SIERRA 18-6158Z Anode Kit

Compatible Engines

The SIERRA 18-6158Z Anode Kit is a crucial component for protecting your drive from electrochemical corrosion, especially in seawater conditions. Zinc anodes act as sacrificial elements, absorbing aggressive environmental effects and protecting valuable metal parts such as the propeller hub, flange, or gear housing. By using pure zinc, the corrosion process is directed toward replaceable elements rather than the outboard motor structure.

Since precise compatibility data is not available, we recommend verifying fitment by comparing the manufacturer catalog number 18-6158Z with your equipment documentation or OE (original equipment) number. If you have doubts about compatibility with a specific drive type, contact our store support. We are happy to help select the appropriate anode to ensure the safety and longevity of your engine.

Installation and Maintenance

Regular anode replacement is a basic maintenance rule. We recommend checking their condition every season or after 100 hours of operation. Replace them when they have corroded by less than 50% of their original volume. Before installation, ensure that contact surfaces are clean and free of paint to guarantee proper current conductivity.
