25-30HP Anode - 804043 This anode is designed to protect your Mercury or MerCruiser engine or outdrive from corrosion due to electrolysis. Anodes are essential for extending the lifespan of the engine and other metal components in marine environments, especially in saltwater, where corrosion is a more significant concern. Replacing anodes on a boat is crucial because they act as "sacrificial" metals, designed to corrode and dissolve instead of the other metal components on your boat, like the propeller and hull fittings, protecting them from galvanic corrosion which can cause significant damage if left unchecked. For: 25-30HP EFI 3 Cyl. 4-Stroke Mercury Outboards
