Product Description
New Sierra exhaust manifold and riser kit for MerCruiser V8 small block marine gas engines (GM/Chevrolet 5.0L 305 cu. in. and 5.7L 350 cu. in.). Fits engine years 1983 to 2003 that used 4-inch outlet cast iron risers. Accepts all factory original accessories and brackets. Kit includes 2 manifolds, 2 risers, 2 lower water fittings, and all mounting bolts, plugs, and gaskets. Each purchase is for one engine kit.

Notes
  • Does not replace "dry joint" exhaust, stainless steel risers, or 3" OD outlet risers (for 3" ID hose).
  • If you also need 3" tall riser spacer blocks, look for the Sierra 18-1908 listing.

Shipping Note: Due to the weight of these parts, this kit ships in multiple boxes. When you receive your tracking number, be sure to track it on the carrier's website and find the "Other Packages in this Shipment" section to track all of the individual boxes. For standard/ground shipments, they may arrive on different days.
