🔌 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
