This helps prevent uneven loading, overheating, or efficiency losses in the turbocharger. Its robust construction also minimizes sound levels, reducing exhaust noise common in marine and industrial installations.

The manifold’s marine-grade coating protects against saltwater corrosion and exhaust gas erosion, ensuring a long service life in demanding environments. Suitable for 6V92 engines, it’s an ideal replacement for older, cracked, or corroded manifolds.

Exhaust Manifold Hardware

The reliability of an exhaust system depends heavily on its fasteners. Diesel Pro Power supplies all required hardware for a secure and lasting manifold installation, including bolts, studs, washers, and nuts engineered for high-temperature operation.

• Manifold Bolts: Made of heat-treated steel, these bolts maintain clamping force even after repeated heating and cooling cycles, preventing leaks and warping.

• Manifold Studs: Designed for proper thread engagement and uniform torque distribution, these studs keep the manifold aligned under vibration and high load.

• Washers and Nuts: Hardened washers prevent galling and distribute pressure evenly, while locknuts maintain secure fastening over long operational periods.

Together, these components create a vibration-resistant assembly capable of withstanding the extreme thermal and mechanical stresses characteristic of two-stroke turbocharged engines.

Head-to-Manifold Gasket

The head-to-manifold gasket forms a critical seal between the exhaust ports and the manifold mounting surface. This gasket must endure constant exposure to high-pressure exhaust gases and thermal expansion. Diesel Pro Power’s gasket is designed with multi-layer construction, using heat-resistant materials that prevent blowouts and leaks.

A reliable seal at this junction ensures consistent exhaust flow through each cylinder, maintaining balanced turbo boost and preventing loss of power or irregular combustion. Regular inspection and replacement of this gasket are vital to prevent performance degradation and exhaust leaks.

Turbo Riser and Riser Connector

The turbo riser and marine riser connector are essential for linking the turbocharger outlet to the exhaust system, directing hot gases safely away from the engine while minimizing backpressure.

• Marine Riser Connector: This robust component joins the turbo outlet to the exhaust piping, designed for both saltwater and freshwater applications. Its corrosion-resistant materials ensure reliable operation under continuous exposure to high temperatures and moisture.

• Turbo Flange Adaptor: Provides a precise interface between the turbo outlet and riser connection, ensuring leak-free performance. Its smooth inner surface promotes optimal exhaust flow and supports efficient turbocharger spooling.

These components work together to ensure safe gas discharge, proper turbo pressure regulation, and extended system longevity.

Turbo Riser Gasket

Positioned between the turbo riser and connecting flange, the turbo riser gasket ensures no exhaust leaks occur at high temperatures. It’s composed of reinforced material with high compression resistance, designed to handle constant expansion and contraction. By maintaining a proper seal, it sustains turbo efficiency and prevents the loss of exhaust velocity—key for achieving maximum boost performance in the 6V92 Turbo engine.

Marine Manifold Water Outlet and Fittings

Marine exhaust systems rely on controlled water circulation to maintain safe exhaust temperatures. Diesel Pro Power provides a complete range of components that ensure effective cooling and leak-free operation.

• Water Outlet Plate: Regulates coolant flow through the manifold, maintaining optimal engine temperature.

• Threaded Plates and Fittings: Available in standard thread sizes, these components connect coolant lines and sensors, allowing controlled flow to prevent overheating.

• Marine Elbows (45° and 90°): Designed for tight engine spaces, these elbows direct coolant through manifold passages while minimizing stress on joints.

Together, these fittings maintain cooling efficiency and help extend manifold and gasket life.

Insulation and Thermal Control Materials

Exhaust insulation is critical for maintaining safe engine room temperatures and protecting surrounding components. Diesel Pro Power’s high-temperature insulation tapes provide superior heat containment while improving exhaust gas velocity.
