MERCRUISER V6 & V8 14 DEGREE RISER DRY JOINT

MerCruiser V6 & V8 14-Degree Dry Joint Riser – High-Performance Exhaust Flow & Engine Protection

The product  is a robust and reliable solution designed to optimize exhaust flow and prevent water reversion in MerCruiser V6 and V8 engines. Built to withstand the harsh marine environment, this OEM-style riser is a direct replacement for 4.3L V6 and 5.0L, 5.7L, and 6.2L V8 engines using MerCruiser’s dry joint manifold system.

With its 14-degree angle, this riser delivers improved elevation and water separation, helping to reduce the risk of water backflow into the exhaust system—especially critical during engine shutdown or low-RPM operation. This added protection helps safeguard your engine from costly internal corrosion or hydrolock.

What truly sets the dry joint riser system apart is its advanced water routing design. Unlike wet joint risers that allow water to pass through the gasket surfaces, dry joint risers isolate the coolant flow in a separate chamber. This prevents leaks and gasket failures, greatly improving the durability and reliability of your exhaust system.

Made from heavy-duty marine-grade cast iron and finished with a high-temperature corrosion-resistant coating, the MerCruiser 14-degree riser is built to last in both saltwater and freshwater conditions. When paired with a MerCruiser dry joint manifold, it forms a solid, dependable exhaust system that supports engine longevity and consistent performance.

Whether you’re replacing old components or upgrading your system, this riser is compatible with standard MerCruiser dry joint manifolds and is easy to install with matching gaskets and hardware.

For boaters who value performance, protection, and peace of mind, the MerCruiser V6 & V8 14-Degree Dry Joint Riser is a smart investment in your engine’s health and long-term reliability.
