🔌 Function

Transfers heat from the engine coolant into the raw seawater passing through it.

⚠️ Common Signs of Failure

• Overheating under load with the raw water pump working correctly
• Coolant loss into the seawater side, or seawater in the coolant
• Tube stack fouled with scale, silt or shed impeller vanes
• External corrosion at the end covers
• Weeping at the end seals

🛠️ Service Notes

• Confirm the engine serial number before ordering, since the configuration varies between builds
• Shed impeller vanes collect here - check the tube stack whenever a seawater pump has failed
• At 60 kg this needs lifting equipment, and the end seals should be renewed on reassembly
