1. GENERAL INSTALLATION GUIDELINES
In order to install the thruster in the most efficient position, follow the instructions below:
• The minimum acceptable tunnel position is 139mm below the waterline
• The tunnel is ideally positioned when the distance between the waterline
and the top of the installed tunnel is 185mm
• The tunnel must be installed as far forward as possible
NB: A thruster turbine installed above its ideal position towards its minimum depth will
lead to a progressive loss of performance.
Whether inclined or horizontal, it is recommended to support the electric motor.
The batteries used by the thruster must be charged by both the main engine's alternator
and an appropriate battery charger.
If the thruster is installed using a dedicated battery bank, this must be as close as
possible to the thruster in order to reduce voltage loss in the electric cables.
For the CT60-IP mono, the propeller must be centred in the tunnel.
In the case of the CT80-IP duo, the drive leg must be centered in the tunnel
In no case should the propellers of either models protrude out of the tunnel.
NB: Two metal brackets can be found on the
front and back of the casing which can be
used to hold the thruster in place if
necessary.
