## ⚙️ Key Features

-   Seawater pipe from the Cooling System group
-   1.888 kg
-   Listed for seven D series engine applications
-   Corrodes from the inside - inspect the bore rather than the outside

## 🔌 Function

Carries raw seawater through the cooling circuit between the pump, the heat exchangers and the discharge, keeping the flow that takes engine heat overboard.

## ⚠️ Common Signs of Failure

-   Seawater dripping or spraying in the engine space
-   Salt crusting or green staining at a joint or along the pipe
-   Overheating or high temperature under load as flow falls
-   White or green scale and heavy corrosion found inside the bore
-   Pinholes through the wall, or a wall so thinned it dents under thumb pressure

## 🛠️ Service Notes

-   Judge the pipe from the inside - a seawater pipe can look sound externally and be almost through from the bore
-   Renew the seals, gaskets and hose clips at every joint disturbed, and check the anodes in the raw water circuit at the same time
-   Close the seacock before opening the circuit and check for leaks with the boat afloat before leaving it
