Gasket, Water Pump
The Honda 19242-ZW1-B00 is an OEM water-pump case gasket designed for Honda outboard engines. It provides a precise, watertight seal between the pump housing components, ensuring proper cooling-system operation and preventing leaks. Built from durable, heat-resistant material, this gasket is engineered to withstand high-pressure marine environments and long-term exposure to water and vibration. Ideal for use during impeller or water-pump service on models such as Honda BF25 / BF30 / BF40 / BF50 outboards. Always confirm fitment before installation.
