The Yamaha trim tab zinc anode F20–F50 is a genuine zinc anode fitted in place of the trim tab 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.
