Vetus Bow Thruster - BOW3512E

Item # 886973


The quietest bow thruster in its class just got better. Introducing the BOW3512E, an upgrade of the VETUS BOW3512D. Vetus has replaced the solid motor coupling of the D-series with a flexible rubber coupling to eliminate motor vibrations. This is a similar coupling to the BOW55, with exception of the input shaft as they differ in size. The tailpieces will use the same splines as found in the BOW55.

The BOW3512E will also feature an updated motor, making it more energy efficient than the outgoing BOW3512D model. To accommodate the flexible coupling, the flange height will increase by 30 mm. 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.
