4.0 - Thruster positioning
• To avoid cavitation in the propeller, the tunnel must be positioned as low as possible.
• In order to prevent any damage, position the retractable thruster in such a way that the closing lid is not affected by the
propulsion cone of the boat propeller (example 1 and 2), in both directions.
• The longer L1 and L2 lengths will be, the greater will be the thrust generated around the center of gravity.
