Performance Metals Flat Trim Tab Anode - Aluminum

Flat Trim Tab Anode - Aluminum Used on all large Mercury outboards, Mercruiser Alpha 1 Gen II, and Bravo outdrives. Performance Metals Navalloy aluminum anodes are manufactured to the military specification MIL-DTL 24779 and are suitable for use in all water types- salt, brackish, or fresh. The anode includes the exclusive, patented “red spot” wear indicator. Replaces: Mercury # 76214Q 5 Kit includes mounting bolt and installation instructions., Material: Aluminum 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 BetterPerformance 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.
