⚙️ Key Features

• Intake to sea water pump
• 0.771 kg
• 14 applications across six series
• Suction-side raw water hose
• Quantity varies by assembly, most commonly one

🔌 Function

Carries raw water from the intake to the sea water pump, taking the full suction of the pump without collapsing.

⚠️ Common Signs of Failure

• Hose collapsing or flattening as revs rise, with raw water flow falling off
• Air being drawn in at a clip, showing as reduced flow or a spitting exhaust
• Hose gone hard and cracked, or soft and delaminating at the bore
• Salt crust, white staining or a drip trail at a joint
• Inner reinforcement broken down so the hose feels floppy along its length

🛠️ Service Notes

• This is on the suction side, so an air leak here shows up as poor cooling rather than as a visible drip - check the clips and the stub condition carefully
• A hose that collapses under suction has lost its reinforcement and must be renewed even if it is not leaking
• Renew the clips with the hose and check the seacock and strainer while the line is open

📦 Condition
