804532 Oring Kit Mercury OEM

804532 Oring Kit Mercury OEM This O-Ring kit is used on variouse OptiMax V-6 Fuel Rails. This kit includes more orings than what you will use. I could never figure out why Mercury forces dealers to carry so many, other than the cost is cheaper to package and ship in quantities. So here at Boating Solutions we sell and price them as 1 ea. Fits Optimax 115HP 1.5L DFI through 300HP 2.5L DFI Engines including Sportjet.
