Detroit Diesel 16V149 Turbo Marine Water Pump - Aftermarket

Detroit Diesel 16V149 Turbo – Marine Raw Water Pump & Cooling System Components

When operating a Detroit Diesel 16V149 turbocharged marine engine, the raw water pump and associated cooling components are critical for reliable performance. The raw water pump draws seawater into the cooling system, regulating temperatures under heavy load conditions and protecting the engine from overheating. Below is a complete catalog of marine water pump parts, repair kits, impellers, gaskets, seals, hoses, and related accessories specifically for the Detroit Diesel 16V149 turbo application.

Marine Raw Water Pump for 16V149 Turbo Engines
