Imtra SM13021 Tunnel Steel 303 x 2000 x 10.3 millimeter | Sleipner MELCOUR3 Commodore’s ultra-quiet motorTunnel 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
