Hi Noah,

Yes, you can use Sea Foam in your Mercury! Another great option is Sea Foam Marine PRO. It’s specially formulated for marine engines and gives boat owners everything they want in a fuel system treatment – it cleans fuel passageways, lubricates, stabilizes fuel, and provides corrosion protection to upper engine areas.

Hope this helps!
