Our range of Side Thrusters are fitted with the standard Hydromaster gearboxes. Using a large reduction allows for relatively large propeller diameters, producing more thrust at a lower input power. Tunnel Thrusters are standard fitted with a stainless steel wear ring in a steel or aluminium tunnel.
