Lewmar 589350 Anode Kit For 185TT

The Lewmar 589350 Anode Kit For 185TT is a sacrificial anode assembly engineered to protect your thruster system from galvanic corrosion in saltwater and brackish marine environments. This kit is essential for boat owners and marine technicians who operate Lewmar 185TT thrusters, where electrolytic corrosion poses a serious threat to thruster longevity and performance. Sacrificial anodes work by corroding preferentially in place of the more valuable thruster components, effectively extending the operational life of your marine propulsion system.

The 185TT thruster system relies on a complete anode protection strategy to prevent corrosion of its stainless steel and aluminum wetted surfaces. The Lewmar 589350 kit delivers sacrificial zinc or aluminum anode material specifically formulated to corrode at a predictable rate, creating an electrochemical barrier that shields the thruster housing, propeller, and internal components from saltwater attack. Weighing 2 lbs, this replacement anode kit maintains proper cathodic protection levels when installed according to Lewmar specifications, ensuring your thruster continues operating at peak efficiency throughout the boating season.

Routine anode replacement is critical maintenance for any vessel equipped with a Lewmar 185TT bow or stern thruster, particularly those in saltwater service. Most marine technicians recommend inspecting anode condition annually and replacing the kit whenever anode material has depleted by 50 percent or more. This Lewmar 589350 kit is a direct-fit replacement that requires no modification to your existing thruster installation—simply remove the spent anode assembly and install the new kit following the manufacturer's guidance to restore full cathodic protection.
