Mercury I/O Martyr Anode Boater's World is your Sacrificial Anode Center. We want to make sure engine troubles don't keep you from having fun on the water! No matter where you choose to do your boating, we have all the right products to help take care of your boat. Read this quick overview on how to protect you engine from corrosion!What causes corrosion? Seawater is a good conductor and freshwater a bad conductor, so corrosion is worse in seawater. Generally, corrosion rates increase in proportion to the amount of oxygen in the water. However, cracks and crevices, which are areas starved of oxygen, become anodic and corrode also. Higher temperature increases corrosion rates - doubling for every 30 degrees C (55 degrees F). There are various types of microorganisms that can contribute to corrosion, either by removing protection or causing a corrosive environment.Why do I need anodes? You need anodes on your engine because when two different metals are in contact, electrons will flow from the more negatively charged metal (anode) to the more positive metal (cathode). If you want to protect both types of metal from corrosion, you must add a third metal such as zinc, although magnesium and aluminum are also used. This active metal becomes the anode for both metals. The zinc or aluminum sacrifices itself to protect the other two metals, hence the term "sacrificial anode".Do's and Don'tsDO change your anode when they are 50 percent corroded DO make sure they make good electrical contact - remove paint and clean the mounting surface.DO protect trim tabs individually (do not bond). Although they are usually made from stainless steel they can still corrode and need sacrificial anodes.DO be sure to use new fasteners on sterndrives - even stainless bolts fail as a result of corrosion.DO keep a sterndrive immersed in the water so that the anodes can work. DON'T use zinc anodes on aluminum outdrivesDON'T paint anodes. They will not work to their full potential!DON'T mix anode types - aluminum anodes will try to protect zinc.DON'T use magnesium anodes on outdrives in salt or brackish water as it will "overprotect" the aluminum.

Aluminum Anode Performance Metals Premium Aluminum Sacrificial AnodesAll metals immersed in an electrolyte, like sea water, produce an electrical current. When two dissimilar metals are in contact they produce a galvanic cell (like a battery), with the less noble metal (like Aluminum or Zinc) forming the anode and the more noble metal (such as Stainless Steel) forming the cathode. The anode sacrifices itself by corroding, or giving up metal to protect the cathode - hence the term sacrificial anode.Why Are Performance Metals Premium Anodes Better?Performance Metals anodes are made from Aluminum/Indium alloy. This Aluminum/Indium alloy is more active, providing better protection than traditional Zincs. Aluminum anodes are essential for Mercury stern drives as Zinc does not provide sufficient protection. Mercury recommends aluminum anodes for both salt and freshwater on their stern drives. Aluminum anodes last 40 percent longer than zinc anodes. Plus, Aluminum anodes self-clean in fresh water while Zinc anodes form a coating that limits their effectiveness within a few months. Performance Metals premium aluminum anodes include the required hardware for mounting.
