The Yamaha gearcase zinc anode F2.5–F6 (2010–) is a genuine zinc anode fitted on the gearcase.
A zinc anode is a sacrificial anode: it is designed to corrode before the engine's other metal parts, protecting them against galvanic corrosion. Inspect the anode regularly and replace it when it is clearly consumed. Never paint or cover the anode, as this impairs its function.
