Installation Considerations and Precautions
• 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 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 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. (Certifi 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.

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.
