The block anode offers optimal cathodic protection for your OMC and Johnson/Evinrude outboard motor gearbox, reliably protecting the metal components from galvanic corrosion. Specifically designed for OMC 50-140 and Johnson/Evinrude 50-225 hp engines manufactured between 1987 and 1998, this high-quality sacrificial anode ensures a long service life for your gearbox components. Available in zinc for saltwater and aluminum for fresh and brackish water.
As a wear part, the anode absorbs the corrosive processes and thus protects the valuable metal parts of your gearbox. The precise fit and high-quality workmanship guarantee easy installation and reliable function.
