Waterlocks/Lift-Silencers

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.

Waterlock P40R/LP45R/LP50R
For exhaust hose with inside diameters of 40 mm (1 9/16"), 45 mm (1 3/4") or 51mm (2") I.D. Provided with a plug for draining during winter time. The inlet connection of these 3 models will revolve through 360°, which greatly facilitates the installation of the exhaust assembly. There is another, even larger, waterlock for 51 mm (2") I.D. hose (shown below) which is recommended for assemblies with length greater than 4 meters. Capacity 4.25 litres.

Waterlock LP50S/LP60/LP75/LP90
For exhaust hose with inside diameters of 51mm (2"), 60mm (2 3/8"), 76mm (3") or 90mm (3 1/2") I.D.
There is a choice of three different waterlocks suitable for 51mm (2") I.D. hose. The smaller model L50R, is to be used when the exhaust line is relatively short, whereas the larger model LP50S comes into proper use with a long length of exhaust tubing. Alternatively use model LSS50. These waterlocks are provided with a drain plug. Capacity 10.5 litres.
