Sierra Zinc Anode Kit for Mercruiser, 18-6159Z

The Sierra Zinc Anode Kit, part number 18-6159Z, is a sacrificial anode kit made of zinc, designed to protect Mercruiser engine and drive components from galvanic corrosion. Zinc anodes work by corroding in place of surrounding metal parts, giving critical engine and drive hardware a longer service life in the water. This kit is categorized for Mercruiser applications, making it a straightforward replacement option for boat owners maintaining their Mercruiser-equipped engine or drive setup.

Replacing anodes on a regular maintenance schedule is one of the most cost-effective ways to prevent expensive corrosion damage to engine and drive components. This kit ships as a complete set, sized and configured for the Mercruiser fitment listed under this part number, so there is no guesswork in matching individual anode pieces.
