18-1907 Manifold Riser

Replace corroded or freeze damaged risers easily

Exhaust risers and manifolds have a tough life. Constant exposure to salt and fresh water and heat cycling promotes corrosion resulting in failure sooner than other engine parts. Inspection and consequent replacement is common. Sierra makes the task of replacing risers easier.

Sierra risers are designed for a quick installation. Each riser is an exact OEM match and is leak tested for quality assurance. Mating surfaces are CNC machined to provide the best possible seal without additional preparation. Precision castings feature uniform wall thickness. Finally, they are primed and painted to stand up to the marine environment. Look no further than a Sierra kit for quick out of the box installations
