Protect Your Boat's Propeller with Quality Prop Anodes
Sacrificial propeller anodes (zinc, aluminum, and magnesium) safeguard boat propellers from galvanic corrosion. Fisheries Supply provides a wide selection of marine anodes and prop nut zincs for both freshwater and saltwater environments.
At a Glance
- Propeller anodes protect against galvanic corrosion by corroding before the propeller itself.
- Use zinc or aluminum anodes in saltwater and magnesium anodes in freshwater.
- Correct sizing ensures proper fit and effective protection.
- Fisheries Supply offers expert guidance, a wide inventory, and reliable shipping.
Understanding Propeller Zinc Anodes
Propeller zinc anodes —often called prop nut anodes or prop anodes —are sacrificial components installed on boat propellers to prevent galvanic corrosion. By corroding first, these anodes protect the propeller’s valuable metals, extending its service life.
Available in multiple sizes and configurations, propeller anodes can be selected to fit your exact propeller shaft and nut dimensions for a secure, effective fit.
Types of Propeller Anodes
- Aluminum and Zinc Anodes: Best for saltwater boating, these anodes provide effective cathodic protection against corrosion.
- Magnesium Anodes: Designed for freshwater environments, magnesium anodes offer stronger galvanic protection where zinc or aluminum may underperform.
Our inventory also includes bronze prop nuts that meet or exceed industry standards for marine durability.
