The Martyr CM6G54525101Z is a zinc handlebar-style transom bracket anode for select Yamaha outboard applications. It is commonly cross-referenced to Yamaha 6G5-45251-01-00 and is designed to help protect the engine bracket and related underwater metal components from galvanic corrosion in saltwater use.
This is a zinc anode, which makes it the correct material choice for saltwater only. Current fitment references describe it as a transom bracket / handlebar anode used across a broad range of Yamaha outboards, with common published dimensions around 8 in. length, about 1.8–2 in. width, and 2 in. height.

Engine Compatibility
Commonly listed for select Yamaha outboards including applications in the 115, 130, 150, 175, 200, 225, 250, and 300 HP range. Fitment can vary by model year and bracket configuration, so this should be treated as a guide only. Always confirm by OEM number and existing anode shape before ordering.
Serial Number Fitment Notice
Please verify fitment using your Yamaha outboard serial number and current anode shape before ordering. This is the safest way to confirm the correct bracket anode, especially on older engines or units with prior repair history. Matching by 6G5-45251-01-00 / CM6G54525101Z is the best method.
When This Part Needs Replacement
Replace this anode when it becomes heavily wasted, pitted, cracked, loose, or significantly reduced in size. Because this is a zinc anode, it is intended for saltwater service and should be checked regularly during haul-out or seasonal maintenance to keep proper corrosion protection in place.
Installation Notes
Install on a clean bare-metal mounting surface so the anode has full metal-to-metal contact. Do not paint the anode. Current references indicate that mounting hardware is sold separately on some versions, so check your existing hardware before ordering if you need a complete replacement setup.

Parts Desk Insight
This style of anode is easy to overlook because it mounts on the bracket rather than in a more obvious service point, but it protects much more expensive engine hardware around it. One useful detail is that the 6G5-45251-01 pattern has stayed in circulation across a wide range of Yamaha horsepower groups, which makes OEM-number matching especially important when ordering replacement anodes.
