fin designed to combat corrosion and reduce torque steer, a common phenomenon in outboard motors. While effective for general use, these fin-style anodes can create clearance issues with larger props and add additional drag in high-performance applications when you run a torque tab.
In performance boating, especially in racing or when upgrading to larger propellers, the factory fin is often removed to reduce drag and increase clearance. The Buckshot Racing flat plate design provides a cleaner hydrodynamic profile, minimizing water resistance compared to either leaving the area open or retaining the factory fin.
This not only improves overall efficiency but also redirects torque steer compensation to the torque tab integrated into the skeg of performance lower units like the Mercury Sport Master and CLE.
To make installation easier, the kit includes a stainless steel Allen head bolt, which allows for convenient top-side access during mounting. This upgrade is especially beneficial in setups where quick access and a secure fit are essential.
The Flat Plate Performance Anode Kit is compatible with most Mercury 2.0L, 2.4L, 2.5L, and 3.0L outboard lower units, covering a broad power range from 40hp to 300hp 2-stroke models. It also fits a variety of MerCruiser outdrives, including R, MR, Alpha One, and Alpha Gen II configurations.
These applications are commonly found in high-speed bass boats, offshore racing boats, and performance fishing setups.
This kit is a direct replacement for multiple Mercury and MerCruiser OEM part numbers, including: 70214Q5, 70214K, 70214M, 46399A1, 76214A6, 31640Q4, 31640T6, 76214Q5, and 76214T1.
