positioning and then tightening the two 8mm ∅ screws alternatively using a 5.5mm Allen
key (maximum torque: 25Nm).
Check that the propellers rotate freely, without resistance or friction.
It is imperative that the holes and the screws remain free of sealing compound,
otherwise there is a risk of an incorrect assembly of the parts.
Caution: do not use graphite grease.
NOTE:
The composite drive leg:
• is pre-filled with oil and sealed for life
• does not require anodes
• must not be disasembled, even partially (exclusion waranty)
4. ELECTRIC MOTOR (12 volts)
After having greased the motor shaft and the drive pin, place the motor on its support.
The motor should centre itself and align easily when correctly mounted on its support.
If not, the drive leg, motor support and tunnel are incorrectly assembled. Most likely due
to an uneven surface on the outside radius of the GRP tunnel.
If this is the case dissasemble the motor support / drive leg assembly, sand the tunnel so
as to achieve a smooth exterior radius and repeat the previous steps.
Position the four 8mm ∅ motor support screws, then tighten them alternatively (maximum
torque: 30Nm)
5. PROPELLER(S)
Insert the drive pin and propeller (to be carried out twice for the CT80 duo).
Check that the propeller(s) turn(s) 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.
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 GRILLS
It is possible to install protection grills; however installation of such grills will 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.
