The Martyr CMT-589150Z is a zinc bow thruster anode for Lewmar 140TT thruster applications. It is designed to help protect the thruster and nearby underwater metal components from galvanic corrosion in saltwater service. Current references tie this part to Lewmar 589150 and the 140TT / 140 mm tunnel thruster application.
This is a zinc anode, making it the correct material choice for saltwater use. Current kit references also note features such as a steel insert for retention and service life, while Martyr and Lewmar references consistently place this anode in the 140TT family.
Key Features
- Zinc sacrificial thruster anode
- Fits Lewmar 140TT thruster applications
- Cross-referenced to Lewmar 589150
- Designed for saltwater use
- Commonly associated with 140 mm tunnel diameter thrusters
- Current kit references note a steel insert for retention and service life
Application / Compatibility
Fits Lewmar 140TT bow thrusters and current references describe it for 140 mm tunnel diameter thruster applications. Matching by the 589150 / CMT-589150Z reference and current installed anode style remains the safest fitment method.
Serial Number Fitment Notice
Fitment should be confirmed by thruster model, current anode shape, and OEM reference number before ordering. The strongest supported match points are Lewmar 140TT and 589150 / CMT-589150Z.
When This Part Needs Replacement
Replace this anode when it is heavily wasted, pitted, cracked, loose, or significantly reduced in size. 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.
Installation Notes
Install on a clean contact surface and do not paint the anode. Current references vary on hardware details: some describe the kit as including mounting hardware, while others list the anode only, so included contents should be verified against the exact source item being stocked or ordered.

Parts Desk Insight
Bow thruster anodes are small parts that protect a much more expensive thruster assembly. One useful detail on this part family is that the 140TT application is commonly sold both as an anode-only replacement and as a kit, so matching the stocked version to the needed contents helps avoid installation delays.
