For electric motor thrusters
• The thruster must NOT be installed in compartments that require ignition proof electric equipment. If necessary, make a separate compartment.
(NB: Ignition Protected systems are tested to be installed in areas with possible explosive gases in accordance with ISO 8846)
• When installing the thruster electric motor in small compartments, ensure the compartment is well ventilated to allow for cooling of the electro
motor.
• If the height of the room you are installing the thruster is limited, the thruster can be installed horizontally or at any angle in-between.
- If the electro motor is positioned more than 30 degrees off vertical, it must be supported separately.
- Beware of keeping installation within advised measurements. No part of the propeller or gear house must be outside the tunnel.
• The electro motor, components and cables must be mounted so they remain dry at all times.
• We advise painting the gear house and propellers with anti-fouling. (NB: Do not paint the anodes, sealing, rubber fi ttings or propeller shafts)
• Do not fi nish the inside of the tunnel with a layer of gel-coat/ topcoat or similar. There is only room for a thin coat of primer and two layers of anti-
fouling between the tunnel and the props.
• Don’t install the electric motor close to easily flammable objects or equipment as it will reach over 100°C before the temperature switch is
activated.
• Do not store items close to the thruster motor. Any loose items near the thruster motor is a potential fi re hazard and can cause undesired short-
circuiting.
• Do not lift it by internal cable connections, main terminals.
• The thruster power supply circuit must include the recommended sized fuse and a battery isolation switch.
MC_0425
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.
• The electric/ hydraulic motor must be handled with care. Do not place down the thruster on the motor drive shaft or gear leg if attached.

Positioning of the tunnel / thruster MC_0003
Aim to install the thruster as far forward as possible (1)
Due to the leverage effect around the boats’ pivot point. The distance difference from the boat pivots’ point to the thruster will determine the amount
of real rotation power for the boat.
Aim to install the thruster as deep as possible under the waterline (2)
Deeper installations prevent air from being sucked into the tunnel from the surface, resulting in reduced thrust performance and increase noise levels
during operation. Deeper installations increase water pressure for maximum effi ciency from the thruster.
The centre of the tunnel should be a minimum of 1 x the tunnel diameter below the waterline. The installer must make evaluations based on thruster
performance, boat type and operating conditions. As a general recommendation, the position of the tunnel should not be a minimum of 1/4 of the
diameter of the tunnel from the boat keel. (NB: This can be overlooked depending on the installation methods defi ned in this manual.)

1. Do not allow the variable length of the tunnel walls to vary in length excessively.
EG. The top tunnel wall is x 4 longer than the bottom wall.
2. If the tunnel is too long, the friction inside will reduce the water speed and thereby the thrust.
3. If the tunnel is too short (typically only in the bottom section of the tunnel) cavitation problems can occur as water flow will not be able to
“straighten” itself before reaching the propeller. This cavitation will reduce performance and increase noise during operation.
Thruster within the tunnel
It is important the propellers and the lower unit/ gear leg must be entirely inside the thruster tunnel. Propellers that protrude from the tunnel will not

4. Standard Use

5. Flat Bottom Hull
Tunnel lengths must be longer than the standard measurement outlined within the manual to ensure a circular vacuum is not created between the

Tunnel installation in Sailboats
Some sail boats have a flat bottom and shallow draft in the bow section. This can make installing the thruster as far forward from the boats main pivot
point diffi cult. (Fig. 1).
However, it is possible to install a tunnel thruster in most sail boats, even when the hull does not directly support the fi tting of a tunnel.
Instead fi t the tunnel halfway into the underneath section of the existing hull. Strengthen it with a deflector/ spoiler directing the water flow around
the tunnel. This will allow installation of the thruster in the proper position on the boat, maintaining the reliability and space advantages of the tunnel
thruster.
This installation is being used by some of the world’s largest sail boat builders and has proven to give little to no speed loss during normal cruising.
This can also be an installation method for flat bottomed barges to avoid extremely long tunnels and large oval tunnel openings in the hull.

Water Deflection MC_0003
1. A possible problem in sail boats or fast powerboats is that a non-rounded surface can generate drag from the back face of the tunnel, as it creates
a “flat” area facing the flow of water.
This problem can be solved in two different ways, depending on what is possible or easier to perform.
2. The best solution which generally reduces the most drag is to make a recess in the hull at the back of the tunnel. As the back face is removed
water can flow freely past the tunnel entry. The depth and shape of this recess will depend on the boat and the angle facing up/ down aft of the
tunnel insert. Normally it is angled slightly down because of the water flow on this area.
3. Making a deflector/ spoiler in front and underneath the tunnel can also reduce damage to the thruster and drag. The deflector/ spoiler will push
the water flow out from the hull so water can pass by the back face of the tunnel. The shape and size of this deflector/ spoiler will depend on the
hull shape. The easiest way of making the deflector/ spoiler is to retain a part of the lower forward area of the tunnel while installing the tube. Use
this area as support to mould a soft curve/spoiler shape from the hull.
4. The thruster propeller can spin (passively) producing noise while sailing or cruising as water is forced through the tunnel. Water-flow directed
through the tunnel at high speeds, during turning or as the boat bumps waves while underway can also damage the thruster.
(NB: As a rule, you should not see the back face of the tunnel when standing directly in front of the boat looking aft.)

Tunnel Ends MC_0003
Rounded tunnel ends will maximise thrust and minimise noise and cavitation.
For best performance round the tunnel connection to the hull-side as much as possible. The minimum rounding has a radius of 10% of the diameter of
the tunnel.
Signifi cant advantages of a rounded tunnel over a sharp tunnel to hull connections are:
1. A rounded tunnel end will prevent the creation of turbulence/ cavitation created from a sharp tunnel end when water passes by the tunnel.
- The turbulence/ cavitation will block the outer area of the tunnel and thereby reduces the effective tunnel diameter and thrust.
- Turbulence/ cavitation on the propeller will lessen the thrusters performance and create excess noise.
2. For steel/ aluminium hulls angled tunnel ends also offer similar performance as a rounded connection.
3. A rounded tunnel end makes the thruster draw water from along the hull-side, creating a vacuum that will suck the boat sideways and thereby give
additional thrust.
- With a sharp tunnel end, the thruster will be unable to take water from along the hull-side, and you will not gain the desired vacuum and
additional thrust. This “free” extra thrust in optimal installations be 30 - 40% of the total thrust.
(NB: A Side-power thruster propeller does not produce cavitation at working speed. Therefore, any cavitation and cavitation noise in the tunnel will
be caused during improper tunnel installation.)

Tunnel Installation
1. Find the position in the boat considering the information earlier in this manual and the applicable measurements for the thruster model you are
installing. Mark the centre of the tunnel on both sides of the hull. Drill a hole horizontally at these marks.
2. Mark the circle for the tunnel opening (outside diameter of the tunnel) and cut the hole.
3. Grind off the gel coat to the “real fi breglass” area 12cm around the hole on both inside and outside the hull to cast the tunnel to the hull (Fig. 3).
4. Insert the tunnel and mark its shape to fi t the hull. (NB: if you are installing with a deflector/ spoiler, leave a part of the tunnel in the front and
underside of the tunnel that will cover the back face.)
5. Cut the tunnel ends to the desired shape and lightly sand its surface. Clean the area with acetone or similar where you are going to apply
fi breglass. (NB: Do not cast or add fi breglass to the area were the thruster will be placed.)
6. Cast the tunnel to the inside of the hull, use at least eight layers of 300g fi breglass and resin, preferably alternating mat and rowing types of
fi breglass. To round the tunnel ends to a 10% radius make further layers inside to preserve the desired hull thickness.
(NB: Ensure gaps between the tunnel and the hull are completely fi lled with resin/ fi breglass. In areas where you can not access to make
layers of resin/ fi breglass, a resin/ fi breglass mixture must be used in that area.)

IMPORTANT
We recommend that a professional does the fi breglass, steel or aluminium fi tting of the tunnel. These instructions are only general
instructions and do not explain in any way the details of fi breglass work. Problems caused by faulty installation of the tunnel, are the
installers full responsibility.

Tunnel Installation
1. Find the position in the boat considering the information earlier in this manual and the applicable measurements for the thruster model you are
installing. Mark the centre of the tunnel on both sides of the hull. Drill a hole horizontally at these marks.
2. Mark the circle for the tunnel opening (outside diameter of the tunnel) and cut the hole.
3. Grind off the gel coat to the “real fi breglass” area 12cm around the hole on both inside and outside the hull to cast the tunnel to the hull (Fig. 3).
4. Insert the tunnel and mark its shape to fi t the hull. (NB: if you are installing with a deflector/ spoiler, leave a part of the tunnel in the front and
underside of the tunnel that will cover the back face.)
5. Cut the tunnel ends to the desired shape and lightly sand its surface. Clean the area with acetone or similar where you are going to apply
fi breglass. (NB: Do not cast or add fi breglass to the area were the thruster will be placed.)
6. Cast the tunnel to the inside of the hull, use at least eight layers of 300g fi breglass and resin, preferably alternating mat and rowing types of
fi breglass. To round the tunnel ends to a 10% radius make further layers inside to preserve the desired hull thickness.

IMPORTANT
Avoid all casting where the motor-bracket is to be placed, as this will cause misfi t and possible failure to the gear house.
Tunnel Installation
With tunnel installed and cast.
1. Round the edges with a radius of 10% of the tunnel diameter.
2. For steel/ aluminium hulls make a slope with a length of 10-15% of the tunnel diameter.
(NB: If this is not possible, round the tunnel end as much as possible.)
3. Additionally cast two layers on the outside of the tunnel/ hull in a 10cm area
4. Follow the same method if making the deflector/ spoiler.
You must apply gel coat to areas you have grounded/ moulded to make waterproof. These areas allow water access to the hull which is typically not
waterproof without these applications outside. (NB: All original Side-Power tunnels are fully waterproof when delivered except in the areas where
you have cut and bonded it to the hull.)

Gear Leg & Motor Bracket Installation
!Please refer to the graphic for special considerations relating to your model !
1. Mark the tunnel centreline and the boat’s centreline. (NB: Install the gear leg and propeller as shown above for the thrust direction to correspond
with the control panel. Position gear leg with the P-mark facing port and the S-mark facing starboard.)
2. Use the gasket or template (recommended) to mark the hole centres and double-check the measurements. The centre hole MUST be placed
using the boat centreline as shown above. (NB: All holes must be in-line with the tunnels’ centreline for correct installation, clearance between
the propeller and the tunnel is minimal.)
3. Smooth the surface of the tunnel. A rough surface will cause possible failure/movement of the gear leg. The motor bracket must rest steadily on
the tunnel.
4. Drill the main centre hole followed by the two screw-holes.
5. Place the gear leg (without the propeller) with the gasket on inside the tunnel. Place the propeller on the gear leg to ensure it is centred and
rotates freely with the same clearance from each blade to the tunnel wall. Place top motor bracket to measure the drive shaft has come through
the motor bracket at the correct height. Remove the gear leg and propeller for fi nal installation.
6. Apply appropriate sealant to both sides of the gasket and place on the gear leg. Place the gear leg in the tunnel (without the propeller).
7. Install the top motor bracket and gear leg gently together. Use appropriate sealant to ensure that no leakages occur. (NB: See your sealant data
sheet for the correct application process.)
8. Fasten the gear leg and the motor bracket with the bolts provided. Fasten to torque as shown above.

Motor Installation
1. Install the motor onto the motor bracket ensuring the couplings are engaged together correctly (top and bottom). (NB: The motor can be placed
in all directions on the motor bracket. However, ensure the cable terminals are accessible for electrical installation later.)
2. If you are installing the motor at an angle of more than 30 degrees off vertical, the motor will require separate/ additional support. (NB: Do not
position supports on the motors top cap.)
3. Fasten the bolts holding the motor to the motor bracket with the above torque.
4. Check the drive shafts are engaged by rotating the propeller. (NB: Rotating the propellers can be hard due to the gear reduction and the motor,
however the propeller must be able to rotate via hand power.)

WARNING
Check the following with the main switch is set to off. After all electrical connections have been completed check with an ohm meter that
there is no electrical connection between
1. electro-motor flange and the positive terminal on the motor
2. electro-motor flange and the battery negative terminal on the motor
(If unsure contact skilled personnel.)
1. Information of electrical table.
- All power cable lengths represent the total length of the combined (+) and (-) cables.
- Battery capacity is stated as minimum cold crank capacity, (CCA).
- Use slow blow rated fuses to hold stated Amp-Draw for min. 5 minutes.
- Consider the AMP hours (Ah) for your specifi c duty cycle.
2. Use appropriate sized cables and batteries with high cranking capacity to feed the thruster. The actual voltage at the motor while running the
thruster decides the motors output RPM and thrust. Use larger cables and stronger batteries for better results.
- See electrical specifi cations for advised minimum cables and batteries (CCA).
3. Connect the battery supply to the control unit (PPC).
- Install a main manual/ automatic switch from the positive lead terminal on the battery PPC unit). The main switch must be accessible to turn
off the thruster independently from the rest of the electrical operation of the vessel when not on-board or in emergencies. (NB: It is advised
to install a fuse on the positive cable for protection against short-circuiting of the main cables. The fuse should ensure no voltage
decrease, slow-blow and sized to take the amperage draw for at least 5 minutes.)
- A circuit breaker can be used instead of the fuse and main power switch If the functionality is the same.
4. Cable lugs must have adequate electrical and mechanical isolation and fi tted with cable lug covers.
5. Fasten cables to the required torque.
(NB: For Ignition Protected installations remember to use ignition protected fuses and switches if fi tted in areas that require this feature.
Ensure to follow your national regulations)

- Install a main manual/ automatic switch from the positive lead terminal on the battery PPC unit). The main switch must be accessible to turn
off the thruster independently from the rest of the electrical operation of the vessel when not on-board or in emergencies. (NB: It is advised
to install a fuse on the positive cable for protection against short-circuiting of the main cables. The fuse should ensure no voltage
decrease, slow-blow and sized to take the amperage draw for at least 5 minutes.)
- A circuit breaker can be used instead of the fuse and main power switch If the functionality is the same.
4. Cable lugs must have adequate electrical and mechanical isolation and fi tted with cable lug covers.
5. Fasten cables to the required torque.
(NB: For Ignition Protected installations remember to use ignition protected fuses and switches if fi tted in areas that require this feature.
Ensure to follow your national regulations)

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.
