Vetus, Waterlock Muffler for Long Exhaust Systems, LSS. Sometimes, notably in the case of sailboats, the exhaust hose is so long that an extra large waterlock is needed to prevent the large volume of water in the line from running back into the engine once it has been stopped. The LSS mufflers provide the extra capacity to help keep your engine safe. At a mere 8-7/8" high, the LSS models are well-suited for shallow bilges.
