Shaft Anodes made of Mil-Spec Aluminum Alloy.
- For use in all types of water: salt, brackish and freshwater.
- More active than zinc.
- Self-cleaning performance.
- The world's most popular family of aluminum shaft anodes.
Highly recommended as an alternative to zinc anodes for all boats, and especially those that operate in brackish or fresh water.
All anodes have interlocking halves and extra alloy around the fastener. Models X-1AL thru X-9AL have two stainless steel allen screws, and models X-10AL thru X-19AL have four. Stainless steel nuts are pressed in, and plastic retaining washers ensure that the screws do not fall out during installation.
