Waterlock Silencer – 40/45/50mm

The Waterlock Silencer – 40/45/50mm is engineered to reduce exhaust noise while preventing water from flowing back into the engine. By combining a waterlock and muffler in one unit, it effectively traps cooling water and dampens exhaust sound. As a result, your vessel operates more quietly and safely.

Durable Marine-Grade Construction

Manufactured from high-density polyethylene, this silencer is built to withstand harsh marine environments. It resists corrosion, heat, and vibration, ensuring long-term reliability even under demanding conditions. In addition, its lightweight yet robust design makes it ideal for small to medium vessels.

Versatile Hose Compatibility

Designed for flexibility, this unit suits wet exhaust systems with 40mm, 45mm, or 50mm hose diameters. The stepped inlet and outlet tails can be trimmed to the required size, allowing for easy customisation. Consequently, installation is straightforward and adaptable to a range of setups.

Improved Engine Protection

Not only does the Waterlock Silencer reduce noise, but it also protects your engine from water ingress. By retaining water within the chamber, it minimises the risk of backflow into the engine. However, for optimal performance, it is recommended to install a gooseneck and siphon break where required.

Easy Installation and Practical Design

Another key advantage is its user-friendly installation. The unit connects using standard exhaust hose clamps, making it suitable for small craft and DIY installations. Furthermore, its compact size and efficient layout allow it to fit neatly within engine compartments.

Cost-Effective and Reliable Solution

Ultimately, the Waterlock Silencer – 40/45/50mm provides a practical and affordable solution for exhaust noise reduction and engine protection. With its durable construction and versatile fitment, it enhances both performance and reliability.

In summary, this waterlock silencer delivers effective noise reduction, dependable water management, and durable marine-grade performance—making it an essential component for wet exhaust systems.
