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: If installing an IP assembly, it has been tested to be fully ignition protected so that it can be installed in areas with possible
explosive gases in accordance with ISO 8846)
• The electromotor will generate some carbon dust so any storage compartments must be separated from the thruster to prevent nearby items
from becoming dusty/ dirty. (NB: IP version motors do not generate dust)
• Installing the electromotor in a small compartment must be ventilated to ensure cooling of the electromotor.
• If the height of the room you are installing the thruster is limited, it can be installed horizontally or at any angle in-between.
- If the electromotor is positioned more than 30º 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 for the hull integrity without checking with the boat builder
this can be done safely.
• The electromotor, its components, contacts/ plugs or other joints in the control cables must be mounted so they will remain dry at all times.
• We advise painting the gear house and propellers with antifouling. (NB: Do not paint the anodes, sealings or propeller shafts)
• Do not  nish the inside of the tunnel with a layer of gelcoat/ 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 electromotor at close range to easily  ammable objects as it will reach over 100°C before the temperature switch is activated.
• Do not store items close to the thruster motor as it can reach 100°C. Any loose items near the thruster motor can cause problems with electrical
wiring coming loose and short-circuiting.

Positioning of the tunnel / thruster
EN MC_0003
Aim to install the thruster as far forward as possible (Fig. 1)
Due to the leverage eff ect around the boats’ pivot point. The relative distance diff erence from the boat pivots’ point to the thruster will determine the
amount of real thrust for the boats, rotation.
Example :
A: 100kg thrust x 11m leverage = 1100kgm torque to rotate the boat
B: 100kg thrust x 10m leverage = 1000kgm torque to rotate the boat
In position A you will get 10% more thrust to turn the boat around.
Aim to install the thruster as deep as possible under the waterline (Fig. 2)
Two reasons:
1. So it does not suck air down from the surface which will reduce thrust performance and increase noise levels during operation.
2. To get as much water pressure as possible to receive maximum effi ciency from the thruster.
The centre of the tunnel should be a minimum of 1 x the tunnel diameter below the waterline. However the installer must make evaluations based
on thruster performance, boat type and operating conditions. For average preformance the thruster it is at least 1.25 x tunnel diameter () below the
waterline. For best performance, the distance should be 1.5 x tunnel diameter () below the waterline. (NB: The position of the tunnel should not
be a minimum of 1/4 of the diameter of the tunnel from the boat keel.)

Tunnel Length
EN
Optimal tunnel length
Correct tunnel lengths depend on many factors from the hull type, operation and environmental conditions.
Tunnels should avoid being longer than 6 x the tunnel diameter as this will reduce thruster performance. (NB: Installing tunnels at longer lengths or if
added support is required for the tunnel consult a naval architect.)
1. If the tunnel is too long, the friction inside will reduce the water speed and thereby the thrust.
2. 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.
Standard Use
Tunnel length must be long enough to ensure the propellers are not extruding the tunnel.
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.
High-Speed Boats
Tunnel lengths must be increased to protect the propeller from damage when crashing against the water surface during high-speed cruising. The
optimal tunnel length is 3 x tunnel diameter (NB: This can include the length of a spoiler)

Water Defl ection
EN MC_0003
A possible problem in sailboats 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 (Fig. 1).
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 (Fig. 4).
This problem can be solved in two diff erent ways, depending on what is possible or easier to perform.
1. 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 (Fig. 2).
2. 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. (Fig. 3).
(NB: As a rule, you should not see the back face of the tunnel when standing directly in front of the boat looking aft.)
(NB: Remember always round the tunnel ends as much as possible to get optimum thruster performance and minimum noise.)

Tunnel installation in sailboats
EN
Some sailboats have a racing hull which means they may 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 sailboats, 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 sailboat 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.

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 6mm hole horizontally at these marks (Fig. 1). (NB: it is critical that the
thruster tunnel installed is perpendicular to the boats’ centre line)
2. Bend a steel bar as shown with the “tip” bent back set to the tunnel radius. Ensure the length of the bar runs through both holes. Mark the circle for
the tunnel opening (outside diameter of the tunnel). Cut the hole with a jigsaw (Fig. 2).
3. Grind off the gel coat and polyester so that you are in 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 (Fig. 4). (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 and clean with acetone or similar where you are going to apply  breglass.
(NB: Do not cast/ fi breglass on 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. If you are rounding the tunnel ends to the perfect 10% radius you may need to make further layers inside to preserve the desired hull
thickness. (See next page)
(NB: Make sure that any gaps between the tunnel and the hull are completely fi lled with resin/ fi breglass. In areas where you can not access
to make normal layers of resin/ fi breglass, a resin/ fi breglass mixture must be used in that area.)

Tunnel ends
EN MC_0003
Rounded tunnel ends will maximise thrust and minimise noise.
For best preformance round the tunnel connection to the hull-side as much as possible. The optimum 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 fast. (Fig. 1&2).
- The turbulence/ cavitation will block the outer area of the tunnel and thereby reduces the eff ective tunnel diameter and thrust.
- The turbulence/ cavitation hits the propeller and will lessen the propellers performance and create excess noise.
2. 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 (Fig. 3&4).
- 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.)
(NB: It is essential to round the tunnel end as much as possible. If it is not possible to round edges an angled tunnel to hull connection can
also off er similar performance as a rounded connection.)

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 6mm hole horizontally at these marks (Fig. 1). (NB: it is critical that the
thruster tunnel installed is perpendicular to the boats’ centre line)
2. Bend a steel bar as shown with the “tip” bent back set to the tunnel radius. Ensure the length of the bar runs through both holes. Mark the circle for
the tunnel opening (outside diameter of the tunnel). Cut the hole with a jigsaw (Fig. 2).
3. Grind off the gel coat and polyester so that you are in 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 (Fig. 4). (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 and clean with acetone or similar where you are going to apply  breglass.
(NB: Do not cast/ fi breglass on 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. If you are rounding the tunnel ends to the perfect 10% radius you may need to make further layers inside to preserve the desired hull
thickness. (See next page)
(NB: Make sure that any gaps between the tunnel and the hull are completely fi lled with resin/ fi breglass. In areas where you can not access
to make normal layers of resin/ fi breglass, a resin/ fi breglass mixture must be used in that area.)

With tunnel installed and cast (Fig. 1) round the edges with a radius of 10% of the tunnel diameter (Fig. 1a) or make a slope with a length of 10-15%
of the tunnel diameter (Fig. 1b). If this is not possible, round the tunnel end as much as possible.
Follow the same method if making the de ector/ spoiler (Fig. 2).
We advise to additionally cast two layers on the outside of the tunnel/ hull in a 10cm area (Fig. 1c & 1d).
You must apply topcoat/ epoxy to areas outside where you have grounded/ moulded to make these areas 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.)
If you desire to have another colour on the tunnel, you do not need to apply topcoat or the several layers of primer that is necessary on the boats’ hull to
make it water-resistant. Sand it very lightly and apply one coat of primer to make the anti-fouling sit.
(NB: Avoid all casting where the motor-bracket is to be placed, as this will cause misfi t and possible failure to the gear house.)

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 electromotor must be handled with care. Do not lift it by internal connections/ main terminals or placed down on the driveshaft.
• With the boat on land, run the thruster for short bursts.
• While the thruster is in the air, ensure that the propellers have come to a complete stop before performing a directional change of the thruster, as it
might cause damage to the thruster.
• It is important to follow the guidelines in this manual. Failure can result in sever damage to the thruster.
DC Ignition Protected Thrusters:
• If there is a problem with your Ignition Protected stern thruster, please contact your dealer.
NEVER
Disassemble any part of the Ignition Protected stern thruster assembly. Tampering with the Ignition Protected stern thruster assembly or any attempt to
disassemble anything on this thruster assembly inside the boat can cause an explosion with severe consequences.
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.

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(s) as shown above for the thrust direction
to correspond with the control panel. If installing a twin propeller, place gear leg with the P-mark facing port and the S-mark facing
starboard.)
2. Use the gasket or template (recommended) to mark the centre of the holes and double check the measurements. One hole MUST be placed with
the boat centreline as its centre as shown above. (NB: All holes must be in-line with the tunnels’ centreline for correct installation, as the
clearance between the propeller and the tunnel is minimal.)
3. There must be no casting where the motor bracket is to be installed, as this will cause possible failure to the gear leg. The motor bracket must rest
steady on the tunnel. If the tunnel is not smooth, all bumps or uneven parts must be ground  at.
4. Drill the main-hole and then the screw-holes.
5. Place the gear leg in the tunnel (without the propeller) with the gasket inside the tunnel. Place the propeller(s) to ensure it is in the centre of the
tunnel and rotates freely with the same clearance from each blade to the tunnel wall. If propeller(s) rotate off centre, try to use the other or both
gaskets.
6. Remove the gear leg and propeller for  nal installation. Apply MS Polymer sealant or equal to both sides of the gasket, and then run the gear leg
shaft through the central hole in the tunnel. With the gasket install the gear leg and motor bracket gently together. Use suited sealant to ensure that
no leakages occur. (NB: See your sealant datasheet for the correct application process.)
7. Fasten the gear leg and the motor bracket with the bolts provided. Fasten to torque as shown above.

Motor Installation
EN
1. Insert drive pin then the coupling to the motor shaft.
2. Install the motor onto the motor bracket ensuring both the couplings and the drive shafts have locked together. (NB: Depending on your coupling
you may need to wiggle the motor into place. Ensure the connection couplings are engaging correctly. The motor can be placed in all
directions on the motor bracket. However, ensure the cable terminals are accessible for electrical installation later.)
3. Fasten the motor loosely to the motor bracket with the provided bolts. (NB: If you are installing the motor at an angle of more than 30º off
vertical, the motor will require separate/ additional support.)
4. Fasten the bolts holding the motor to the motor bracket with the above torque.
5. 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.)
6. Apply the gear leg and propeller with antifouling designed for propellers. Do not apply to the propeller drive shaft, the anodes or the end of the gear
leg facing the propellers.
Only in shallow installations in workboat and  shing boats we recommend protecting the propeller by installing a grid in the tunnel opening. (NB: Keep
the grid confi guration to a minimum to ensure water fl ow for the thruster is not signifi cantly aff ected. Be aware that any grid confi guration
will change the eff ectiveness of the thruster and circular profi le steel will decrease thrust signifi cantly.)
(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.)

The coupling is complete with the gear pin to the gearleg.
So, there's only a new pin on the engine.
The tracks on the coupling are 90 degrees above each other. So, it becomes a joint.
This will mean that we are getting rid of clipping and cutting sounds as we are having today, and not eating up the drive pin.
The engine also becomes galvanically separated at the same time.
The coupling is just to tap on the engine axel lightly until it stops.

Thruster Electrical Installation
EN
IMPORTANT
Check the following with the main switch 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 fl ange and the positive terminal on the motor
2. electro-motor fl ange and the battery negative terminal on the motor
If unsure contact skilled personnel.
1. Explanation of electrical table. see next page
- All power cable lengths are the total of + and - (to and from).
- Battery size is stated as minimum cold crank capacity, not Ah.
- Use slow fuse rated to hold stated Amp-Draw for min. 5 minutes.
* Cable size and main battery size when an extra bow battery with minimum the CCA mentioned as A is installed.
2. Use appropriate sized cables and batteries with a high cranking capacity to feed the thruster. The actual voltage at the motor while running the
thruster decides the motors output RPM and thrust. You can use larger cables for better results.
- Advised minimum cables and batteries sizes. See next page.
3. Install the main switch in the main positive lead that can take the load without noticeable voltage drop and that can be turned off independently
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.
- A circuit breaker can be used instead of the fuse and main power switch If the functionality is the same.
(NB: For Ignition Protected installations remember to use ignition protected fuses and switches if fi tted in areas that require this
feature.)
5. Cables must have adequate electrical and mechanical isolation against contact with anything but the lead terminal on the battery and  tted with
cable ends.
6. Fasten cables to the required torque. see next page

Thruster Electrical Installation
EN
IMPORTANT
Check the following with the main switch 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 fl ange and the positive terminal on the motor
2. electro-motor fl ange and the battery negative terminal on the motor
If unsure contact skilled personnel.
1. Explanation of electrical table. see next page
- All power cable lengths are the total of + and - (to and from).
- Battery size is stated as minimum cold crank capacity, not Ah.
- Use slow fuse rated to hold stated Amp-Draw for min. 5 minutes.
* Cable size and main battery size when an extra bow battery with minimum the CCA mentioned as A is installed.
2. Use appropriate sized cables and batteries with a high cranking capacity to feed the thruster. The actual voltage at the motor while running the
thruster decides the motors output RPM and thrust. You can use larger cables for better results.
- Advised minimum cables and batteries sizes. See next page.
3. Install the main switch in the main positive lead that can take the load without noticeable voltage drop and that can be turned off independently
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.
- A circuit breaker can be used instead of the fuse and main power switch If the functionality is the same.
(NB: For Ignition Protected installations remember to use ignition protected fuses and switches if fi tted in areas that require this
feature.)
5. Cables must have adequate electrical and mechanical isolation against contact with anything but the lead terminal on the battery and  tted with
cable ends.
6. Fasten cables to the required torque. see next page

Control Panel Cable Installation
EN
• All standard Sidepower control panels can be used in any combination as well as any two-way switching device. If an automatic main switch is
installed, a separate switch to control on/off is required.
• Many control panels can be installed using optional Y-connectors or T-connectors if installing an 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.)
• When using original Sidepower equipment it is entirely “plug & go” and no additional con guration setup is required.
• All controls must have spring load for automatic return to neutral position.
(NB: If the drive direction of the thruster is running opposite to the control panel, swap the blue and grey wire on the control wire or control
box solenoid.
Pin con guration of 4 pole AMP contact:
Pin1: BLACK = Ground
Pin2: BLUE = Engages thruster SB solenoid
Pin3: GREY = Engages thruster Port solenoid
Pin4: RED = Positive voltage for the control panel
