Electric Tunnel Thruster CT 300

Name: Electric Tunnel Thruster CT 300
Brand: Max Power

Max Power CT300 electric tunnel thruster: twin-propeller unit with bronze drive leg for 300 mm tunnels; 300 kg (24 V) or 275 kg (48 V) thrust; for yachts 48–93 ft.

Description

The Max Power CT300 is an electric tunnel thruster for the popular 300 mm tunnel diameter, suited to motor yachts and deep-keel sailing boats of 48–93 ft. The 48 V version is a direct replacement for older, less powerful 24 V units.

Key features

Twin propellers, bronze drive leg
48 V version: 48% lower current draw and 50% longer operating cycle than the 24 V equivalent, allowing smaller cables and supply from the house batteries

Technical data

24 V (code 317606): 300 kg (660 lbs) thrust, 19.7 kW (26.4 hp), 58.5 kg
48 V (code 636656): 275 kg (606 lbs) thrust, 17.5 kW (23.8 hp), 64 kg
Tunnel diameter: 300 mm (tunnel wall 9–10 mm)
Dimensions A/B/C: 250 / 250 / 480 mm

Performance notes

Thrusters are rated at 10.75 V on 12 V units and 22 V on 24 V units; higher voltages give higher thrust and power consumption but a reduced duty cycle
Performance data applies at an immersion depth of one tunnel diameter, in a tunnel no longer than twice its diameter (± 6%); longer tunnels reduce thrust and increase consumption
