Product data sheet Typical boat size: Tunnel diameter (inside): Tunnel thickness: Performance data: The twin propeller CT HYD 325 has a bronze (or aluminium) drive leg, and is available in 2 models the CT325/250 or the CT325/325 Currently the largest unit in the hydraulic tunnel thruster range, this model has a 315mm tunnel diameter, a thrust rating of up to 275 / 606 (kg/lbs) and integrates all the unique features of the range. Unique Features: drive legs Case hardened spiro-conical gears Control Panels: Max Power's thruster control systems include a variety of advanced safety features. • Childproof activation •Automatic shutdown after 30 minutes of inactivity •Visible and audible overheat warning •Time delay switch bewteen port and starboard thrust • Software protection against short circuits NB. Performance data is given for a thruster installed at one tunnel diameter immersion depth, 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.
