Important – Water Jacket Cover Gasket
This is a water jacket cover cylinder head gasket.
It is not the main cylinder head gasket.
Please check the position of the gasket and your original OMC part number before ordering.
Important – Please Check Compatibility
Please do not order by horsepower or appearance alone.
Johnson and Evinrude used different gaskets across engines with the same horsepower.
Before purchasing, please check:
- Engine horsepower
- Exact engine model
- Model year
- Engine model/serial number
- Existing gasket
- Original OMC part number
If the gasket looks the same as yours, this does not always mean it is the correct gasket for your outboard.
If you are unsure, please send us your engine model number before purchasing and our technical team will be happy to check compatibility.
