The Martyr CMT-89949 is a zinc bracket / transom bracket anode for select Mercury / Mariner outboard applications. Current listings consistently identify this Martyr part as the zinc version commonly sold as CM89949Z, replacing Mercury 89949A1, and intended for corrosion protection on the outboard bracket assembly in saltwater use.
This style of anode is commonly associated with 150–200 HP Mercury outboard applications in seller fitment references. Published dimensions across current listings are approximately 280 mm length, 59–60 mm width, 58–60 mm height, with 4 fixing holes and about 239 mm hole centers on compatible versions.

Engine Compatibility
Commonly listed for select Mercury / Mariner outboard bracket applications, especially in the 150 HP to 200 HP range. Because bracket hardware and transom bracket configurations can vary by model year and engine family, fitment should be confirmed against your exact engine model and OEM part reference before ordering.
Serial Number Fitment Notice
Please verify fitment using your Mercury 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 that may already have replacement hardware or mixed component history. The supported replacement reference found in current listings is Mercury 89949A1.
When This Part Needs Replacement
Replace this anode when it is heavily wasted, deeply pitted, cracked, loose, or reduced enough that it is no longer offering proper sacrificial protection. Bracket anodes are exposed to harsh underwater conditions and should be inspected regularly on saltwater boats, especially during haul-out, seasonal service, or any time corrosion is found elsewhere on the outboard bracket. The use of zinc indicates this version is intended for saltwater service.
Installation Notes
Install on a clean mounting surface and make sure the anode has good metal-to-metal contact. Do not paint the anode. Hardware inclusion varies by listing, and some current references specifically note that mounting hardware is not included, so confirm included contents before ordering if you need fast replacement.

Parts Desk Insight
This is one of those parts customers often ignore until corrosion is already visible on the bracket. A bracket anode protects a much more expensive assembly, and replacing it on time is far cheaper than dealing with corrosion damage later. Another useful note: this zinc version is the right style for saltwater, while Martyr also offers the same pattern in other materials for different water conditions.
