The Mercury Marine 80287855 Corrosion Guard Heavy Duty is a genuine Mercury OEM corrosion inhibitor specifically formulated to protect marine engines, sterndrives, outboards and exposed metal components from rust, oxidation and saltwater corrosion. Designed for harsh marine environments, it creates a durable water-resistant protective barrier that seals out moisture, salt and air while remaining safe for use on both painted and unpainted surfaces.
Unlike conventional sprays, Corrosion Guard forms a clear protective film that dries to the touch and provides long-lasting protection without becoming sticky. It is ideal for protecting lower units, outdrives, trim and tilt systems, exposed electrical connections, mounting brackets and other metal components susceptible to corrosion.
Mercury recommends Corrosion Guard as part of routine maintenance for both freshwater and saltwater boats. It is particularly effective for protecting under-cowl components, powerheads, trim motors and exposed hardware during storage and between uses. The product can also help prevent corrosion from spreading in areas where paint damage, blistering or undercutting has already occurred.
