Martyr CMT-Z03SZ is a zinc hull strap anode designed for weld-on hull and structure protection in saltwater service. This semi-streamlined strap-style anode is used to help protect hulls, rudders, trim surfaces, and other bonded underwater metal areas from galvanic corrosion. Martyr’s CMZ03 series is identified as a weld-on streamlined hull anode, and sellers commonly list this zinc version with steel straps. Zinc material is intended for saltwater use only.

Engine Compatibility
This is not an engine-specific anode. It is a hull/structure anode selected by size, material, strap configuration, and installation method rather than by engine model. Fitment should be confirmed by overall dimensions, strap style, mounting method, and the metal surface being protected.
Serial Number Fitment Notice
Fitment should be confirmed by application, dimensions, and strap or mounting layout rather than by engine serial number alone. Match the existing anode length, width, thickness, strap style, and installation method before ordering.
When This Part Needs Replacement
Replace when the zinc is significantly wasted, cracked, loose, or no longer maintaining proper protective mass. Hull anodes should be inspected regularly and replaced before they are fully consumed so bonded underwater metals remain protected. Zinc is the correct material choice for saltwater applications.
Installation Notes
Install on a clean, properly prepared mounting surface so the anode can maintain effective electrical contact. This is a weld-on strap-style hull anode. Martyr notes that bolt holes can be added on straps as required, and that inserts and straps are available in either aluminum or steel depending on configuration. Confirm the exact strap style needed for the application before ordering.

Parts Desk Insight
Hull strap anodes are application-based rather than engine-based. The safest way to match this style is by the anode’s overall size plus strap configuration and installation method. Several current listings describe CMZ03SZ as a 12" x 3" zinc weld-on hull anode with straps, while some list the actual height closer to about 1.37", so the 1-1/4" callout is best treated as the nominal catalog size.
