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 or use an oil tank to ensure the maximum oil temperature is 43 - 50 degrees Celsius.
• 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.
• It is required that a device is installed to ensure that the drive direction cannot be suddenly changed, as this can severely damage the gear house.
(NB: By adding an electronic time-lapse/delay safety on the electric control system or by using a valve that has this type of protection built
in will prevent this issue. *The required time delay is 1 second.)

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.
• We advise painting the gear house 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.
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 DO NOT connect any other control equipment directly to the S-Link™ bus except original Sleipner S-Link™ products.
In case of connecting 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

For retract thrusters
• Stern mounted retract thrusters must not be installed to conflict with the main boat propellers or its water trail. (NB: consult a naval architect for

Preparing a Sandwich Hull for Retract Systems MC_0067
Hull construction typical in many vessels is a composite layering method called a sandwich. To ensure the retract thruster is installed securely to these
hull types, additional hull structure reinforcement is required to strengthen the area around the Sleipner retract housing mould.
1. To achieve maximum strength and bonding in the area around the installation of the retract thruster remove the inner and core material to expose
the outer laminate. Remove enough area for a 100mm (minimum) clearance surrounding the retract thruster housing.
2. Reinforce the area with bonding to strengthen the hull for the operation of the retract thruster.
3. During the process of attaching the retract thruster housing build this area up to ensure enough strength of the hull.
(NB: Consult an experienced boat builder)

Bow
The thruster must be installed as far forward as possible. Allow for 100mm around the thruster for moulding the retract frame and the depth of the
retracted propeller is a minimum of:
(185mm for retract systems 80 to 100) (250mm for retract systems 130 to 210) (300mm for retract systems 250 to 300)
under the waterline. For bow installations, the thruster must be installed in the centre line of the keel.
(NB: Installing the thruster further forward will give less depth for the propeller but offer better leverage effect for turning.)
Stern
The thruster must be installed as far forward as possible. Allow for 100mm around the thruster for moulding the retract frame and the depth of the
retracted propeller is a minimum of:
(185mm for retract systems 80 to 100) (250mm for retract systems 130 to 210) (300mm for retract systems 250 to 300)
under the waterline. The thruster while retracted must not conflict with any other component of the vessel such as stern drives/ propellers, trim tabs
or rudders. Therefore stern installations do not require to be installed on the hulls keel centre line and can be installed off centre.
Installing the thruster below the waterline as outlined is important for two reasons:
1. So that it does not suck air down from the surface which will reduce performance and increase noise levels.
2. To get as much water pressure as possible to receive maximum efficiency from the thruster.
Always ensure enough space for the complete SR unit including motor, actuators, retract frame, future service and for installation moulding to the hull.
The thruster must always be installed so the hatch is opened towards the direction of travel.

Marking and Trimming of SRF Flange
1. Identify the location of the thruster considering space required for installation, operation and future maintenance.
2. Mark the keel centre line on the inside of the hull. Flip the SRF flange upside down and use the internal surface to mark the hull for cutting the
thruster hatch. (NB: Ensure the mould is centred.)
3. The SRF flange must sit so the two side rails run flush with the length of the hull. To do so the SRF flange tabs must be trimmed down to match the
hull pro le curvature. (NB: Consult a naval architect for methods to transfer the hull profi le to the SRF flange. DO NOT cut the SRF flange length
edge.)
4. Cut the hatch door. The hatch opening must be cut at an angle of 45º on three sides and 30º on the bow face. This allows any water forces hitting
the hatch while closed to be absorbed by the hull, not the thruster. (NB: Use a suitable cutting tool able to be set to the desired angle. If cutting
from outside the hull drill 4 holes from the internal marked corners to see the required profi le from the outside.)

Installation Pre-check
Temporarily set up the complete installation to ensure no conflicts during the  nal operation of the thruster.
1. Use polyester or resin in the 4 corners of the lower retract mould and set it over the hatch. Attach the upper retract mould to the lower retract
mould with 4 corner screws to hold them securely in place. 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 12 or 24 DC cables (refer to the label on actuators for correct voltage) to the 6 mm cables on the terminals on the controller.
Set switch no. 4 on the DIP-switch marked “SETTINGS” to ON. Remove the wooden safety part located above the tunnel.
3. Press “DOWN” to extend the retract mechanism and check the hatch opens fully without touching the hull. If the hatch is obstructed by the hull,
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 propeller mechanism. 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.
MC_0068
!Please refer to the graphic for special considerations relating to your model !
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.

SRF Flange Installation
1. Surfaces to be moulded/ bonded must be ground to remove coating and material to achieve suf cient adhesion.
2. Apply Epoxy  ller or equivalent on bottom edges of SRF flange or on the hull for bonding between connection surfaces. Ensure the  ller is
compatible with hull materials.
3. Place the SRF flange into position ensuring the correct orientation. Fill gaps between SRF and hull with Epoxy  ller or equivalent. Grind and
smooth the surfaces after curing time.
4. Apply layers of  bre glass and ensure that resin is compatible with hull materials.
5. After curing time, smooth all moulded surfaces and apply coating. Apply putty before coating if necessary.
After moulding in SRF flange is completed, the upper thruster case is ready to be installed.
General Moulding process
Start the laminating with a strong attachment point in each corner between the hull and the outside of the lower unit. Use epoxy and  breglass cutting
or similar, which laminating material is the actual boat builders responsibility. Cover the upper part if grinding is necessary. After moulding material
have cured, run the retract mechanism down, disassemble the hatch and remove the upper part from the unit.
Laminate the inside and outside of the SRF flange solid to the hull. Use appropriate  breglass cloth (which laminating material is the actual
boat builders responsibility). Before grinding of hull and SRF flange, precautions must be taken against grinding dust inside the boat. Grind deepest
where the hull and SRF flange meets.

1. Fit custom made pin bolts to the tunnel rings. The ends of the bolts must be sharp to create marks in the hatch. The pin bolts must be in
correct height so the hatch will  t in its inner position.
2. Place hatch in its inner position, then press or tap with a hammer to create punch marks inside of the hatch.
3. Drill 4 marked holes and countersink the outer hull side. (NB: drill holes 90 to the hatch surface.)
4. Temporary  t the hatch to the tunnel rings. Ensure the bolts do NOT conflict with the propeller tunnel. (NB: Bolts can be cut, depending on hull
thickness.)
5. Fill the gap between hatch and hull edges.
6. Apply a layer of aluminium or duct tape on hatch opening edges on the hull. Apply Epoxy  ller or equivalent to hatch edges to create a perfect
seal.
7. Operate the thruster to “IN” position. Smooth out the  ller and add more if needed. After curing time, grind and smooth the surface.
8. Unscrew and remove hatch to smooth off excessive material before coating the hatch.
9. Apply  ller on to tunnel rings contact surface, so the hatch will be secured properly. Now re-install hatch in its correct position. Tighten bolts so
hatch will  t properly.
10. Apply coating inside and outside of hatch opening on hull.

Oil Tank Installation
1. Install the oil tank 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 tank oil tank to the feed nipple on the motor bracket. Fasten the two 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 tank with the same gear oil used in the gear leg. The oil tank works as an indicator to ensure there is oil 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.)

S-Link System Description
S-Link is a CAN-based control system used for communication between Sleipner products installed on a vessel. The system uses BACKBONE Cables
as a common power and communication bus with separate SPUR Cables to each connected unit. Units with low power consumption are powered
directly from the S-Link bus therefore one power cable must be connected to the BACKBONE Cable through a T-Connector.
Main advantages of S-Link system:
- Compact and waterproof plugs.
- BACKBONE and SPUR Cables have different colour coding and keying to ensure correct and easy installation. BACKBONE Cables have blue
connectors and SPUR Cables have green connectors.
- Different cable lengths and BACKBONE Extenders makes the system scalable and flexible to install.
Installation of S-Link cables:
Select appropriate cables to keep the length of BACKBONE- and SPUR Cables to a minimum. In case of planned installation with total BACKBONE
Cable length exceeding 100 meters please consult your local distributor. The S-Link cables should be installed to ensure sharp bend radius’s is
avoided. Locking mechanism on connectors must be fully closed. To ensure long lifetime, cables, T-Connectors and Extenders should not be
located so that they are permanently immersed in water or other fluids. It is also recommended to install cables such that water and condensation do
not run along the cables and into the connectors.
The POWER Cable should ideally be connected around the middle of the BACKBONE Cable to ensure an equal voltage drop at each end of the
BACKBONE Cable. The yellow and black wire in the POWER Cable shall be connected to GND and the red wire connected to +12VDC or +24VDC.
To reduce the risk of interference, avoid routing the S-Link cables close to equipment such as radio transmitters, antennas or high voltage cables. The
backbone must be terminated at each end with the END Terminator.
SPUR cables can be left unterminated to prepare for the installation of future additional equipment. In such cases, ensure to protect open connectors
from water and moisture to avoid corrosion in the connectors.
