Electric Tunnel Thruster CT 325

The largest and most powerful model in the MAX POWER 48V tunnel thruster range, the CT325 is suitable for motor boats and deep footed sailing yachts from 51’ up to 100’.

This high performing 48V DC tunnel thruster is available with bronze and aluminium drive legs depending on the material of the hull.

Construction and Components

• Drive leg: Bronze or aluminium drive leg
• Gears: Case hardened spiro-conical gears
• Shields: Line shields
• Motors: Purpose-built 48V DC motors
• Control boxes: 24V Electronic control boxes for unrivaled safety features
• Connections: Safe, high-power connections
• Contactors: Purpose-built 24V DC contactors with high specifications

With the 48V variant we have 48% decrease in amperage consumption and 50% increase in operation cycle, in relation to the 24V equivalent model, which makes it a cost efficient solution (smaller cables, supply from the same home batteries which results in lower installation costs).

* Thrusters are designed to run at 45.6V on 48V units. Higher voltages will result in higher thrust ratings, higher power consumption, and a reduced duty cycle.

* Performance data is given for a thruster installed at an immersion depth of one tunnel’s diameter, in a tunnel no longer than twice the tunnel’s diameter, and this within a variation of + / - 6%. Longer tunnels will result in lower thrust ratings and higher power consumption.
