What are you looking for?

High-performance noise cancellation for your boat. The unique three-chamber design technology makes these an incredible 10dB quieter than our already very quiet traditional waterlocks.

The inlet chamber of this extremely quiet waterlock can be rotated 360° to ensure a tailor-made fitment even in the most confined spaces. As with its smaller siblings, the 15lt version of the NLP fits multiple hose diameters: 60, 75 and 90mm. This, combined with its very low height (only 155mm), makes this waterlock your ideal partner for engines of 49-110hp (36-81kW), with a back pressure of only 0.1 bar or less. With the increased capacity enabling the use of an exhaust hose up to 1.5 times longer than with the 10lt NLP3s, purchasers have more freedom to install the waterlock in a convenient place.
