Mercury’s OEM components are engineered to the same standards used in new MerCruiser engines, ensuring reliable cooling and a long service life — especially in demanding saltwater conditions. It’s protection you can count on, built by the same people who designed your engine. FAQ Q1: What engines does this housing fit?
