Shaft Anodes – Zinc & Aluminium Propeller Shaft Protection

Protect your boat's propeller shaft and driveline with premium zinc and aluminium shaft anodes. Our range includes donut, streamlined, 2-bolt, 4-bolt, and heavy-duty shaft anodes in both imperial and metric sizes. Designed for saltwater and brackish water environments, these anodes prevent galvanic corrosion, keeping your shaft, propeller, and stern tube in top condition. Manufactured to meet or exceed US Military Specification MIL-DTL 18001L, our shaft anodes are tried and tested for durability and performance. Suitable for both recreational and commercial vessels, installation is simple and secure. Ensure long-lasting protection with our high-quality shaft anodes from trusted brands and aftermarket replacements.
