Product Description

New Sierra exhaust manifold and riser kit for Mercury/MerCruiser V8 small block marine gas engines (GM Chevrolet 5.7L/350 and 5.0L/305). Fits most engine years 1983 to 2003 that used 4-inch outlet cast iron "wet-joint" risers (see mages for comparison of wet and dry joint). 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, stainless steel, 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 ships in multiple boxes. When you receive your tracking number, be sure to track it on the carrier's website to view all packages (they may arrive on different days).

This kit is new and high-quality cast iron construction by Sierra Marine, a Dometic brand. To determine if this is the correct replacement for you, look on your current part for casting numbers and match them to the cross reference below:
