Lewmar 589303 Tube F/185TT 185X6X2000

Upgrade your vessel's propulsion system with confidence using the precision-engineered fiberglass tube designed specifically for Lewmar 185TT tunnel thrusters. Measuring 185mm in diameter, 6mm wall thickness, and a full 2000mm length, this robust component ensures seamless integration and reliable performance in demanding marine conditions.

Why This Fiberglass Tube Stands Out for Marine Thruster Applications

Boat owners and marine professionals know the critical role a high-quality thruster tube plays in maintaining precise maneuvering control. Unlike metal alternatives that can succumb to corrosion from saltwater exposure, this fiberglass construction delivers exceptional resistance to galvanic corrosion, UV degradation, and impact damage. Its lightweight design reduces overall system weight without sacrificing strength, helping optimize your boat's fuel efficiency and handling.

Crafted to exacting standards, the tube provides a smooth interior surface that minimizes friction on the thruster propeller, promoting quieter operation and extended motor life. Whether you're docking in tight marinas, navigating crowded harbors, or compensating for crosswinds during cruising, this tube enhances the 185TT thruster's responsiveness and reliability.

Key Specifications and Design Advantages

• Precise Dimensions: 185mm outer diameter x 6mm wall thickness x 2000mm length – perfect fit for standard 185TT installations.
• Premium Fiberglass Material: High-strength composite for superior durability and weight savings compared to traditional steel or aluminum.
• Seamless Integration: Matches OEM tolerances to eliminate vibration and ensure watertight seals.
• Marine-Grade Resilience: Withstands constant submersion, temperature fluctuations, and mechanical stresses.
• Low Maintenance: Non-porous surface resists marine growth, algae, and fouling for fewer cleanings.

Installation Insights for Optimal Performance

Installing a new thruster tube requires careful preparation to maximize longevity. Begin by thoroughly inspecting the hull cutout for any irregularities, then dry-fit the tube to confirm alignment with your 185TT thruster motor and propeller assembly. Use marine-grade epoxy resin for bonding, ensuring even application around the full circumference to create a bombproof seal.

Pro tip: Incorporate flexible mounting brackets if your hull flexes under load, and always fair the exterior with gelcoat for hydrodynamic efficiency. After installation, run a pressure test to verify integrity before sea trials. This approach not only prevents leaks but also maintains the tube's structural integrity over years of service.

Long-Term Maintenance and Care Tips

To keep your thruster tube performing like new, rinse with fresh water after every outing to remove salt residues. Inspect annually for cracks or delamination, especially in high-impact zones. Avoid abrasive cleaners – a soft brush and mild detergent suffice for routine upkeep. With proper care, this fiberglass tube can outlast multiple thruster rebuilds, making it a smart investment for serious boaters.

Boat enthusiasts upgrading from older thruster models appreciate how this tube simplifies retrofits, restoring factory-fresh precision to bow or stern tunneling systems. Its corrosion-free nature means less downtime and lower ownership costs, freeing you to focus on the joy of being on the water.
