Well-designed exhaust systems collect exhaust gases from the engine and discharge them as quickly and silently as possible. How does a typical Waterlock or Lift-Silencer work? As the mixture of seawater and exhaust gas enters the inlet connection, the water level rises in the tank. As the water level rises, the water surface gradually reduces the gas flow area entering the discharge pipe. The reduced area for gas flow causes a great increase in gas velocity and reduction of noise. The high speed of the gases, entering the outlet pipe, divides the water. The “mist” created by this process is transported to the highest elevation of the exhaust piping. The volume of the Waterlock or Lift-Silencer tank should allow ample accumulation of the return water once the engine is stopped.
