Important Information About This Manual

Throughout this manual, you will see safety and product damage warnings. You must follow these warnings carefully to avoid possible injury or damage.

2 - Safety Notice

WARNING!

General

Please ensure that you thoroughly understand the operation and safety requirements of the thruster before commencing the installation. Only persons who are completely familiar with the controls and those who have been fully made aware of the correct use of the thruster should be allowed to use it. If there is any doubt of how to install or operate this unit please seek advice from a suitably qualified engineer.

• Please ensure that you thoroughly understand the operation and safety requirements of the thruster.
• Your thruster should not be operated close to swimmers, as a powerful suction of water is generated when in use.
• The tunnel installation and any hull modifications should only be carried out by a specialist. This manual is based on a GRP tunnel installation.
• We recommend that a qualified person install the thruster. Faulty installation will place the boat and crew in danger and make the warranty invalid.
• It is the unavoidable responsibility of the owner or master or other responsible party to assess the risk of any operation on the vessel.

Thruster Supply

The thruster is securely packed for transit. However all parts should be inspected for signs of damage before installation. If any parts are found to be damaged please contact Lewmar.

Fitting

• This equipment must be installed and operated in accordance with the instructions contained in this manual. Failure to do so could result in poor product performance, personal injury and/or damage to your boat.
• Electric thrusters must be located in a dry environment. Should there be a need to install in a damp/wet location then the IP (Ignition Protected) version must be used.
• Electric bow thrusters use powerful electric motors; it is very important that there is sufficient battery capacity and large enough cables for safe operation. Using smaller than recommended battery and cables will cause loss of performance and may cause dangerous overheating.
• Electric motors spark and run hot. Do not place near flammable or sealed areas.
• Main battery must not be connected and power must not be switched on until all covers and terminal protectors are correctly fitted.
• It is very dangerous to run the thruster out of the water, even for a few seconds; the motor will over speed by 300%, causing damage to the motor seals etc. and the propeller will cause serious damage to whatever comes into contact with it. This action will invalidate the warranty.
• Consult the boat manufacturer if you have any doubt about the strength or suitability of the mounting location.

Electrical

• Make sure you have switched off the power before you start installing this product.
• If in doubt about installing electrical equipment please seek advice from a suitably qualified electrical engineer.

This manual forms part of the product and MUST BE RETAINED along with, OR incorporated into, the Owner's Manual for the vessel to which the thruster is fitted.

3 - Installation

3.1 Choosing the location

A competent, marine engineer must carry out any work on the hull of your boat.

The boat MUST be out of the water, levelled and secure in its cradle.

The actual position of the Thruster will depend on the internal & external construction of the Motor Boat or Sailing Yacht. For optimal performance the Thruster should be mounted within the following:

• As far forward as possible (Fig 3.1.1 / lever effect).
• 1 x tunnel diameter below the waterline to prevent air being sucked into the tunnel. (Fig. 3.1.2 / 0.75 x tunnel diameter minimum).
• Minimum suggested tunnel length 2 x tunnel diameter.

NOTE: Ensure there is sufficient space for the Thruster assembly complete with motor and controls in the boat.

Diagram Description (Fig 3.1.1): Illustrates optimal thruster placement relative to the hull, showing forward placement and a minimum distance below the waterline.

Diagram Description (Fig 3.1.2): Depicts the tunnel installation, showing required clearance below the waterline and minimum tunnel length relative to tunnel diameter (Ø).

Tunnel Dimensions

The recommended tunnel is designed to fit a Lewmar saddle, take the weight of the Thruster and the torque of the motor.

Diagram Description (Fig 3.1.3): Shows how altering the tunnel entrance (with a radius 'r = 0.1 Ø') can improve thrust and reduce noise.

3.2 Preparing the hole for the tube

For general guidance for GRP boats only. Problems caused by faulty installation of the tunnel are the installer's full responsibility.

When you are satisfied the best location for the Thruster unit has been found within the parameters available, proceed as follows:

• Diagram Description (Fig 3.2.1): Illustrates creating a jig to precisely align the drill holes either side of the hull, and drilling a pilot hole.
• NOTE: Double check everything before drilling.
• Drill a pilot hole in both sides of the hull.
• Form a wire guide to the diameter of the tunnel hole, mark, check, and cut.
• Insert the tube into the hole, mark, and remove excess.
• Grind off gel coat etc. Insert tunnel and fix, allowing enough room inside for saddle location on the tunnel.
• Gel coat finished installation and anti-foul.

3.3 Preparing for fitting the thruster

The Thruster can be installed at any angle within 90° from vertical.

Electric motors must be supported if installed more than 30° from vertical (Fig 3.3.1).

4.5 Correct cable sizes

NOTE: Cable length is total from battery to thruster and back.

• Battery crank capacity should be at least equal to the thruster current.
• Main power cables should be run from the batteries and must have an in-line fuse fitted.

Cable sizes based on typical usage:

• Motor thermal trips must be wired in as specified in the product manual.
• The circuit must be protected by the recommended thermal circuit breaker.
• These figures are provided as guidance only; please seek professional assistance where required.

The installation MUST have a battery switch that is switched off whilst the thruster is not in use or the boat is unoccupied.

The cables should be terminated with a ring terminal corresponding to the motor studs, 8 mm (5/16") for 140TT and 10 mm (3/8") for 185TT, 250TT and 300TT. It is important that this termination is secure so that the high current is transferred to the motor efficiently. The minimum voltage at motor when running should be 10V for 12V and 21V for 24V units.

Ensure the insulating boots, supplied with the unit, are correctly fitted.

NOTE: If very large cables are used, discard supplied boots and fit appropriate sized ones.

24V Cable Size Guide

4.6 Electrolytic test

To prevent electrolytic corrosion or faults, the thruster motor body and assembly MUST remain isolated from any power supply or grounds. The installer can check for this using a multimeter in the following ways.

Test 1. Fig 4.7.1

With the negative not connected and the positive cable connected but with battery switch off or fuse removed. Use a continuity tester to check for a connection between the -VE stud and motor body and also between +VE stud and motor body. In both cases the meter should give no indication of an electrical connection.

If a connection is measured between the +VE stud and the motor body, check installation for cables or wires touching the assembly or for damage to assembly.

If a connection is measured between the -VE stud and the motor body, remove any bonding straps attached to the assembly and check as before.

Test 2. Fig 4.7.2

With the battery applied: Use a voltmeter to test the voltage between the –VE motor stud and the thruster motor body. If the supply voltage (12V / 24V) is measured, disconnect power immediately and inspect the assembly for faulty installation or damage.

Diagram Description (Fig 4.7.1 & 4.7.2): Illustrates methods for performing electrolytic tests using a multimeter.

4.7 Installing control panel - all models

A 63.5 mm (2½") hole saw is required. Ensure there is sufficient depth for the control panel and access for the switch leads and plug (see saw template).

The panel has a pre-installed seal and is secured with the 4x screws included in the packaging.

The small plug connects at the panel. If two or more panels are installed, use the optional Y connectors (Sec 6.6).

The auxiliary wire is used to connect an automatic battery switch. Please refer to the units instructions. If automatic battery switch is not fitted, disregard auxiliary wire.

Diagram Description (Fig. 4.7.4): Shows control panel mounting screws and optional Y connectors.

4.8 Final checks

Check the power is OFF.

The thruster must not be operated unless it is in water.

Check list electrical

• Check motor connections are tight with rubber boots in place.
• The correct fuse is in place.
• Check all switch wires are connected to correct motor terminal.
• Now the cables can be connected to the battery.
• Perform electrical check, Section 2.8.

Operation of electrical unit

• Ensure batteries are fully charged before switching on the main power.
• When first operating the thruster, make sure you are not close to other vessels.

4.9 110TT 1.5kW to 300TT 15kW Operation and safety features

Turning system On/Off

• To turn the system on, press and hold the ON button for 1 second. If the system is active, the panel LED will turn green.
• To turn the system OFF, press the ON button once. The system will turn off immediately. The LED will switch off.
• If the system is in fault mode (Solid RED LED), pressing the ON button will turn the system off.

Safety Features

• If the thruster is operated constantly in one direction for more than 3 minutes, the system will enter fault mode. When in fault mode, the control panel LED will turn RED.
• If the system is receiving a PORT/STBD signal when turning the system on, the system will enter fault mode. When in fault mode, the control panel LED will turn RED. This prevents the thruster from unintentionally activating during start-up due to a wiring fault, or a second joystick accidentally being operated.
• If PORT and STBD signals are received simultaneously, then the system will stop thrusting.
• The system will automatically power down after 15 minutes of inactivity for TT, & 5 minutes for RT thrusters.
• When changing thrust instantly from PORT to STBD / vice-versa, there will be a short delay to allow the propeller to come to rest before acceleration in the opposite direction.
• The thruster motor is fitted with a thermal switch to prevent thruster activation if the motor overheats. If the motor temperature is too high, the system will stop operating and the panel LED will FLASH RED. Once the motor returns to a safe temperature, the LED will turn GREEN and thruster operation can recommence.
• The system will detect if the battery voltage is low and indicate this by turning the control panel LED AMBER. This is for indication only and will not affect thruster performance.

5 - Servicing your thruster

5.1 Service schedule

Thrusters are more likely to attract 'debris', so it is necessary to regularly check the tunnel.

New install:

• The anode should be checked after approximately 3 - 4 months to gauge an appropriate replacement schedule.

At the annual boat service:

• Remove any debris from tunnel, propeller and hub.
• Replace the anode.
• If the propeller is damaged or heavily contaminated, replace it; best to be safe.
• Apply grease to exposed thruster seal and shaft.
• If hub is removed, the tunnel gasket must be replaced.
• Inspect motor, ensure all leads are still tight.
• Check all bolts and nuts are to correct torque.
• Check the motor assembly is dry and that the compartment is water tight.
• Check and clean out thruster compartment.

Electric:

• Inspect electric motor, ensure all leads are still tight.
• Brush out carbon dust from top of electric motor, especially on aluminium boats. Recommend qualified electrician.

Hydraulic:

Refer to hydraulic system supplier for service requirements.

5.2 Changing drive pin 110TT, 140TT, 185TT

Diagram Description (Fig 5.2.1 - 5.2.3): Shows the steps for changing the drive pin: cutting the cable tie, punching out pin parts, and tapping in the new pin with a plastic cable tie.

Additional controller

Pressing the opposite button on a second control panel when the thruster is operating will cancel operation of the thruster. Operating the same direction button when still in operation on another control panel will have no effect.
