Aluminum Alloy Anode (AL-Zn-In) and Securing Screws for lower unit SRV retract thrusters

Securing screws are included. If you require additional replacement screws, please add a note in the checkout process with the quantity of extra screws required.


  • The mil-spec alloy includes about 5% Zinc and a trace of Indium to prevent oxidation resulting in a layer reducing the sacrificial properties of the anode.
  • Provides more protection and will last longer than zinc anodes of the same size (up to 50% longer).
  • Less than half the weight of of a similar sized zinc anode.
  • Provides superior support compared to zinc anodes in fresh or brackish water, while still giving excellent pro­tection in salt water, and is the only anode that is safe for all applications.
