Installation Notes

Ensure the engine is off, cooled down, and disconnected from the power source before beginning.
Disassemble the powerhead according to the official Mercury Marine service manual for your specific Verado engine model.
Thoroughly clean all mating surfaces to remove any old gasket material, sealant, oil, and corrosion. Use a plastic scraper and appropriate solvent to avoid damaging the metal surfaces.
Carefully place each new gasket, ensuring it is correctly aligned with all bolt holes and passages. Do not use any additional sealant unless explicitly specified by the service manual.
Reassemble the powerhead, torquing all bolts to the manufacturer's specified values and sequence. Incorrect torque can lead to leaks or component damage.
