Lewmar 00589350 Sacrificial Zinc Anode Kit for 185TT Bow Thruster

The Lewmar 00589350 Anode Kit is a genuine replacement sacrificial zinc anode kit designed specifically for Lewmar 185TT tunnel bow thrusters with a 185mm tunnel diameter and bronze hub. This anode provides essential cathodic (galvanic corrosion) protection for the thruster's underwater metal components, sacrificing itself to prevent corrosion of more critical parts in saltwater environments.

Key Features:

• Sacrificial zinc anode — zinc alloy construction rated for saltwater use
• Stainless-steel sheath/insert for optimal retention and extended service life
• US Mil-Spec 18001K alloy zinc construction
• Secured with a large, accessible nut — designed to be replaceable with the boat in the water
• Kit includes anode, washer, and lock nut — everything needed for installation
• Compatible with all Lewmar 185TT thruster models fitted with a bronze hub
• Manufactured to Lewmar OEM specifications

Inspect the anode every few months and replace it once more than half its mass has been consumed. Installation requires a 17mm wrench or socket. For brackish or freshwater applications, consider the magnesium variant (589350-MG).
