Description

The Yamaha 67C-45251-00-00 is a genuine OEM zinc trim tab bracket anode for select Yamaha outboard applications. It is commonly described as a cube or square style external lower-unit anode that helps protect the gearcase and nearby underwater metal components from galvanic corrosion.

Because this is a zinc anode, it is the correct material choice for saltwater use. Current references also show 63D-45251-10-00 as a superseded OEM number tied to this part family.

Key Features

• Genuine Yamaha OEM trim tab bracket anode
• OEM part number: 67C-45251-00-00
• Zinc sacrificial anode for saltwater use
• Commonly described as a cube / square lower-unit anode
• Helps protect the gearcase and surrounding metal components from corrosion
• Common mounting reference: M8 x 35 mm screw not included on current part-pattern references.

Engine Compatibility
Current fitment references commonly associate 67C-45251-00-00 with select Yamaha outboards including F30, F40, F50, F60, T25, 40MJH, 40MLH, 40TLR, 50EJR, 50TLR, and C40TLR applications. Fitment should still be confirmed by exact engine model and serial number before ordering.

Serial Number Fitment Notice
Fitment should be verified using the Yamaha outboard model and serial number, along with the installed anode shape and mounting pattern. Matching by OEM part number 67C-45251-00-00 remains the safest method.

When This Part Needs Replacement
Replace this anode when it is heavily consumed, pitted, cracked, loose, or significantly reduced in size. External lower-unit anodes should be checked regularly because they are designed to corrode first in order to protect more expensive gearcase components.

Installation Notes
Install on a clean bare-metal mounting surface and do not paint the anode. Confirm the mounting pattern and fastener size before installation. Current part-pattern references indicate the mounting screw may not be included.

Alternate / Superseded Part Numbers when applicable

• 63D-45251-10-00
• CM67C4525100Z

Parts Desk Insight
This style of anode is small, but it protects a much more expensive lower unit. Cube-style external anodes are often easy to miss during routine service, so replacing them before they are badly consumed is a simple way to stay ahead of gearcase corrosion.
