The Martyr CMT-41100276Z is a zinc small plate anode for select Volvo Penta QL bow thruster applications. It is a bolt-on sacrificial anode designed to help protect thruster components and nearby underwater metal parts from galvanic corrosion in saltwater service. Martyr lists the zinc version under CM41100276Z, with published dimensions of 51 mm x 25 mm x 16 mm and a 7 mm hole ID.
This part cross-references to Volvo Penta 41100276. Current fitment references consistently place it on QL bow thruster applications, rather than Volvo Penta SX/DP sterndrive use.
Key Features
- Zinc sacrificial small plate anode
- Martyr part number: CMT-41100276Z / CM41100276Z
- Replaces Volvo Penta 41100276
- Designed for saltwater use
- Published dimensions: 51 mm x 25 mm x 16 mm

Application / Compatibility
Current supported references associate this anode with select Volvo Penta QL bow thrusters, including BP800, BP900, BP1200, and SP1300. Additional marketplace references also associate the same part number with SP900 and some other QL thruster variants, but the strongest consistent fitment support is BP800, BP900, BP1200, and SP1300.
Serial Number Fitment Notice
Fitment should be verified by thruster model, existing anode shape, and OEM part number before ordering. The strongest supported match points are Volvo Penta 41100276 and the QL bow thruster application.
When This Part Needs Replacement
Replace this anode when it is heavily wasted, pitted, cracked, loose, or significantly reduced in size. Bow thruster anodes should be checked regularly because they are designed to sacrifice themselves first in order to protect more expensive thruster components from corrosion damage. Zinc is intended for saltwater use.
Installation Notes
Install on a clean contact surface and do not paint the anode. Hardware inclusion varies across listings: some current references state includes mounting bolt, while others note hardware not included, so stocked contents should be verified before listing or fulfillment.

Parts Desk Insight
This is a small part, but it protects a much more expensive bow thruster assembly. The most important detail on this item is application: current supported references tie it to Volvo Penta QL bow thrusters, not SX/DP drive anodes, so matching by 41100276 and the installed plate shape is the safest way to avoid a bad fit.
