Boat owners with Evinrude or Johnson outboards, this anode kit is essential maintenance for saltwater or brackish water use! The 338635 anode is specifically designed for 8, 9.9 and 15 HP 4-stroke outboards from 1993-2001. Made from aluminum, this sacrificial anode measures 1.5 inches tall, 1 inch wide, and 0.5 inches thick with a 0.25 inch mounting hole. If you're operating in saltwater or brackish conditions, having a properly functioning anode is crucial for protecting your lower unit from galvanic corrosion. This anode essentially sacrifices itself to protect the more expensive metal components of your outboard. The installation is straightforward if you're mechanically inclined - just replace the old, corroded anode with this new one. Regular anode inspection and replacement is one of those simple maintenance tasks that can save you from costly repairs down the line. The quality matches OEM specifications, ensuring proper fit and protection for your specific engine model. Whether you're a weekend fisherman, recreational boater, or marine professional, keeping your anodes in good condition is basic preventative maintenance that extends the life of your outboard. This kit gives you exactly what you need to keep your Evinrude or Johnson running strong season after season. Don't wait until you see corrosion damage - replace your anodes regularly and boat with confidence!
