2. Informació de seguretat
ADVERTIMENT: Failure to follow these safety instructions could result in serious injury, damage to the product, or damage to the vessel.
- Installation and service should only be performed by qualified personnel or a certified marine technician.
- Always disconnect the vessel's battery power before performing any installation, maintenance, or inspection.
- Ensure all electrical connections are secure, properly insulated, and conform to marine electrical standards.
- Keep hands, hair, and loose clothing clear of the thruster propeller when power is connected.
- Do not operate the thruster out of water.
- Regularly inspect the thruster for any signs of wear, damage, or corrosion.
3. Configuració i instal·lació
The Lewmar TT 185 Thruster requires careful planning and precise installation to ensure optimal performance and safety. Consult the detailed installation guide provided with the product for specific measurements and procedures.
3.1. Comprovacions prèvies a la instal·lació
- Verify the correct thruster model and voltage (12V) for your vessel's electrical system.
- Ensure adequate space is available for the thruster tunnel and motor assembly.
- Confirm the hull material is suitable for thruster installation and can be properly sealed.
3.2. Mounting the Thruster Tunnel
The thruster tunnel must be securely mounted through the hull, typically in the bow or stern. The tunnel should be positioned to minimize hydrodynamic drag and maximize thrust efficiency. Ensure the tunnel is perfectly aligned and sealed to prevent water ingress.
3.3. Motor and Gearbox Assembly Installation
The motor and gearbox assembly are mounted directly onto the thruster tunnel. Ensure all mounting bolts are tightened to the manufacturer's specifications. The propeller should be installed onto the spline drive shaft, ensuring it rotates freely without obstruction.

This image displays the complete thruster unit, featuring the electric motor assembly mounted atop the white tunnel, which houses the 5-blade propeller. The motor unit is encased in a protective white cover with the 'LEWMAR' logo, and electrical connections are visible at the rear of the motor housing. The robust design is evident, highlighting its readiness for marine installation.
3.4. Connexions elèctriques
Connect the thruster to a dedicated 12V DC power supply, ensuring appropriate cable sizing and circuit protection (fuses/breakers) are used. Refer to the wiring diagram in the full installation manual for precise connection details. All connections must be waterproof and corrosion-resistant.
4. Instruccions de funcionament
The Lewmar TT 185 Thruster is designed for intermittent use to assist with docking and maneuvering. It is not intended for continuous propulsion.
- Activació: Turn on the main thruster power switch at the helm.
- Control: Use the dedicated joystick or control panel to activate the thruster. Pushing the control to the left will generate thrust to the port side, and pushing to the right will generate thrust to the starboard side.
- Intermittent Use: Operate the thruster in short bursts (typically 2-3 seconds) to avoid overheating the motor. Allow for cooling periods between prolonged uses.
- Seguiment: Pay attention to any unusual noises or vibrations during operation. If detected, discontinue use and investigate.
5. Manteniment
Regular maintenance is crucial for the reliable operation and longevity of your Lewmar thruster.
- Inspecció anual: Annually inspect the thruster for signs of corrosion, damage to the propeller, and integrity of electrical connections.
- Substitució de l'ànode: The sacrificial anode (if fitted) must be checked and replaced regularly, typically annually or as wear dictates, to protect against galvanic corrosion.
- Neteja de l'hèlix: Keep the propeller and tunnel clear of marine growth and debris. This can be done during haul-out.
- Integritat del segell: Check the gearbox seals for any signs of leakage.
- Connexions elèctriques: Ensure all electrical terminals are clean, tight, and free from corrosion. Apply a suitable marine-grade dielectric grease to protect connections.
