Vetus NLP37515L Rotatable Waterlock/Muffler for 75 mm Exhaust Hose – 15 L Capacity
The Vetus NLP37515L is a high-performance three-chamber marine waterlock/muffler engineered to deliver maximum sound attenuation and minimal back pressure in water-injected exhaust systems. Its advanced three-chamber design provides a remarkable 10 dB noise reduction compared to traditional two-chamber waterlocks, making it one of the quietest solutions available for marine engines. The fully rotatable inlet chamber and 360° rotatable hose connectors simplify installation significantly, even in restricted engine compartments. With a 15-liter capacity and low overall height of only 155 mm, this model offers increased flexibility and supports longer exhaust hose runs—up to 1.5 times the length permissible with 10-liter NLP3 units.
