Yamaha - External Anode Maintenance Kit - F150 Corrosion Protection - All Models

Overview

If you’re running an F150 or a 150 horsepower two-stroke, these external anodes are your first line of defense against corrosion. They’re designed to take the hit from electrolysis before it starts eating into your lower unit and bracket.
