What Are Marine Anodes?
Marine anodes are sacrificial metal components that corrode first, protecting critical underwater parts such as propellers, shafts, trim tabs and engine cooling systems. By attracting galvanic corrosion, anodes prevent damage to expensive marine components.
Zinc vs Aluminium Anodes
- Zinc anodes – Ideal for saltwater environments.
- Aluminium anodes – Suitable for saltwater and brackish water with longer lifespan.
Selecting the correct material is essential for effective corrosion protection in your boating environment.
