Detroit Diesel Marine Exhaust Manifold for 16V71 Turbo Engines

The marine exhaust manifold serves as the foundation of the exhaust system on the Detroit Diesel 16V71 Turbo engine. Designed to collect exhaust gases from each cylinder and direct them efficiently toward the turbocharger or exhaust outlet, this manifold is engineered for both reliability and thermal balance.

Constructed from heavy-duty cast iron, the manifold resists cracking under the extreme temperature fluctuations typical of marine operations. The water-cooled design helps maintain manageable surface temperatures, reducing stress on surrounding components and minimizing corrosion risk.

This same manifold design is compatible with multiple engine configurations including the 8V71, 8V92, and 16V92, but for the 16V71 Turbo it delivers the ideal exhaust flow and balance needed for optimal turbocharger performance. Replacing a damaged or eroded manifold can restore lost horsepower and fuel efficiency—an investment that pays back through smoother power delivery and longer engine life.

Detroit Diesel Turbo Riser Adaptor

The turbo riser adaptor bridges the turbocharger outlet with the marine exhaust elbow or piping system. On the Detroit Diesel 16V71 Turbo, this adaptor must withstand high exhaust gas temperatures and pressures while maintaining a leak-free seal.

Made from precision-machined steel, it features an inner diameter of 4 inches and an outer diameter of 6.25 inches, providing ideal flow for turbocharged exhaust gases. The adaptor’s height of 1.125 inches ensures proper alignment with existing exhaust configurations in confined marine engine rooms.

Diesel Pro Power supplies this adaptor ready to install with standard marine hardware. Its robust construction ensures resistance to vibration, thermal cycling, and corrosion—key concerns in saltwater environments.

Detroit Diesel Head to Manifold Gasket

Every cylinder head connects to the exhaust manifold using high-strength gaskets designed to handle intense temperature and pressure fluctuations. For the Detroit Diesel 16V71 Turbo engine, these head-to-manifold gaskets provide a tight seal between cast iron surfaces, preventing leaks that can reduce exhaust velocity and engine efficiency.

Each gasket is constructed from reinforced material capable of withstanding extreme heat and maintaining its shape under continuous stress. Proper sealing also prevents oxygen leaks that could skew exhaust readings or reduce turbo performance.

Technicians typically replace these gaskets during major overhauls or whenever the manifolds are removed for cleaning or inspection. Diesel Pro Power ensures quick availability so operators can minimize downtime.

Detroit Diesel Gasket for Marine Exhaust Manifold Flange

The marine manifold flange gasket ensures a proper connection between the exhaust manifold and its adjoining flange. The gasket’s dimensions—6.25 inches outer diameter and 4.25 inches inner diameter—are engineered for the large-bore exhaust passages of the Detroit Diesel 16V71 Turbo.

Manufactured from multi-layer composite material, it resists blowouts, moisture intrusion, and exhaust gas leakage. In high-output marine engines like the 16V71, maintaining a sealed exhaust path is essential for consistent turbo spool-up and avoiding backpressure issues.

Detroit Diesel Turbo Riser Gasket

The turbo riser gasket creates a precise seal between the turbo riser adaptor and the exhaust outlet flange. Measuring approximately 3.75 by 5.5 inches, it ensures that no exhaust gases escape under pressure.

A degraded turbo riser gasket can lead to power loss, black smoke, and noise—symptoms that indicate improper exhaust routing. Diesel Pro Power offers these gaskets ready to ship, providing reliable sealing for all turbo riser configurations on 16V71 Turbo engines.

Detroit Diesel Marine Exhaust Manifold Flange

This threaded marine exhaust manifold flange (4” NPT thread) is the junction where exhaust gases transition from the manifold into the piping or cooling sections of the system. Crafted from marine-grade alloy steel, it resists pitting and rust formation even in corrosive seawater conditions.

The flange’s precision threading ensures secure fitment with minimal vibration loosening, while its smooth internal surface maintains laminar exhaust flow. Diesel Pro Power’s flange solutions allow seamless replacements during manifold rebuilds or custom exhaust configurations.

Manifold Insulation Tape – 3” and 4” Widths

Exhaust insulation tape is crucial for thermal management in confined engine rooms. For the 16V71 Turbo, which produces substantial exhaust heat under load, insulation tape minimizes heat radiation, protecting wiring, hoses, and nearby components.

Available in 3-inch and 4-inch widths, each roll measures 100 feet long and 1/8-inch thick. The fiberglass-reinforced material withstands temperatures exceeding 1000°F. Technicians use this tape to wrap around manifolds, elbows, or risers, promoting safety and efficiency.

Diesel Pro Power’s insulation tapes are ideal for shipyards and engine service technicians who prioritize long-term reliability and neat installation results.

Detroit Diesel Manifold Studs, Crabs, Washers, and Nuts

A complete exhaust installation relies on secure fasteners. The manifold studs (7/16"-14/20 x 2.10") provide strong threaded anchors to attach manifolds and gaskets to the engine block.

The manifold crabs distribute clamping force evenly along the manifold surface, reducing stress and ensuring leak-free sealing. Combined with durable washers and nuts, these components create a robust connection that resists loosening due to vibration or thermal cycling.

Replacing worn or corroded studs and nuts is essential during any manifold or gasket replacement. Diesel Pro Power offers factory-quality replacements to maintain original torque integrity and alignment.

Detroit Diesel Marine Manifold Water Outlet Plates and Gaskets

The marine manifold water outlet plate and its matching gasket play a critical role in controlling the flow of coolant through the exhaust manifold. In water-cooled turbo systems such as the 16V71 Turbo, this ensures proper exhaust gas cooling and prevents overheating of surrounding areas.

These components are made from corrosion-resistant materials that can withstand exposure to saltwater. Proper gasket sealing prevents leaks and maintains cooling efficiency—essential for marine vessels operating under continuous duty cycles.

Detroit Diesel Threaded Plates and Elbows

The threaded plate (3/4” thread) for marine manifolds allows the secure installation of fittings, sensors, or coolant elbows. Each plate requires two bolts (5/16”-18 x 1 1/8”) and features heavy-duty threading that prevents stripping during repeated maintenance cycles.

The 90° elbows—available in 3/4" and 1" thread sizes—connect coolant or exhaust hoses at sharp angles, allowing compact routing in tight spaces. The 45° elbow variant provides more gradual bends to reduce flow restriction.

All elbows are manufactured with marine-grade brass or bronze to resist corrosion and heat fatigue, ensuring long-term reliability in saltwater environments.
