The prop nut anodes are designed to be used with an adapter assembly that can be easily screwed to the shaft to successfully place prop nuts (and just as easy to replace). Great for use on Sterndrives and Outboards too! The stainless steel inserts improve grounding and ensure the nut holds fast.

Designed by Sea Shield Marine and made in the USA, these aluminum anodes conform to Mil-Spec MIL-A-24779, providing the world’s best cathodic protection for your shaft and propeller.
