## 🔌 Function

Restricts and directs the movement of oil inside the engine, keeping it where the pickup can reach it as the boat pitches and rolls.

## ⚠️ Common Signs of Failure

-   Oil pressure dipping when the boat pitches, rolls or turns hard
-   Plate found cracked, distorted or with fasteners missing
-   Fretting or contact marks where the plate has been moving against something
-   Debris in the sump from a plate that has broken up
-   Oil surge noise or aeration under load

## 🛠️ Service Notes

-   Check that every fixing is present and secure — a loose baffle plate can break up and reach the oil pickup
-   If your records show 846742 or 858069, this is the number that now covers both
