The 818298T1 is a genuine Mercury MerCruiser Quicksilver aluminum anode kit designed to protect the bottom of the power trim pump assembly from galvanic corrosion. Mercury’s official listing identifies it for select Mercury and Mariner outboards, including all V6 and OptiMax outboards, plus selected 3-cylinder, 4-cylinder, 4-stroke, 3.4L V6, and 4.6L V8 applications.
Because this is an aluminum anode, it is suitable for saltwater, brackish water, and mixed-water use. Mercury’s current product information describes it as a pre-drilled aluminum anode with attaching hardware for fast replacement.
