4. ELECTRIC MOTOR (12 / 24 volts)
The upper coupling (motor side) is adjusted in the factory. Position the lower shouldered
coupling on the drive leg shaft and push it down as far as it will go (lightly grease the
shaft beforehand).
Place the flexible red coupler on the drive leg side coupling, (part n° 8 on the CT100
CT125 – Spare Parts diagram, page 13)
Now fit the electric motor onto the motor support and tighten the four 10mm Ø motor
support screws alternatively (maximum torque: 40Nm).
Check there is 2mm of play (+/- 1mm) between both the two couplings.
If there is too much, or too little play, unscrew the motor side coupling screw using an
Allen key and readjust. Re-tighten the screw.
Check that the propellers turn without resistance (a little resistance due to the motor is
normal).
Ensure that air can flow freely to allow the motor to cool whilst in operation.
5. PROPELLERS
Insert the drive pin and propellers.
Check that the propellers turn without resistance (a little resistance due to the motor is
normal).
Tighten the fixing screw on the side of the propeller using a 3mm Allen key (maximum
torque: 3 Nm).
Protect your hands during this operation to avoid risks of injuries caused by the edges of
the propeller blades.
IMPORTANT: to prevent against calcium deposits that damage the seals, we
recommend that you coat the shaft and stainless steel cover with silicon grease.
6. PROTECTION GRIDS
It is possible to install protection grids, however, their installation may affect thruster
performance.
7. ELECTRICAL INSTALLATION
CAUTION: an incorrect electrical installation will cause rapid deterioration or even failure
of the thruster. Excessive voltage drop will cause premature wearing of the relays and
brushes. Special attention should be given to the quality, capacity and condition of your
batteries, aswell as cable sections used.
Ensure that all electrical connections are correctly tightened.
It is essential to install a manual battery isolator and if possible an electric
battery isolator at the base of the thruster motor power line.
When using a manual battery isolator it must be visible, clearly marked & easily
accessible.
