- Description
The MARTYR Prop Nut Anode is a specialized sacrificial anode designed to fit directly onto the propeller nut or propeller shaft assembly, providing targeted protection against galvanic corrosion. It is widely used on inboard and sailboat propulsion systems, especially where space is limited near the propeller hub.
Manufactured using high-purity zinc, aluminum, or magnesium alloys, these anodes ensure efficient corrosion protection and long service life in marine environments.
Key Features
- Nut-Mounted Design: Fits over or replaces the propeller nut, ensuring direct protection at a critical corrosion point
