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.
MC_0267
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. If there is a problem with your
Ignition Protected stern thruster, please contact your dealer.
MC_0071
Installation Considerations and Precautions
EN
• Do not install the thruster in a position where you need to cut a stiffener/ stringer/ support for the hull integrity without checking with the boat
builder this can be done safely.
• Contacts/ plugs or other joints in the control 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 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 propellers.
• Keep installation within advised measurements. The entire surface is hard coated seawater resistant aluminium. Do not damage/penetrate the coat.
• The external stern thruster assembly and controller unit are ignition protected and can be installed in areas with the chance of explosive gases in
accordance to ISO 8846 and ABYC c1500. (Certi cation pending)
• Ensure that the external stern thruster assembly does not disturb the water flow under the hull. At higher speeds, if the thruster is installed to
low it can cause damage to the thruster and/ or add additional drag and unwanted water splashing.
• The recommended minimum tunnel depth from the water surface is 140mm (5,51‘) to the centre of tunnel diameter. Place the Thruster as deep as
possible for better performance and reduced noise.
• When installing the thruster ensure it does not foul existing equipment inside the boat like motor bedding etc.
• If able ensure that stern-drives/ trim-tabs do not interfere with the water flow from the thruster as this can reduce the thrust effectiveness
considerably. We recommend the use of our Sleipner cowls to enhance the performance and allow installation in shallow draft boats. Sleipner
cowls will also minimise the effect if stern-drives/ trim-tabs obstruct the thruster.
• Ensure there is enough space both inside and outside the transom of the boat and the thruster does not get in conflict with existing equipment
inside the boat like steerage links etc. (NB: It is possible to mount the tunnel offset from the boat’s centre line if necessary.)
• Heat protection cut off is calculated from the thruster motor. To avoid cable overheating do not install place the volt cables from the thruster to the
control box near any heat sources.

Positioning the stern thruster
EN
For best performance, the thruster must be installed as deep on the stern as possible and the thrusters water flow must not obstruct any objects.
The thruster should be installed as deep under the waterline as possible for two reasons:
1. So it does not suck air from the surface which will reduce performance and increase noise levels.
2. To receive maximum ef ciency and thrust.
The thruster must be installed to ensure the propulsion water flow must not be obstructed by other objects. Objects that obstruct the water flow will
greatly reduce the thrust output.
Position
The thruster can be installed in multiple locations on the boat transom. Installing the thruster slightly off centre will not affect the overall effectiveness
of the thruster. Installing the thruster off centre may be required to avoid any obstructions externally or internally on the vessel.
Ensure that the external stern thruster assembly does not disturb the water flow under the hull. At higher speeds, if the thruster is installed to low can
cause damage to the thruster, additional drag and unwanted water splashing.
Alignment
The thruster can be installed at a slight angle if required for the water flow to avoid obstructions. These obstructions can include propellers systems,
trim tabs or the hull. The average force the thruster propels water is 5-7 meters per sec, therefore angled installations must be as deep as possible
under the water to minimise spray breaking beyond the water surface. (NB: install the thruster at an angle only if no other suitable location can be
found.)
Max hull thickness 50mm include spacer

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.
MC_0267
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. If there is a problem with your
Ignition Protected stern thruster, please contact your dealer.
MC_0071
Installation Considerations and Precautions
EN
• Do not install the thruster in a position where you need to cut a stiffener/ stringer/ support for the hull integrity without checking with the boat
builder this can be done safely.
• Contacts/ plugs or other joints in the control 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 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 propellers.
• Keep installation within advised measurements. The entire surface is hard coated seawater resistant aluminium. Do not damage/penetrate the coat.
• The external stern thruster assembly and controller unit are ignition protected and can be installed in areas with the chance of explosive gases in
accordance to ISO 8846 and ABYC c1500. (Certi cation pending)
• Ensure that the external stern thruster assembly does not disturb the water flow under the hull. At higher speeds, if the thruster is installed to
low it can cause damage to the thruster and/ or add additional drag and unwanted water splashing.
• The recommended minimum tunnel depth from the water surface is 140mm (5,51‘) to the centre of tunnel diameter. Place the Thruster as deep as
possible for better performance and reduced noise.
• When installing the thruster ensure it does not foul existing equipment inside the boat like motor bedding etc.
• If able ensure that stern-drives/ trim-tabs do not interfere with the water flow from the thruster as this can reduce the thrust effectiveness
considerably. We recommend the use of our Sleipner cowls to enhance the performance and allow installation in shallow draft boats. Sleipner
cowls will also minimise the effect if stern-drives/ trim-tabs obstruct the thruster.
• Ensure there is enough space both inside and outside the transom of the boat and the thruster does not get in conflict with existing equipment
inside the boat like steerage links etc. (NB: It is possible to mount the tunnel offset from the boat’s centre line if necessary.)
• Heat protection cut off is calculated from the thruster motor. To avoid cable overheating do not install place the volt cables from the thruster to the
control box near any heat sources.

1. De ne the location to install the thruster. (NB: Ensure the thruster does not protrude past the transom profi le on any side and there is no
obstruction to the thrusters water flow. Also, check internally the thruster will not obstruct any objects. Ensure cables internally do not obstruct
any objects. Do not place cables or control box close to high heat radiating parts EG. Turbo/ exhaust manifolds etc.)
2. Mark the locations of the three drill holes using the de ned measurements in this manual or from a template. (NB: Maximum hull thickness is
50mm including optional spacer or 150mm for extended hull thickness models.)
3. Drill main hole, then two support bolt holes. Clean the area from dust for installation of the thruster.
4. Install a bolt and washer to ensure top bolts contact surface area is level with the main tube. Temporally place the thruster through the holes to
ensure correct  tting. Using the cable leads from the thruster de ne the location within the vessel for the installation of the control box. (NB: If
using a spacer the support bolt and washer are not required.)
5. Check the length of the compression rings. Compression rings must be longer than hull thickness to allow for compression (NB: Cut compression
sealants to length top achieve 10% compression.)
6. The thruster assembly must sit flush on the transom. Grind and sand the area if required to ensure a secure  t. (NB: Use caution when grinding/
sanding surfaces as to not remove too much fi breglass.)
7. Ensure both bolts and washers to the support bars on the thruster are attached.
Apply a sealant (MS Polymer) to:
- the inside surface of the cut-out holes on the hull.
-To the surface of the washer to the thread and
- in the recess of the main tube to the thread.
- 1cm deep inside all compression ring.
place all compression rings to bolt threads. (NB: Ensure ample sealant (MS Polymer) around the bolts and centre tube for a watertight fi tting.)
8. Insert the thruster with compression rings into the hole.
9. Fasten the thruster
MC_0074
!Please refer to the graphic for special considerations relating to your model !
For installations in high corrosive environments (saltwater) the exposed aluminium parts of the thruster must be coated with an epoxy primer
before antifouling or/and use.

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. 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.
(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.
