We care about marine life so that's why our anodes are free of Cadmium. Found in some other anodes on the market, Cadmium harms sea life and pollutes our fragile marine environment. So remember, Cadmium free is best for the sea!

Why Aluminium?
Most of us are taught to believe that Zinc anodes are the best protection for your outboard. However, if used in brackish or fresh water Zinc anodes can develop a Zinc hydroxide layer after only a few months which renders the anode useless. Aluminium, on the other hand, is a far more active metal deeming Aluminium anodes the smartest choice for protection of your outboard in all types of water.

Review Mercury Mariner 25-60hp Aluminium Trim Tab

By: on 25 February 2019
Very happy with the trimming results from this product. As far as the sacrificial anode application, time will tell if this is superior than a zink option. Overall I would recommend this product and was very happy with the service provided by Outboard Spares.
