This zinc rod anode is a direct replacement for Yamaha OEM part 6H1-45251-03 and is also compatible with Selva outboard motors from 25 to 100 HP. Designed to be inserted into the engine’s internal cooling system, this anode protects water passages, cylinder walls, and head components from internal galvanic corrosion. It is especially important in saltwater environments, where electrolysis inside the cooling jacket can cause hidden damage over time.
