Gasket, Water Pump
The Honda 19242-ZV5-000 Thermostat Cover Gasket is a genuine OEM sealing gasket designed for select Honda BF-series marine outboard engines. This precision-cut gasket creates a reliable, leak-free seal between the thermostat housing and engine block, ensuring proper cooling-system pressure and preventing water or coolant leakage. Manufactured from high-quality, heat- and water-resistant material, it withstands harsh marine conditions, vibration, and long-term temperature cycling. Ideal for thermostat service or replacing a worn, brittle, or leaking gasket, this OEM part restores factory-spec cooling performance and helps protect your outboard from overheating.
