Detroit Diesel Marine Exhaust Manifold

The Detroit Diesel Marine Exhaust Manifold is engineered to handle the extreme thermal demands of turbocharged 8V92 marine engines. Constructed with high-grade cast iron and precision-machined for perfect alignment, it ensures efficient exhaust gas flow from the cylinders to the turbocharger inlet. This manifold fits 8V92 Turbo engines as well as select 16V92 configurations used in marine propulsion systems.

Each manifold is coated to resist corrosion from seawater exposure and thermal cycling. In marine applications, exhaust manifolds are also designed to prevent hot spots and to work in harmony with water-cooled elbows or risers to manage temperatures safely.

Features:

• Built to OEM specifications for the Detroit Diesel 8V92 Turbo

• Compatible with marine and industrial configurations

• Improved thermal stability and corrosion resistance

• Supports efficient gas flow to maintain turbo pressure and reduce backflow

Water-Cooled Turbo Exhaust Manifold

The water-cooled turbo manifold for the Detroit Diesel 8V92 Turbo engine is a key component that merges exhaust routing with cooling efficiency. This manifold is fully rebuilt to original Detroit Diesel standards and is ideal for engines running in enclosed spaces or high-temperature marine environments.

The integrated water jacket keeps exhaust temperatures manageable, preventing overheating and ensuring compliance with marine safety requirements.

Key Advantages:

• Rebuilt to OEM precision standards

• Ideal for continuous-duty turbocharged marine engines

• Reduces surface temperatures and minimizes fire hazards

• Enhances turbo efficiency by maintaining exhaust gas velocity

Exhaust Manifold Bolts, Studs, and Nuts

A properly sealed and secure exhaust system starts with OEM-quality hardware. Diesel Pro Power supplies exhaust manifold bolts, studs, washers, and nuts for the Detroit Diesel 8V92 Turbo that ensure leak-free connections between the manifold, head, and turbo assembly.

• Bolts for Exhaust Manifold: Heavy-duty fasteners designed to withstand vibration and heat cycles without loosening.

• Studs for Exhaust Manifold: Provide consistent torque and easy installation, especially in marine engines with restricted access.

• Washers and Nuts: Precision-threaded for the 7/16”-14/20 configuration commonly found in Detroit Diesel Series 92 engines.

All hardware is corrosion-resistant, ideal for marine or coastal environments where salt exposure can lead to premature failure.

Turbo Riser Adaptors and Flanges

Turbo riser adaptors and flanges are critical transition components connecting the manifold to the turbocharger and exhaust piping. Diesel Pro Power carries precision-machined riser adaptors and flanges tailored for the 8V92 Turbo engine.

• Turbo Riser Adaptor (4" ID): Built to withstand extreme turbo outlet pressures and temperatures.

• Turbo Flange (3.125” ID): Provides a secure connection between turbo and riser assemblies.

These components ensure that exhaust gases flow smoothly with minimal turbulence, which improves turbo response and engine efficiency.

Benefits:

• Prevents exhaust leaks at high pressure

• Machined for exact fitment on Detroit Diesel 8V92 Turbo configurations

• Made from high-strength stainless or cast steel for marine durability

Gaskets for Manifolds and Turbo Connections

Exhaust gaskets are small yet vital components that preserve system integrity by preventing leaks. Diesel Pro Power provides every gasket required for the 8V92 Turbo exhaust system, including:

• Head-to-Manifold Gaskets: Seal between cylinder head and manifold to prevent gas escape.

• Turbo Riser Gaskets: Maintain pressure between turbocharger and riser assembly.

• Marine Manifold Flange Gaskets: Designed to handle high heat and water exposure, these gaskets ensure the marine manifold remains tightly sealed.

• Water Outlet Gaskets: Used on manifolds with integrated cooling passages.

All gaskets are made from reinforced graphite or multi-layer steel, depending on location, ensuring resilience under sustained turbo boost and heat exposure.

Marine Exhaust Flanges and Outlet Plates

The Detroit Diesel 8V92 Turbo exhaust system relies on water-cooled flanges and outlet plates to safely manage exhaust gas discharge. The marine exhaust manifold flange includes precision threading for easy connection with elbows or outlet pipes.

• Marine Manifold Flange: 4” NPT threading ensures secure pipe connection.

• Water Outlet Plate: Regulates coolant discharge from the water-cooled manifold to the exhaust outlet.

These components are corrosion-resistant and engineered to function in marine conditions where constant exposure to moisture and salt would otherwise degrade materials.

Marine Manifold Elbows and Fittings

To route exhaust gases safely, the 8V92 Turbo exhaust system includes 90° and 45° elbows. Available in ¾” and 1” thread sizes, these fittings connect the manifold to cooling and exhaust discharge lines.

Elbow Options:

• 90° Elbow (1” Thread): Common in larger exhaust water outlet configurations.

• 90° Elbow (¾” Thread): Suited for smaller marine connections.

• 45° Elbow (¾” Thread): Used where space constraints require angled routing.

All elbows are made from corrosion-resistant metal with precision threading for watertight seals.

Insulation Tape for Exhaust Systems

Managing exhaust heat is vital for both performance and safety. Diesel Pro Power offers manifold insulation tape in 3” and 4” widths, each 100 feet long and 1/8” thick.

Applications:

• Wraps around exhaust manifolds, risers, and pipes to reduce radiant heat

• Protects surrounding components from damage

• Reduces noise and vibration from exhaust flow

This insulation is especially important in marine applications where confined engine rooms demand controlled temperatures.

Flexible Metal Exhaust Hoses

For connecting the manifold outlet to exhaust piping or mufflers, flexible metal hoses offer durability and vibration resistance. Diesel Pro Power supplies hoses in 4-inch, 6-inch, and 8-inch diameters, each 18 inches long.

Features:

• Constructed from stainless steel for marine corrosion resistance

• Threaded for easy installation

• Absorbs vibration and misalignment in exhaust routing

• Suitable for high-heat, high-pressure turbo exhaust flow

These hoses ensure smooth exhaust discharge and protect against structural stress on fixed exhaust components.

Gasket for Marine Manifold Spacer

The marine manifold flange spacer gasket maintains a perfect seal between manifold sections or between the riser and manifold flange. Its reinforced design allows it to endure temperature spikes common in turbocharged exhaust systems.

Specifications:

• Outer diameter: 6.25"

• Inner diameter: 3.50"

• Ideal for sealing riser-to-manifold connections

This gasket prevents leaks that could reduce turbo pressure or allow seawater to infiltrate the exhaust path.

Muffler Caps for Industrial Applications

For stationary or industrial 8V92 Turbo engines, Diesel Pro Power provides muffler caps ranging from 3” to 5” diameters. These caps protect the exhaust system from moisture and debris ingress when engines are not in operation.

Sizes Available:

• 3.0" OD

• 3.5" OD

• 4.5" OD

• 5.0" OD

Each cap is precision-made to fit standard Detroit Diesel industrial mufflers and prevent corrosion from internal moisture accumulation.

Paint and Protective Coatings

A professional engine finish extends the life of your 8V92 Turbo. Detroit Green Paint—authentic to the original factory color—is available in aerosol form for convenient application. Suitable for cast iron, steel, and aluminum surfaces, it resists oil, fuel, and salt corrosion.

Usage:

• Ideal for manifolds, blocks, and valve covers

• Provides OEM color match and heat resistance

• Available for shipment within the U.S. and Canada

Temperature Switch

To maintain safe operating temperatures, the temperature switch automatically closes the circuit at 205°F, alerting operators or triggering alarms when coolant temperatures exceed safe thresholds. Compatible with Detroit Diesel, Cummins, and Caterpillar engines, it features a ½” NPT thread for easy installation.

Gauges and Monitoring Equipment

Diesel Pro Power also offers a complete selection of mechanical and electrical gauges for 8V92 Turbo installations. Options include:

• Standard mechanical gauges for direct engine monitoring

• Alarm-equipped versions for safety compliance

• 12V and 24V electrical gauges for marine control panels

These instruments ensure operators maintain visibility over temperature, oil pressure, and turbo performance in real time.
