Tecnoseal Anode Kit w/Hardware - Mercury Alpha 1 Gen 1 - Magnesium

You may not know it but your sterndrive has anodes to protect it from galvanic corrosion. Now these anodes can last as little as a year or as long as three or four years if the boat is kept on a trailer. The good news is they're not hard to replace and if you can turn a wrench you can do this job. As you can see these anodes are ready for replacement, now make sure you find all the anodes. On the alpha-1 there are six; there's one underneath the prop, there's one on the fin here, there's two on the each trim tab, there's one on the cavitation plate, and there's one way down here on the transom. So anodes come in aluminum, magnesium, or zinc, and we bought a set of aluminum anodes here. Aluminum works best in brackish, fresh, and saltwater so they're usually the all-around best choice. So the right tools, this is an easy job, this anode has only held on by two screws so now we'll replace
