Important – Please Check Compatibility
Please do not order by horsepower or appearance alone.
Johnson and Evinrude produced different engine versions over the years, and not every 5–8 HP engine uses the same cylinder head gasket.
Before ordering, please check:
- Engine horsepower
- Engine model
- Model year
- Engine serial number
- Existing gasket
- Original 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 and serial number before purchasing and our technical team will be happy to check compatibility.
