Lewmar 589350 Anode Kit For 185TT

Protect your boat's thruster system from the harsh effects of saltwater corrosion with the Lewmar 589350 Anode Kit, precision-engineered for the 185TT thruster range. Sacrificial anodes play a crucial role in marine environments, acting as the first line of defense by corroding in place of vital metal components like the propeller, gear housing, and motor shaft. This zinc-based kit ensures long-term reliability, helping prevent costly repairs and keeping your vessel maneuvering smoothly even after extended exposure to saline waters.

Why Sacrificial Anodes Matter for Your 185TT Thruster

In saltwater, galvanic corrosion accelerates rapidly due to the electrolyte-rich environment, where dissimilar metals create electrical currents that eat away at unprotected parts. The Lewmar 589350 kit deploys high-purity zinc anodes that sacrificially corrode at a controlled rate, shielding your thruster's aluminum or bronze components. Unlike generic replacements, this OEM kit matches the exact specifications for seamless fit and optimal protection, maintaining thruster efficiency and torque output.

Boat owners often overlook anode maintenance until performance dips—such as reduced thrust or unusual vibrations. Regular inspection reveals pitted or eroded anodes as early warning signs, allowing proactive swaps to avoid downtime during critical cruises.

Key Advantages of the Zinc Construction

• Ideal for Saltwater Use: Zinc's electrochemical properties provide superior protection in marine salt environments compared to magnesium (freshwater) or aluminum (brackish/mixed) alternatives.
• Robust Durability: Engineered with premium materials for steady performance, resisting premature failure under demanding conditions like tidal currents or prolonged anchoring.
• Complete Kit Convenience: Includes essential washers and nuts for secure, hassle-free installation without sourcing extras.
• Trusted Lewmar Quality: Backed by rigorous testing to deliver consistent reliability, minimizing electrical imbalances that could harm your thruster.

Simple Installation and Maintenance Tips

Replacing anodes on your 185TT thruster is straightforward, typically requiring basic tools like a wrench and marine grease. Begin by powering off the system and cleaning the mounting area to ensure good electrical contact. Secure the new anode with the provided hardware, torque to manufacturer specs, and apply anti-seize compound to bolts for future ease.

1. Inspect anodes every 6-12 months or after 100 hours of thruster use in saltwater.
2. Replace when more than 50% eroded to maintain protection levels.
3. Monitor your boat's bonding system and shaft grounds for comprehensive cathodic protection.
4. Pair with a reference electrode check for precise anode efficiency readings.

These steps not only extend thruster lifespan but also enhance safety and resale value for your vessel.

Perfect Fit for 185TT Thruster Owners

Designed exclusively for Lewmar's 185TT series bow and stern thrusters—popular on mid-sized yachts and sailboats—this kit restores factory-level corrosion resistance. Whether you're retrofitting after heavy use or performing seasonal maintenance, it integrates flawlessly without modifications.

Invest in Peace of Mind for Your Marine Adventures

Choosing the Lewmar 589350 means prioritizing proven protection over risky shortcuts. Keep your 185TT thruster operating at peak performance, dive deeper into worry-free boating, and focus on the horizons ahead.
