Ø = Tunnel Diameter.
For optimal performance the Thruster unit should
be mounted within the following:
• Chose position, ensure it is at least 1Ø below
the waterline to prevent air being sucked into
the tunnel.
• That the chosen area is flat.
• Check internal position is free of mechanical,
electrical or bulkhead obstructions.

• The thruster must be in a watertight enclosure
that is a minimum of 150 mm (6”) above the

and routed around the enclosure.
