Learn more about Waterlocks
The waterlock is an essential component of the exhaust system that prevents water from entering the engine by blocking exhaust gases while maintaining efficient ventilation.
Made from heat- and corrosion-resistant materials, often stainless steel, the waterlock ensures optimal performance and increased durability in harsh marine conditions.
Compatible with gasoline or diesel inboard engines, our models meet OEM specifications, ensuring simple installation and perfect compatibility with your engine.
