🔌 Function

Carries sea water from the drive unit intake to the sea water pump.

⚠️ Common Signs of Failure

• Poor or no sea water flow at the exhaust outlet
• Air drawn in on the suction side, so the pump loses its water
• Corrosion pitting or perforation of the tube
• Salt crust or weeping at a connection
• Impeller failure caused by a restriction upstream

🛠️ Service Notes

• Seawater pipe 840802 at 0.141 kg carries the same routing note between the drive unit and the sea water pump, so the two are only 6 grams apart and must be told apart by part number and by where they sit
• A leak on the suction side stops the pump priming, so check every joint on this run when cooling water is lost
• Check the pump impeller after any restriction or dry running
