Bow thruster

I've had a couple of questions via e mail about correct bow thruster installation. Although this is not a job that I would recommend for the average DIY boatowner installing a thruster is popular upgrade. This posting is not about the actual installation itself but it is about the difference between a bow thruster tube that is not faired in and one that is. This is a pretty neat video which shows very clearly the amount of turbulence that is generated around a tube that is not faired in. Turbulence decreases the effectiveness of the thruster and generates vibration.
