REMOTE INSTALLATION OF THE ELECTRONIC BOX.
As the electronic controlbox and its contact are the most sensitive parts on the thruster, we advice that these are
removed from the thruster and fitted in a high place in the boat so to secure these from water ingress, even if the
thrusters compartment gets flooded.
Included with the stern-thruster tunnel kit is an extension cable that will allow you to do this.
Procedure:
1 Exchange the GREY and BLUE wires on the sides of the main solenoids that is coming from the
electronic controlbox with the GREY and BLUE wires from the extension cable.
2. Exchange the BLACK, BROWN and WHITE wires from the electronic controlbox with BLACK ,
BROWN and WHITE wires in the extension cable.
3. Cut the strips holding the RED internal connections together with the other internal connections,
and leave the RED wires on the main solenoids. Cut the red wire in accordance to drawing.
4 Remove the electronic controlbox and its harness from the solenoid system on the thruster.
5 Locate and fasten the electronic controlbox in a position where it will surely keep dry. This should
be relatively high in the boat, so that even an extreme level of bilge water can not get to it. Also
ensure that the position is safe against water running from above.
6 Remove the electronic controlbox from its original harness and plug it into the connector on the
extension cable.
7. The extension cable to the control panel(s) must now be connecte to the AMP male plug on this
remotely installed controlbox. Ensure that all controlcable junctions/connectors are placed so that
they will stay dry at all times.

ELECTRICAL INSTALLATION OF STERNTHRUSTER SYSTEMS
PS ! This is additional information especially for sternthruster installations, and the installation
manual for the thruster you are installing must be used complementary.

If a bow thruster is also installed, we strongly advice to use seperate battery banks for the two
thrusters to avoid extreme voltage drop if both thrusters were to be used at the same time, and to
ensure maximum performance.
Battery banks must have common minus!
Refer to the thruster manuals for advised battery capacity and cable sizes for each thruster.
If a single control panel other than Sidepower’s is to be used for both bow and stern thruster,
be sure it has a single positive connection from only one of the two thrusters to avoid current
leakage between the two battery banks. If you are installing the standard Sidepower dual
joystick panel this is already taken care of.
