Vetus NLP50 Rotatable Waterlock Muffler, Dual-Stage, 51mm Hose, 4.5 L

The Vetus NLP50 is a dual-stage marine waterlock muffler (also called an exhaust waterlock) that quiets engine exhaust noise with minimal back pressure. It is made for wet exhaust systems and connects to an exhaust hose with a 51mm inside diameter. Its capacity is 4.5 litres.

Key Features:

• Dual-stage construction with upper and lower chambers, a horizontal partition plate and a riser tube through the centre
• Silences exhaust noise well while keeping back pressure low
• The top chamber and both the inlet and outlet connectors rotate 360°, which makes installation easier in confined engine spaces
• Fits a 51mm inside diameter exhaust hose
• 4.5 litre capacity
• Comes with two securing straps
• Includes mounting brackets for bulkhead or floor mounting

For even quieter exhaust noise, a Vetus muffler and gooseneck can be added after the waterlock.
