Parts for Detroit Diesel 6V92 Non-Turbo – Marine Water Pump Section

Overview of the Detroit Diesel 6V92 Cooling System

The Detroit Diesel 6V92 non-turbo marine engine is a legendary two-stroke diesel built for reliability, power, and endurance in heavy-duty marine service. Whether installed in commercial vessels, workboats, tugs, or pleasure craft, its ability to maintain consistent operating temperature is critical for long-term performance.

At the heart of the cooling system is the raw (sea) water pump, which draws cool seawater through the hull and circulates it through the heat exchanger, aftercooler, and exhaust manifold. This process keeps the engine temperature stable and prevents overheating in continuous operation.

Because marine environments are harsh, Detroit Diesel engineered the 6V92’s sea water pump to withstand salt exposure and corrosion. The pump uses bronze housings, stainless-steel shafts, and neoprene impellers designed to perform even in demanding conditions. Diesel Pro Power supplies both new and rebuilt marine water pumps that meet or exceed OEM standards, ensuring that your Detroit Diesel 6V92 performs efficiently for years to come.

Repair Kits and Seal Components

Every marine cooling system eventually needs attention. Diesel Pro Power supplies complete water pump repair kitsdesigned for Detroit Diesel Series 53, 71, and 92 marine engines.

Repair Kit for 2½” Impeller Pumps

• Includes seals, bearings, wear plate, and gaskets.

• Restores full pumping efficiency to smaller Detroit Diesel marine pumps.

• Ideal for preventative maintenance during seasonal overhauls.

Repair Kit for 3½” Impeller Pumps

• Contains all critical seals, gaskets, and bearings for spline-shaft pumps.

• Designed for heavy-duty marine operation with long-life materials.

• Prevents leaks, shaft wear, and flow loss.

Gaskets and Sealing Components

A watertight cooling system relies on the proper gasket configuration. Diesel Pro Power provides all required sealing components for installation or rebuild of 6V92 water pumps, heat exchangers, and related fittings.

• Marine Water Pump Gaskets – Used at the inlet and outlet of the raw water pump; each pump requires two.

• Mounting Gaskets – For secure, leak-proof installation of the pump to the flywheel housing.

• Cover Plate and Flywheel Gaskets – Maintain pressure integrity and protect from seawater intrusion.

• Plate and Housing Gaskets – Designed for corrosion-resistant sealing between metal surfaces.

All gaskets are precision-cut from marine-grade materials to resist heat and saltwater corrosion.

Thermostats and Seals for Temperature Regulation

Detroit Diesel 6V92 engines operate best when maintaining a steady temperature. Diesel Pro Power offers thermostats calibrated for 160° and 170° Fahrenheit, ensuring proper coolant flow during warm-up and under load.

• 160° Thermostat – Commonly used for cooler ambient conditions or engines operating at lower RPM ranges.

• 170° Thermostat – Ideal for heavy-load applications or tropical climates where maintaining higher temperature aids efficiency.

• Thermostat Seals – Provide leak-free seating in the housing.

These components ensure accurate temperature control, preventing overheating and improving overall performance.

Heat Exchangers and Related Gaskets

The heat exchanger functions as the heart of the closed cooling system. It allows seawater to cool the engine coolant without direct contact. Diesel Pro Power supplies new and remanufactured cores, gasket kits, and sealing accessories for the Detroit Diesel 6V92.

• Heat Exchanger Core – Manufactured from copper-nickel alloy for superior heat transfer and corrosion resistance.

• Heat Exchanger Gasket Kit – Includes all seals required for tank assembly and end cap installation.

• Individual Gaskets and Seals – For quick replacement of worn components during maintenance.

• Glands and Tank Seals – Ensure a perfect watertight fit and maintain coolant separation.

Routine inspection of the heat exchanger assembly is essential—cleaning and replacing gaskets every two years is recommended to prevent salt buildup or leaks.

Anodes (Zincs) for Corrosion Protection

Marine engines operate in conductive seawater environments, which can cause galvanic corrosion. To counteract this, Detroit Diesel cooling systems use sacrificial zinc anodes. Diesel Pro Power provides a complete range for all cooling components:

• Zinc for Heat Exchangers – Protects internal copper tubes from electrolysis.

• Zinc for Raw Water Pumps – Prevents corrosion in the bronze impeller housing.

• Zinc for Fuel and Oil Coolers – Shields sensitive metal surfaces from saltwater exposure.

Each zinc is threaded with a brass plug and available in various NPT sizes for direct replacement. Regular inspection and replacement of anodes every six months will extend the service life of the entire cooling system.
