Troubleshooting & FAQ
How do I confirm this gasket fits my engine?
This gasket is designed for Bombardier/OMC 60° V4 engines (including Evinrude and Johnson) from 1988 and newer. The most reliable way to confirm fitment is by matching your old part's number to the OEM reference: 344386.
What are the signs of a failed exhaust housing gasket?
Common symptoms include water in the cylinders, engine overheating, poor performance or rough idling, and visible water or exhaust leaks between the powerhead and the drive shaft housing.
When should this gasket be replaced?
This gasket must be replaced whenever the powerhead is removed from the exhaust housing for service. It is a single-use seal and should not be reused, as it crushes to create a seal and will not seal properly a second time.
Is any sealant required during installation?
Generally, this type of gasket is installed dry. Applying sealants can interfere with proper seating and torquing. Always consult your official service manual for model-specific recommendations.
