0389731 Leaf Plate Assembly – Johnson / Evinrude / OMC

The 0389731 Leaf Plate Assembly (often listed as part number 389731) is a genuine OEM component for many classic Johnson and Evinrude outboard engines produced under the Outboard Marine Corporation (OMC) umbrella.

This assembly fits within the reed-box or timing assembly area and provides the mounting plate or “leaf” structure that supports surrounding components and maintains proper alignment. When the original leaf plate becomes worn, bent or corroded, you may see poor reed operation, engine mis-timing or reduced performance. By installing this 0389731 Leaf Plate Assembly you restore correct mounting geometry, reinforce structural integrity and ensure reliable engine behaviour under load. Buyers report seeing it listed for vintage 60 HP-75 HP Johnson/Evinrude units (1979-2006) under cross reference numbers like 0389731 or 389731.
Select this part when you're performing a rebuild or replacing ageing powerhead-internal components. Use correct torque, clean mating surfaces and verify alignment after installation to get the best results.
