Vetus Waterlocks Type LS

It doesn't take a lot of water to kill an engine. High-capacity Vetus Waterlocks Type LS trap the large volume of water in longer exhaust systems so it can't flood back into the engine when you're sailing or bobbing up and down in choppy water with the engine shut off.

A suitable waterlock for your installation depends on the length of the exhaust system, the holding capacity needed, and the inner diameter of the exhaust hose. LS Waterlocks are available in two models to accommodate longer exhaust systems: LSS50A (2-gal. capacity; 2" ID inlet/outlet), and LSG75 (4.5-gal. capacity; 3" ID inlet/out). Both models have rotating inlet/outlet stubs for easy installation and a drain plug for winter storage.

To ensure proper sizing between port diameters and hose ID, Vetus Exhaust Hose (sold separately) is recommended for use with Vetus waterlocks.

Note: Install the waterlock at the lowest point in the exhaust system so gravity forces all water into the lock quickly, where it's collected and remains when the engine stops. The LSS model's lower height is ideal for installing in shallow bilges.
