For thruster systems
• Do not install the thruster in a position where you need to cut a stiffener/ stringer/ support that may jeopardise the hull integrity without checking
with the boat builder this can be done safely.
• Paint the gear leg and propellers with anti-fouling. (NB: Do not paint the anodes, sealing, rubber fi ttings or propeller shafts)
• There is only room for a thin coat of primer and two layers of anti-fouling between the tunnel and the props.
• Never run the thruster out of water without load. Operated at no load, the motor will reach extremely high speed, damaging the system.
Failure to follow the considerations and precautions can cause serious injury, damage and will render all
warranties given by Sleipner Motor as VOID. MC_0411
When installing an S-Link™ system connect ONLY original Sleipner S-Link™ products or other authorized control equipment directly to the S-Link™ bus.
Connecting non-authorized third-party equipment, it must always be connected through a Sleipner supplied interface product.
Any attempt to directly control or connect into the S-Link™ control system without a designated and approved interface will render all warranties and
responsibilities of all of the connected Sleipner products. If you are interfacing the S-Link™ bus by agreement with Sleipner through a designated
Sleipner supplied interface, you are still required to install at least one original Sleipner control panel to enable efcient troubleshooting if necessary.
MC_0105
MC_0474
For retract thrusters
• Stern mounted retract thrusters must not be installed to conflict with propulsion propellers or its water trail. (NB: consult a naval architect for
an exact position.)
• Paint inside the retract housing with anti-fouling. (NB: Do not paint the drive shaft.)

If an original Sleipner hydraulic system is NOT installed, please ensure the following:
• Install an oil  lter to keep the oil clean.
• Fit an oil cooler to ensure that the maximum oil temperature is below 75°C. Recommended operation temperature of hydraulic oil is 40-60°C.
• Hydraulic thrusters are supplied with hydraulic motors only.
• The installed hydraulic system is the responsibility of the  tter/ installer and must be within the limitations outlined in this manual to ensure no
damage is caused to the thruster.
• The hydraulic valve must have flow and pressure limits that are either set within or can be adjusted to the limits of the thrusters capability.
• We strongly advise that a shock valve is  tted and set to 10% - 15% above the chosen maximum pressure set in the valve. This will prevent the
system from being damaged if the propellers are blocked for any reason.
• Install a device to ensure the drive direction cannot be suddenly changed, as this can severely damage the gear leg. (NB: Use a electric control
system or a valve that ensures minimum 1 second delay when changing drive direction.)

Preparing a Sandwich Hull for Retract Systems MC_0067
For vessels with sandwich hull construction, additional reinforcement of the area around the SRF flange is required.
1. To achieve maximum strength and bonding in the area around the installation of the SRF flange remove the inner laminate and core material to
expose the outer laminate. Remove enough area for a 100mm (minimum) clearance surrounding the SRF flange.
2. Reinforce the area by applying several bonding layers to strengthen the hull for the operation of the retract thruster.

Retract Thruster
Ensure enough space for the complete retract unit including room for installation of SRF flange and for future service. Allow 100 mm of clear space
around the thruster for moulding of the SRF flange. Ensure that when the thruster is deployed the depth of the propeller exceeds the minimum tunnel
depth defined in below table.
Installing the thruster below the waterline as outlined is important for two reasons:
1. Avoid drawing air from the surface which will reduce performance and increase noise levels.
2. To get as much water pressure as possible to achieve maximum thrust.

Stern installation
To avoid conflict between the thruster and propulsion propellers, trim tabs or rudders the stern installation can be offset from the keel center line.
Bow installation
The thruster must be installed in the center line of the keel and as far forward as possible while following the minimum propeller water depth
requirement. The thruster must always be installed so the hatch is opened towards the bow.

2. Flip the SRF flange upside down and position it at the identi ed installation location. Use the internal edge to mark the hull for cutting the thruster
hatch.
3. The SRF flange must sit so the two side rails run flush with the hull. To do so the SRF flange must be trimmed down to match the hull pro le
curvature. (NB: For guidance or methods to transfer the hull profi le to the SRF flange for cutting, consult a naval architect. DO NOT cut the SRF
flange length edge.)

Marking and Trimming of SRF Flange
4. Prepare for cutting the hatch door. Drill 4 holes at a 45º angle towards the starboard and port side. (NB: Cutting the hatch from outside the hull
the 4 drill hole from the internal marked corners will aid in determining the hatch profi le from the outside.)
5. The hatch opening must be cut at an angle of 45º on three sides and 30º on the side facing the bow. This ensures that forces from water hitting
the closed hatch is absorbed by the surrounding hull. (NB: Use a suitable cutting tool able to be set to the desired angle.)

Installation Pre-check
Temporarily set up the complete installation to ensure no conflicts during the  nal operation of the thruster.
1. Use epoxy  ller in the 4 corners of the SRF flange and set it over the hatch. Attach the retract housing retract flange with 4 corner screws to hold.
Use polyester or resin to attach the hull hatch to the retract unit. (NB: Ensure correct orientation for the thruster to open the hatch facing the
direction of water flow. Remember attachment is for temporary checking of thruster operation only.)
2. Temporarily connect DC cables (NB: Refer to the label on actuators for correct voltage) to the cables on the terminals on the controller. Set switch
no. 4 on the DIP-switch marked “SETTINGS” to ON. Deploy thruster and remove the red distance part located above the tunnel.
3. Press “DOWN” to extend the tunnel and check the hatch opens fully without touching the hull. If the hatch is obstructed by the hull in the front,
lift the aft end of the SRF flange maintaining the reference height in front - until the hatch clears the hull when opened.
4. Press “UP” to retract the tunnel. Ensure when the hatch is closed extra pressure is on the contact surface between the hatch and the hull only. If
the hatch is not closing with pressure on the contact surfaces the entire SRF flange must be raised.
After all, pre-checks are completed the retract system can be installed.
MC_0068
IMPORTANT
The hatch contact edges and the hull contact edges MUST work as the mechanical end stop. During cruising, slamming forces from the water must
be absorbed by these areas, not the thruster.
Accidental activation of the retract mechanism can cause serious injury due to the high-pressure
force used for moving the hatch. IF operating the hatch during any work/ maintenance around or
inside the retract hatch, USE CAUTION.

Required Modifi cations After Pre-check
To increase the space between the hatch and the hull the entire SRF flange and motor must be raised at the stern end.
1. With the hatch in the open position raise the stern end of the SRF flange and motor until the appropriate clearance is achieved. (NB: continue to
raise the stern height until this is obtained.)
2. Use a wedge to keep the thruster stable.
3. Open and close the hatch to ensure:
- Clearance between the hull and hatch when the thruster is open
- Hatch closes flush with the hull with full contact between hatch and hull.
4. Record the height and keep the wedges in place and secure the position of the SRF flange with epoxy  ller in the corners.

Motor to House Installation
1. Install the motor onto the motor bracket ensuring both the couplings and the drive shafts have locked together. The motor must be installed
with the solenoid facing the control box. (NB: depending on your coupling you may need to wiggle the motor into place. Ensure the connection
couplings are engaging correctly. Ensure the motor cable terminals are accessible for electrical installation later.)
2. Fasten the bolts holding the motor to the motor bracket with the above torque.
3. Check the drive shafts engage by rotating the propeller. It is required the propeller can rotate via hand power. (NB: Rotating the propellers can be
hard because of the gear reduction and the motor.)
4. Apply the gear leg and propeller with anti-fouling designed for propellers. Do not apply to the propeller drive shaft, the anodes or the end of the
gear leg facing the propellers.
(NB: The motor must be covered to avoid dust from fabrication/ maintenance operation entering the motor or the solenoids. After fabrication
maintenance operations have ceased the cover must be removed before operating the thruster.)

Oil Tank Installation
1. Install the oil container above the waterline by at least 20% of the distance from the waterline to the centre of the tunnel. This ensures enough
overpressure for the oil in the gear leg.
2. Install the oil tube from the oil container to the feed nipple on the motor bracket. Fasten both the tube clamp screws. (NB: Ensure the oil tube has
no loops and forms an airlock to stop the oil flow. Ensure the oil tube angle is suffi cient to allow oil to flow freely into the gear leg.)
3. Fill the oil container with the same gear oil used in the gear leg. The oil container works as an indicator to ensure oil is in the gear leg at all times.
(NB: Fill and drain the gear leg simultaneously while replacing the oil to ensure the system is never empty.)
