Bow Installation Considerations and Precautions
EN
• 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)
• The electro motor will generate some carbon dust so any storage compartments must be separated from the thruster to prevent nearby items
becoming dusty/ dirty. (NB: IP version motors generate dust but are enclosed.)
• When installing the thruster electro 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.
• 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.
• 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  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 electro 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  re hazard and can cause undesired short-
circuiting.

Positioning of the tunnel / thruster
EN 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 ef 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.)

Tunnel Length
EN
Optimal tunnel length
Achieving the correct tunnel length depends on many factors from the hull type, operation and environmental conditions.
Tunnels should avoid being longer than 4 x the tunnel diameter as this will reduce thruster performance. (NB: Installing long length tunnels can flex/
bend over time and may require additional support. Consult with a naval architect.)
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
perform as intended.
4. Standard Use
Tunnel length must be long enough to ensure the propellers are not extruding the tunnel.
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
thruster and the bottom of the boat.
6. High-Speed Boats
Tunnel lengths must be increased to protect the propeller from damage when crashing against the water surface during high-speed cruising. (NB:
This can include the length of a spoiler)

Tunnel installation in sailboats
EN
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 dif 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  tting of a tunnel.
Instead  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
EN 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 (1).
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 (2).
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. (3).
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 (4).
(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
EN 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.
Signi 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
EN
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  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  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
 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  breglass and resin, preferably alternating mat and rowing types of
 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.)
MC_0003
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 Ends
EN 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.
Signi 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.)

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 !
EN
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  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.

Bow Installation Considerations and Precautions
EN
• 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)
• The electro motor will generate some carbon dust so any storage compartments must be separated from the thruster to prevent nearby items
becoming dusty/ dirty. (NB: IP version motors generate dust but are enclosed.)
• When installing the thruster electro 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.
• 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.
• 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  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 electro 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  re hazard and can cause undesired short-
circuiting.

Thruster Electrical Installation
EN
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. see next page
- 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 speci 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 speci cations for advised minimum cables and batteries (CCA).
3. Install the main switch as close to the battery as possible and ensure the main positive lead can take loads without noticeable voltage drop.
- Ensure the main switch (battery isolator) can be turned off independently and manually when not on board or in emergencies.
- Ensure it is easily accessible and update instructions that this should be turned off like the boat’s other main switches.
It is advised to install a fuse in the positive lead for protection against short-circuiting.
- Ensure a slow type and appropriately sized to take the amperage draw for at least 5 minutes.
(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)
5. Cable lugs must have adequate electrical and mechanical isolation and  tted with cable lug covers.
6. Fasten cables to the required torque.

Thruster Electrical Installation
EN
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. see next page
- 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 speci 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 speci cations for advised minimum cables and batteries (CCA).
3. Install the main switch as close to the battery as possible and ensure the main positive lead can take loads without noticeable voltage drop.
- Ensure the main switch (battery isolator) can be turned off independently and manually when not on board or in emergencies.
- Ensure it is easily accessible and update instructions that this should be turned off like the boat’s other main switches.
It is advised to install a fuse in the positive lead for protection against short-circuiting.
- Ensure a slow type and appropriately sized to take the amperage draw for at least 5 minutes.
(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)
5. Cable lugs must have adequate electrical and mechanical isolation and  tted with cable lug covers.
6. Fasten cables to the required torque.

Control Panel Cable Installation
EN
• All Sleipner control panels can be used in any combination.
• All control panels can be installed using:
• Y-connectors - for standard on/off
• T-connectors - for S-link proportional power system.
(NB: If two or more control panels are operated at the same time in opposite directions, the electronic control box will stop the thruster until
it receives a single signal or thrust in one direction.)
• Sleipner on/off equipment it is entirely “plug & play” and require no additional con guration setup.
See the Control panel manual for more information.

With Manual Main Switch:
IMPORTANT
Check the following with the main switch in the off position
After all electrical connections have been completed check with an ohm meter that there is
no electrical connection between electro motor body and positive terminal on the motor and
between the electro motor body and the negative (A1) terminal on the motor. If you feel
unsure about how to perform this check, contact skilled personnel for guidance
Common negative MUST be wired when using control panel 8940 and 8909C if separate
battery banks are installed. (Bow and Stern thrusters combined)
