DescriptionNew HGE 4309 exhaust riser for MerCruiser V6 and V8 marine gas engines with dry-joint style exhaust (2004 and newer). Replaces 7 degree down-angle risers (does not replace 14 degree versions). This riser will fit either side of the engine and accepts all original mounting brackets. Comes with all necessary gaskets, bolts, and plugs (see picture). Each purchase is for one riser.
Unlike many other MerCruiser dry-joint risers, these include the necessary gaskets for both raw water and freshwater cooled setups, as well as bolts (all hardware needed to mount).
