Featuring all the updates of its larger brother, the BOW3512F is suitable for a 125mm diameter tunnel. This means the powerful BOW3512F can be installed in even smaller boats. The flexible rubber coupling eliminates motor vibrations and the new motor is more energy-efficient. To accommodate the flexible coupling, the flange height will increase by 30mm. Apertures in the flange enable easy checking of the coupling. Last but not least, the flange face will change from triangular to round, allowing the motor to be rotated in steps of 90° as opposed to the current steps of 120°, and creating uniformity in the entire DC bow thruster range. Highlights Fits a 125mm tunnel Flexible coupling between tailpiece and motor eliminates noise New motor is more energy efficient Easy to install Single propeller creates less flow disturbance in the tunnel Unique VETUS propeller blade design minimises cavitation noise Strong synthetic propeller is resistant to corrosion and reduces weight Spiral gears minimise transmission noise Meets EMC requirements
