Imtra SM12013 Tunnel Aluminum 220 x 1000 x 10 millimeter | Sleipner SNEXTACC3 Depth and fast-response water-temperature sensingTunnel Selection The diameter of the tunnel will be determined by the model of bow thruster and its propeller diameter. Tunnel diameter refers to the internal diameter of the tube. The optimal tunnel length is between 2 and 4 times the tunnel diameter (measuring on the short [lower] side of the installed tunnel). Tunnels which are too short allow the propeller to cavitate which decreases performance and makes a lot of noise. Tunnels which are too long
