Important – Water Jacket Cover Gasket
This product is the water jacket cover gasket, sometimes searched for as a cylinder head cover / water jacket gasket.
Please make sure this is the gasket you require before ordering.
Important – Please Check Compatibility
Please do not order by horsepower or appearance alone.
Johnson and Evinrude produced different engine configurations across these years.
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.
