3862482 — Sea Water Pump 21214599 3812693 3862482 For Volvo Penta Engine 3.0 4.3 5.0 5.7

This sea water pump is integral to the engine's cooling system, circulating raw water through the heat exchanger to dissipate engine heat. Manufactured from corrosion-resistant materials, it provides robust performance and longevity compared to a pump with a worn impeller or leaking seal. Operators may notice the engine temperature gauge rising above normal, audible noises from the pump area, or visible water leaks when this pump begins to fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early signs of a failing sea water pump include the engine temperature gauge reading higher than normal or unusual noises like grinding or whining from the pump. If the problem progresses, the engine can overheat, potentially causing severe damage to internal components. Continued operation without adequate cooling risks significant and costly repairs to the engine block and cylinder head.

Installation Tip

Before installing, lubricate the new impeller with a marine-grade lubricant to ease installation and prevent initial damage. Ensure the drive belt is properly aligned and tensioned after the pump is secured.

Service Note

Inspect the engine's heat exchanger and hoses for any signs of blockage or deterioration when replacing the sea water pump.
