Lewmar 589351 Replacement Propeller F/185TT Product Description
Engineered for Reliable Performance in Demanding Marine Conditions
Boat owners who rely on their Lewmar 185TT tunnel thruster know that a worn or damaged propeller can compromise maneuvering precision, especially during tight docking situations or in rough waters. The Lewmar 589351 steps in as the direct replacement, restoring your thruster's full thrust power and efficiency. Crafted from high-grade composite materials, it resists corrosion from saltwater exposure and marine growth, ensuring long-term durability without sacrificing hydrodynamic efficiency.
Unlike generic aftermarket options, this OEM propeller matches the original specifications perfectly, including pitch, diameter, and blade design optimized for the 185TT's 185mm tunnel diameter. This means seamless integration, no vibrations, and balanced operation that protects your thruster motor from undue stress.
Maximize Your Boat's Handling and Safety
- Precision Thrust: Delivers consistent forward and reverse power, making low-speed control effortless for single-handed docking or bow/stern adjustments.
- Corrosion Resistance: Built to withstand harsh marine environments, reducing maintenance frequency and extending service life.
- Easy Swap-Out: Designed for straightforward replacement, minimizing downtime during routine servicing or emergency repairs.
- Noise and Vibration Reduction: Smooth blade geometry cuts through water quietly, enhancing onboard comfort during operation.
- Proven Reliability: Backed by Lewmar's engineering for thrusters used on vessels from sportfishers to cruising yachts up to 60 feet.
Investing in the authentic 589351 isn't just about replacing a part—it's about maintaining the responsive handling that keeps you confident on the water, whether you're navigating crowded marinas or anchoring in secluded bays.
Simple Installation Tips for DIY Boaters
Replacing the propeller on your 185TT is a task most owners can handle with basic tools during a haul-out or in-water service. Start by powering down the thruster and securing the boat. Disconnect the shaft key, slide off the old prop, and inspect the shaft for any scoring or debris—clean thoroughly for optimal fit.
Align the new 589351 propeller with the keyway, slide it into place, and torque the nut to manufacturer specs using a calibrated wrench. A dab of marine grease on the shaft prevents future seizing. Test in neutral water before full deployment to confirm smooth rotation. Pro tip: While you're in there, check the zinc anode and seals to prevent costly water ingress.

Prolonging Propeller Life: Essential Care Practices
Regular inspection is key to avoiding premature wear. Dive on the thruster monthly in saltwater or inspect during engine room checks. Look for nicks from debris, fouling from algae, or imbalance signs like unusual noise. Gentle cleaning with a soft brush and eco-friendly antifoulant keeps blades efficient without abrasive damage.
For thrusters in high-use scenarios like charter boats, annual replacement aligns with service intervals. Pair it with a full thruster tune-up: oil changes, seal replacements, and motor brushes for peak performance year-round.
Common Issues and Quick Fixes
Experiencing reduced thrust or grinding noises? A damaged prop is often the culprit. If the 185TT spins but lacks power, entanglement from fishing line or plastic bags could be binding the blades—clear it safely from above deck if possible. Persistent vibration points to imbalance; the 589351's precision molding eliminates this once installed.
Remember, your thruster's gearbox oil level affects prop performance—top up with the recommended synthetic lube during prop swaps.
