Salt, humidity, and constant vibration can destroy a generic component in a single season. That’s why choosing a genuine Mercury Marine part matters. The 8M0090697 is built to the exact specifications required by older MerCruiser engines, with sealed construction, corrosion-resistant materials, and correct torque output. Aftermarket versions might crank, but they rarely match the longevity, fitment precision, or reliability of OEM equipment.
