🔌 Function

The engine-driven flexible-impeller seawater pump draws raw water through the vessel's intake and strainer, then circulates it through the heat exchanger, charge-air cooler, exhaust mixer and other seawater-cooled components. Adequate flow is essential for controlling engine and exhaust temperatures.

Common signs of failure:

• Engine or exhaust temperature rises above normal

• Weak or absent seawater discharge at the exhaust outlet

• Impeller blades are cracked, missing, swollen or permanently set

• Water leaks from the pump cover, shaft seal, drain hole or mounting flange

• Bearing noise, shaft play or a seized pump drive

📦 Condition

• New aftermarket replacement seawater pump

• Brand new

• Supplied in original or equivalent packaging
