The Martyr CMT-PNZF is a zinc replacement propeller nut anode in the F-style pattern, designed to help protect propeller shafts and propellers from galvanic corrosion in saltwater service. Current product references identify it as the replacement zinc only, rather than a complete assembled prop nut kit.
Key Features
Zinc sacrificial propeller nut replacement anode.
Martyr part number: CMT-PNZF / CMPNZF.
F-style replacement anode pattern.
Designed for saltwater use.
Current F-pattern references commonly associate this replacement size with 1-1/2 in. shaft applications.
Application / Compatibility
Suitable where an F-style replacement prop nut zinc is required. The safest match points are the existing prop nut style, shaft size, and replacement-anode pattern rather than appearance alone. Current category references place the F replacement in the 1-1/2 in. shaft-size group.
Fitment Notice
Fitment should be confirmed by the installed prop nut assembly and replacement-anode pattern before ordering. Matching by CMT-PNZF / CMPNZF / PN-F-ZN remains the safest method.
When This Part Needs Replacement
Replace the anode when it is heavily wasted, pitted, cracked, loose, or significantly reduced in size. As a zinc anode, this version is intended for saltwater corrosion protection.
Installation Notes
Current Martyr replacement prop nut references state that fasteners are included with replacement prop nuts. They also note the nylon patch is intended for one initial application only, and thread retention should be confirmed during installation. Install on a clean contact surface and do not paint the anode.

Parts Desk Insight
The important detail on this part is that it is the replacement anode for the F-style prop nut system, not the full complete assembly. Matching the installed prop nut style first is the best way to avoid ordering the wrong replacement zinc.
