The Electrolysis Kit consists of our Aluminum Anode and a strap which fastens the anode to the motor assembly. Electrolysis Kits are recommended for use in extreme saltwater conditions. Aluminum Anodes are a sacrificial metal and protects the Ice Eater from corrosion and electrolysis. Inspect the Aluminum Anode periodically (at least every 2-3 months) for deterioration and/or corrosion. You must replace the Aluminum Anodes when it has been reduced to half of the original size.
