Mercruiser 807988Q03 4" Exhaust elbow. Original equipment quality at aftermarket pricing, magnum "E-coated" riser. Not supplied with gaskets. order gaskets separately. NOTE: Mercruiser did away with 1/8" drain at bottom of Elbow. So if you are feeding a dripless shaft log, (inboard boats only) you will need to access cooling water from another location.
