Parts for Detroit Diesel 16V71 Non-Turbo – Marine Water Pump Section

The Detroit Diesel 16V71 Non-Turbo is a workhorse in the marine industry, known for its durability, reliability, and raw mechanical power. Like all marine engines, its cooling system plays a vital role in ensuring long service life and consistent performance. The raw water (or sea water) pump is the heart of that cooling system, circulating seawater through the engine’s heat exchangers and coolers. Without a properly functioning water pump, overheating, reduced performance, and costly downtime become unavoidable.

At Diesel Pro Power, we specialize in aftermarket solutions for Detroit Diesel engines, including the 16V71 Non-Turbo. Below is a complete catalog of water pumps, impellers, repair kits, gaskets, seals, zincs, hoses, and supporting cooling system components. Every product is designed to meet or exceed marine-grade standards, with worldwide shipping to over 180 countries and trusted support from our team of heavy-duty engine specialists.

Repair Kits and Replacement Components

Major Repair Kits

Designed for Detroit Diesel marine pumps, these kits include shafts, bearings, and seals required for a complete overhaul. Recommended when pumps show signs of leakage, worn shafts, or decreased impeller efficiency.

Impellers for 16V71 Marine Water Pumps

• 3 ½” Impeller – Features 12 blades and a double-flat drive, engineered for the standard 16V71 Non-Turbo water pump.

• 4 ½” Impeller – Larger size for high-capacity pumps, optimized for vessels requiring greater seawater flow.

Both impeller types are made from durable marine bronze and rubber compounds, designed to resist saltwater corrosion and maintain flexibility under load.

Impeller Puller Tool

Specialized tool for removing impellers without damaging the pump housing. Essential for routine maintenance and a must-have in any marine engineer’s toolkit.

Gaskets and Seals

A wide range of gaskets is available for the Detroit Diesel 16V71 raw water pump system:

• Mounting Gaskets – Ensure a proper seal between the pump and engine block.

• Cover Plate Gaskets – Prevent leaks at the impeller access cover.

• Inlet & Outlet Gaskets – Each pump uses two, providing secure water passage.

• Plate Gaskets – For securing the pump assembly.

• Thermostat Seals – Designed for both 160° and 170° thermostats used in V71 and V92 applications.

High-quality seals and gaskets are crucial to preventing seawater leaks that could damage surrounding components or compromise pump efficiency.

Thermostats for Detroit Diesel V71 Cooling Systems

The cooling system relies not only on the raw water pump but also on thermostats to regulate engine temperature. Diesel Pro Power offers thermostats for Detroit Diesel 71 and 92 Series engines in both 160° and 170° options. Each thermostat comes with corresponding seals to ensure leak-free operation.

Heat Exchangers and Cooling System Support

For Detroit Diesel 12V71 and 16V71 applications, we supply complete heat exchangers, rebuilt exchanger cores, and gasket kits. These components are critical for efficient transfer of heat between seawater and the engine’s closed cooling system. Available both as standalone tanks and full rebuilds, these exchangers help extend the life of your engine and improve performance.

Zinc Anodes – Protecting Against Corrosion

Zinc anodes are sacrificial components designed to protect marine cooling systems from electrolysis and saltwater corrosion. We offer a complete selection of zincs for Detroit Diesel heat exchangers, oil coolers, and fuel coolers, with sizes ranging from 1/8” to ¾” NPT fittings. Regular replacement of zinc anodes ensures the longevity of your pump and cooling system by absorbing corrosive elements before they can damage critical engine parts.

Hoses, Clamps, and Accessories

Silicone Coolant Hoses

Available in a wide range of diameters from 1” to 4”, these heavy-duty hoses are designed for long service life in marine environments. Silicone construction resists heat, salt, and vibration better than traditional rubber hoses.

Hose Clamps

A variety of stainless-steel clamps designed to secure coolant and seawater hoses. Offered in multiple sizes to fit the full range of hose diameters used in Detroit Diesel marine engines.

Couplings and Bearings

• Accessory Drive Coupling (21 teeth) – Transfers power reliably from engine to pump.

• Marine Pump Bearings – Replacement ball bearings ensure smooth impeller rotation under load.
