    Description

    For All
    MerCruiser 350 with 4" elbows 1983-2001
    -No Spacer In the V8 GM Small Block,
    GLM's fully tuned design guides exhaust gases directly to the riser without turbulance and back pressure. This increases the engine's performance by 10%. These GLM manifolds also feature an additional 40% increase in water cooling area that decreases the manifold's overall body temperature significantly. In GLM's MerCruiser replacement 4 inch riser, there are two additional water jackets. This allows a higher volume of water to flow through the riser, keeping the engine cooler. *All manifolds and risers are powder coated black for maximum corrosion protection.
    If your Engine is newer than 2002, you likely have a Dry Joint Manifold and this Manifold will not work! Please review the image in the listing with your gasket to determine your type of manifold.
