The EX70 Compact External Single Bow Thruster provides 148 lbs/67kg of thrust at 23V, with a tunnel diameter of 165mm. It requires a minimum depth of 5.9″ (150mm) at the top and 9.5″ (240mm) at the center. Ideal for vessels ranging from 32-42′ (9.5-13 m), typically 35-53′ (12-16 m) in length. With a power of 3.0kW at 21V, it is a compact and efficient solution for improving maneuverability at the bow.

The EX series Bow Thruster can be installed in most boats between 20 and 45 feet. These pod thrusters are an excellent choice where a tunnel thruster cannot fit, or as an extremely compact stern thruster. They are also especially good for retrofitting. The flexible mounting at the extreme bow of the boat hull allows a deeper position underwater which creates an optimal leverage compared to conventional thrusters.


  • Optimally streamlined design
  • Hydrodynamic shape, very short flow-channel and ideal placement reduce water resistance
  • Easy installation, only requires the drilling three small holes to install
  • Lower install cost due to simplified install
  • Reduced noise based on optimal tunnel shape and submerged motor
  • Longer duration based on water cooling of motor and housing
  • Space saving, less interior equipment needed
