Thruster Anode Kit - 185TT

Lewmar 185TT Thruster Anode Kit (589350)

A sacrificial zinc anode kit for the Lewmar 185TT bow thruster — protects the bronze hub and surrounding underwater metal components from galvanic corrosion in saltwater.

Why It's Worth It
Galvanic corrosion attacks the most vulnerable metal first — which is exactly what a sacrificial anode is designed for. The 589350 anode corrodes in place of the thruster's more expensive bronze hub and shaft components, protecting them from the electrolytic action that would otherwise eat into those parts over time. The large accessible nut makes in-water replacement straightforward at haul-out or while the boat is still in the water, and the stainless steel sleeve provides optimal retention so the anode stays securely in place through the operating forces of the thruster.

Compatibility Note
For 185TT thrusters fitted with a bronze hub only — composite hub versions do not require an anode. Confirm your thruster's hub material before ordering.

Use
Replace when the anode is heavily wasted, pitted, cracked, loose, or significantly reduced in size. Do not paint the anode — coating it defeats its purpose. Install on a clean, bare metal contact surface. Check at every haul-out.
