Why Buy OEM

Mercury’s OEM anodes are cast from the exact aluminum blend needed for balanced protection and slow, even wear. Many aftermarket versions use impure metals that don’t protect evenly or last as long.

A genuine Quicksilver anode fits perfectly, wears predictably, and provides the kind of protection Mercury designed your motor to have from day one.
