🔌 Function

Forms the sealed pumping chamber in which the flexible impeller draws seawater from the intake and delivers it through the heat exchanger and exhaust-cooling circuit.

⚠️ Common Signs of Failure

• Scoring, corrosion or cavitation damage inside the chamber
• Reduced seawater flow despite a new impeller
• Persistent leakage from worn seal or bearing bores
• Damaged cover threads or distorted sealing face
• Repeated impeller damage caused by rough or worn housing surfaces

🛠️ Service Notes

• This is the housing for the earlier-style D6 seawater pump design (complete pump 21380890, previously 3589907 and 3584063) - later D6 pumps use a different housing, so confirm your pump generation before ordering
• At 2.917 kg, renew the seals and cover gasket when the housing is fitted, and inspect the shaft, cam and wear plate that run in it for the scoring that damaged the old one
