Detroit Diesel 6V71 Turbo Marine Water Pump and Cooling System Parts Catalog

Overview of the Detroit Diesel 6V71 Turbo Marine Engine Cooling System

The Detroit Diesel 6V71 Turbo engine, part of the legendary Series 71 family, is renowned for its durability and performance in demanding marine environments. Used extensively in commercial vessels, fishing boats, workboats, and military craft, this two-stroke V6 turbocharged engine requires a robust and efficient cooling system to maintain peak operation.

Marine engines face continuous exposure to saltwater, high ambient temperatures, and long operating hours, making the raw water pump and associated cooling components vital for reliability. The marine water pump in the 6V71 Turbo engine draws seawater into the cooling circuit, regulating engine temperature and preventing overheating.

At Diesel Pro Power, we provide a complete catalog of marine water pump components, rebuild kits, impellers, gaskets, thermostats, seals, hoses, and zincs—all designed to meet or exceed OEM standards for Detroit Diesel 6V71 Turbo engines. With over 40,000 satisfied customers worldwide, Diesel Pro Power is the trusted global source for marine parts shipped fast and backed by expert support.
