NLP Waterlock Mufflers both silence engine noise, and collect the cooling water present in the exhaust hose when the engine is stopped, preventing drainage back into the engine. The dual stage construction of the NLP features separate upper and lower chambers. Compared with single stage waterlocks with only one chamber, such as the Vetus LP muffler, the NLP offers superior noise reduction with minimal back pressure.
• Both inlet and outlet connectors, as well as the entire upper chamber, rotate a full 360° to greatly simplify installation – especially in confined spaces
• Synthetic material – lightweight, durable, and completely corrosion-proof
• Both chambers have drain plugs for winter storage
• Supplied with securing straps
• For 2″ hose, the larger NLP50S is suitable for longer exhaust runs compared to the NLP50
• 40mm Vetus hose for the NLP40 is available – see our Order 156482
• In the image shown, the inlet is at the bottom and is marked on the muffler

The Vetus NLP waterlock mufflers dual stage construction provides superior silencing of exhaust noise with minimal back pressure. The rotating top section and connections make instillation easy even in confined spaces.
Features:
- Separate upper and lower chambers with partition, horizontal plate and center riser tube provide better sound reduction then single chamber designs
- Top chamber and inlet/ outlet connections rotate 360°
- Drain plug makes winterizing easy
- Includes nylon mounting straps to secure muffler to the boat
- Meets ABYC Standards
- Dimensions: See Diagrams
Notes:
- Imperial dimensions are approximate, the manufacturer built this product to metric specs
- Vetus recommends installation of a VETUS NLPG Muffler and gooseneck in the exhaust line, after the NLP waterlock for optimum silencing of exhaust noise
