The Race Anode Plate Bracket from Buckshot Racing #77 replaces the genuine Mercury Marine and Mercury Racing OEM part number 89949 A1. This anode bracket is designed for the Mercury V6 High-Performance and Pro Max outboard engines, including the 150 HP, 175 HP, 200 HP, 225 HP, 250 HP, 275 HP, 300 HP, and 300X/XS/Drag series.
 
It is compatible with 2.0-liter, 2.4-liter, and 2.5-liter Mercury Racing configurations and the 3.0-liter XS and Pro Max families, covering popular models such as the 150/200 Pro Max Super Mag, 225 Pro Max, 250 HP XS, 250 HP Sport XS, 280 HP ROS, and 300 Drag. The anode is also used across many Sportmaster and Torquemaster gearcases that form the foundation of Mercury’s performance line.
 
This anode plate assembly performs two essential functions.
 
First, it protects the engine’s metallic components from galvanic corrosion, which occurs when dissimilar metals in contact with water create an electrochemical reaction. The anode is made of a more reactive alloy, intentionally designed to corrode before any structural components do—hence the term sacrificial anode.
 
Second, this bracket adds stability and rigidity to the transom and mid-section, providing a firm connection point that helps absorb engine torque and maintain proper alignment under race-level stresses.
 
The Buckshot Racing #77 replacement anode plate is manufactured to Mercury Racing’s original specifications. The alloy composition is chosen to ensure effective corrosion protection without compromising the mechanical strength needed to support the mid-section and clamp brackets of high-output engines. This combination of electrical reactivity and structural integrity makes it suitable for all Mercury V6 EFI, Pro Max, Super Mag, XS, and Offshore models operating in both freshwater and saltwater conditions.
 
The anode plate bracket fits a wide range of high-performance outboards, including the 150 HP and 200 HP Pro Max Super Mag, the 225 EFI Pro Max and Super Mag, the 250 HP XS and HP Sport XS, the 260 ROS, the 280 HP Hi-Perf 2.5L, the 300 Drag, the 300 X and 300 XS 3.0L EFI Pro Max series, and even the latest Mercury Racing 300R V8 4.6L 4-stroke platforms.
 
In each of these applications, the anode plate bracket plays the same critical role—protecting the lower unit, transom bracket, and mid-section from long-term corrosion damage while maintaining the geometry of the motor mount system.
 
Each Buckshot Racing #77 Mercury V6 Race Anode Plate Bracket is supplied ready for installation as a direct-fit replacement for Mercury OEM 89949A1. It is a practical, durable, and performance-correct component for maintaining the structural and electrochemical integrity of Mercury V6 outboards from the Pro Max through the XS and 300 Racing lines.
 
This part ensures that the outboard’s high-strength components remain protected, allowing Mercury’s race-bred engines—from the 150 Pro Max to the 300 Drag and 300 XS—to continue operating at peak performance without compromise.
