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 stiff ener/ 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  ammable 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 Installation Considerations and Precautions
EN
Before installation, it is important that the installer reads this guide to ensure necessary acquaintance with this product.
• The electro motor must be handled with care. Do not lift it by internal cable connections, main terminals or placed down on the drive shaft.
• The thruster power supply circuit must include the recommended sized fuse and a battery isolation switch.
• Never run the thruster out of water.
• It is important to follow the guidelines in this manual. Failure can result in severe damage to the thruster.
IMPORTANT
If installing S-link products DO NOT connect any other control equipment to the S-link controlled products except Side-Power original
S-link products or via a Side-Power supplied interface product made for interfacing with other controls. Any attempt to directly control or
at all connect into the S-link control system without the designated and approved interface will render all warranties and responsibilities
for the complete line of Side-Power products connected void and null. If you are interfacing by agreement with Sleipner and through a
designated Side-Power supplied interface, you are still required to also install at least one original Side-Power control panel to enable
effi cient troubleshooting if necessary. MC_0265

Thruster Specifi cations
EN
*) Max thrust is available until the motor winding temperature exceeds 130°C and the dynamic thrust limitation gradually decrease the thrust to continuous rated performance. **) Motor output @ 230/400V supply. Actual value may vary depending on supply voltage and thruster install. ***) Current draw values are max values set in the VFD parameter setup. ****) Listed generator load is the maximum load value at standard thruster setup. Note that this value is diff erent from the required generator capacity. Required generator capacity will wary depending on generator characteristics and other loads on the system and have to be selected in cooperation with generator supplier. Side-Power SAC thrusters are in standard version powered by standard Variable Frequency Drives. Low harmonic drives (THD <5%) can be supplied on request.

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 fl ex/
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  ow 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  at 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  tting of a tunnel.
Instead  t the tunnel halfway into the underneath section of the existing hull. Strengthen it with a de ector/ spoiler directing the water  ow 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  at bottomed barges to avoid extremely long tunnels and large oval tunnel openings in the hull.

Water Defl ection
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
“ at” area facing the  ow of water (1).
This problem can be solved in two diff erent 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  ow 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  ow on this area (2).
3. Making a de ector/ spoiler in front and underneath the tunnel can also reduce damage to the thruster and drag. The de ector/ spoiler will push the
water  ow out from the hull so water can pass by the back face of the tunnel. The shape and size of this de ector/ spoiler will depend on the hull
shape. The easiest way of making the de ector/ 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- ow 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 eff ective 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 off er 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  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 defl ector/ 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.

Supporting the thruster
EN
consult a naval architect if added support is required for the tunnel at its deepest point to the hull as suggested in (fi g. 1 & 2).
The motor must be mounted on separate bedding placed according to (fi g. 3 & 4). The bedding must be rigid and dimensioned to support the weight
and torque speci ed in the technical data of the product.
The bedding must be in the correct height so that the angle of the cardan shaft does not exceed +/- 1.5 degrees (fi g. 5).
The distance from the centerline (fi g. 6) of the tunnel to the top of the bedding for the speci c thruster/ motor combination is found as measurement G
on the technical data of the product. Ensure that the bedding is parallel to the centerline by checking the distance in both ends of the bedding (Fig.5)
Mounting holes in the bedding should be drilled according to measurements J on the technical data of the product for the speci c thruster/ motor combi-
nation.

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 stiff ener/ 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  ammable 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.
It is the installers responsibility
When installing Side-Power equipment to follow the outlined regulations/ classi cation rules (electrical/ mechanical) according to
international or special national regulations. Instructions in this guide cannot be guaranteed to comply with global electric/ mechanic
regulations/ classi cation rules.
To follow all health and safety laws in accordance with their local outlined regulations/ classi cation rules.
Before installation, it is important that the installer reads this guide to ensure necessary acquaintance with this product.
The recommendations made in this manual are guidelines ONLY, and Sleipner Motor AS (Side-Power) strongly recommend that
before installation, advice is obtained from a naval architect familiar with the particular vessel and regulations/ classi cations.
This manual is intended to support educated/ experienced staff and is therefore not suffi cient in all details for professional
installation. (NB: These instructions are only general instruction. If you are not skilled to do this work, please contact professional
installers for assistance.)
All electrical work must be done by a licensed professional.
Faulty installation of Sleipner products will render all warranty given by Sleipner Motor AS void. MC_0038

Thruster Installation Considerations and Precautions
EN
Before installation, it is important that the installer reads this guide to ensure necessary acquaintance with this product.
• The electro motor must be handled with care. Do not lift it by internal cable connections, main terminals or placed down on the drive shaft.
• The thruster power supply circuit must include the recommended sized fuse and a battery isolation switch.
• Never run the thruster out of water.
• It is important to follow the guidelines in this manual. Failure can result in severe damage to the thruster.
IMPORTANT
If installing S-link products DO NOT connect any other control equipment to the S-link controlled products except Side-Power original
S-link products or via a Side-Power supplied interface product made for interfacing with other controls. Any attempt to directly control or
at all connect into the S-link control system without the designated and approved interface will render all warranties and responsibilities
for the complete line of Side-Power products connected void and null. If you are interfacing by agreement with Sleipner and through a
designated Side-Power supplied interface, you are still required to also install at least one original Side-Power control panel to enable
effi cient troubleshooting if necessary. MC_0265

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.

Coupling Installation
EN
Parts must be aligned with precision to ensure the longevity and eff ectiveness of the coupling, consider the combination of axial, radial and angular
misalignment.
Centa has applied retention Inbus PlusAll glue to all bolts. (NB: The glue will harden within 4-5 hours at 20˚C.) Additional use of any
loctite or anaerobic adhesives will destroy the natural vulcanisation of the rubber. Do not use oil or grease on bolts except a small amount of grease at
the contact areas between bolt heads and rubber element bushings. Grease will avoid the twisting of the rubber element during bolt fastening.
1. Insert the  ange hub on AC motor shaft and gear leg shaft. (NB: Insert the Gear leg shaft fl ange hub against the limit stop/ shaft shoulder. )
Insert the AC motor shaft fl ange hub according to hub depth.)
2. Install the AC motor after you have lined up according to tolerances given in the above table.
3. Insert the drive shaft inside the rubber elements. Insert radial bolts into radial sections of the rubber elements, and fasten 2-3 threads only into the
drive shaft.
4. Install the pre-mounted rubber elements and shaft between the two  ange hubs. Insert the Axial bolts and fasten 2-3 threads only into the  ange
hubs.
5. First fasten radial bolts, then the axial bolts according to the table above. (NB: Ensure rubber elements are not twisted during fastening the
bolts.)
Fastening bolts by hand/ user judgment is not suffi cient as this will result in a  nal bolt torque too low for operation. A low bolt torque will allow the bolts
to loosen over time, destroying the shaft. A torque wrench must be used to fasten bolts to speci ed torque tension.
Maintenance and Safety Precaution:
The coupling is entirely maintenance free. Avoid contact with oil and similar substances since the natural rubber is not oil resistant. For a detailed
Universal Joint Shaft installation manual, contact your Side-Power dealer. Add protection to the Universal Joint Shaft according to relevant safety
regulations. (NB: A protection guard is not a part of Side-Power delivery)
MC_0027
!Please refer to the graphic for special considerations relating to your model !
IMPORTANT
Only use original bolts delivered with the Side-Power thruster. Also, avoid contact between the AC motor shaft and the coupling drive shaft.
