Description

Martyr CMPNZH is a zinc replacement propeller nut anode for Style H applications. Current product listings identify it under LNS SKU 194-CMPNZH and manufacturer part number CMPNZH, and position it as a spare/replacement sacrificial anode for prop nut systems rather than a complete nut assembly.

This anode is designed for salt water use to help protect propeller hardware from galvanic corrosion by sacrificing itself before more valuable underwater metals do. Current sources also note that zinc is not recommended for fresh water service on this part.

Key Features

• Martyr zinc replacement prop nut anode
• LNS SKU: 194-CMPNZH
• Manufacturer part number: CMPNZH
• Style H spare / replacement prop nut anode
• For salt water use
• Commonly associated with 2″ shaft size / H model references in current listings
• Current sources show approximate size around 3.84″ length and 3.34″ outside diameter.

Compatibility / Application
Current listings identify CMPNZH as a Style H replacement propeller nut anode, commonly tied to 2″ shaft size references. Final fitment should be confirmed by the existing prop nut anode style, shaft size, and hardware layout before ordering.

Fitment Notice
Please confirm the existing anode is Style H before ordering. This part is sold as the replacement anode for that system, so matching the style, shaft size, and mounting hardware is the important fitment check.

When This Part Needs Replacement
Replace this anode when:

• the existing prop nut anode has been significantly consumed
• corrosion protection is reduced
• haul-out inspection shows heavy loss of material
• the original anode is cracked, loose, or near the end of service life

Installation Notes

• Confirm Style H fitment before purchase.
• This is a zinc anode for salt water applications.
• Current sources note that fasteners are included with replacement prop nuts, while separate replacement listings may vary by supplier, so checking the exact package contents before shipment is smart.
• One current source notes the nylon patch is intended for one initial application, and recommends thread retention support such as thread locker or Teflon tape for secure installation practice where appropriate.

Parts Desk Insight
With prop nut anodes, the biggest ordering mistake is usually buying the wrong style/shaft size, not the wrong material. If the existing setup is already a Style H replacement system, CMPNZH is the zinc spare anode to match that style. Zinc is the right lane for salt water boats, but it is worth double-checking the boat’s operating environment before finalizing the order.
