## 🔌 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
