Product Details

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. 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.

This kit is new and high-quality cast iron construction. For tips on replacing exhaust manifolds and risers, see my eBay guide. To determine if this is the correct replacement for you, look on your current manifold for casting numbers and match them to the cross-reference below:
