What This Part Is Used For
The cylinder head gasket seals the connection between the engine block and cylinder head of a 4-stroke outboard engine.
The gasket helps maintain combustion chamber pressure while separating the engine's cooling water and oil passages.
When a head gasket fails, combustion pressure or engine fluids may leak across sealing surfaces. Depending on the failure location, this can lead to compression loss, overheating, water intrusion, or other engine problems.

Important Fitment Note
Pro Marine 8741 is intended for the earlier Suzuki DF40 and DF50 4-stroke engine families, along with the listed Johnson Evinrude 40-50 HP 4-stroke models.
The Suzuki applications supplied for this gasket cover 1999-2010, depending on the engine model.
This gasket should not be confused with head gaskets used on the later Suzuki DF40A, DF50A, and DF60A engine families.
Suzuki DF40 and DF50 engines are not the same application family as DF40A and DF50A engines. The correct gasket must be selected using the OEM part number and engine identification.
For Johnson and Evinrude applications, verify the exact model number and corresponding BRP OEM gasket number. Not every Johnson or Evinrude 40-50 HP outboard uses this gasket.

Common Symptoms of a Failed Head Gasket
A damaged head gasket can allow combustion pressure, cooling water, or engine oil to leak between internal engine passages.
The following conditions may indicate a cylinder head gasket problem.
- Loss of cylinder compression
- Engine overheating
- Cooling water entering a combustion chamber
- Water contamination in engine oil
- Rough running or misfiring
- Reduced engine performance
- Difficulty starting
- Combustion gases entering the cooling system
- Visible gasket damage during engine disassembly
These symptoms can also be caused by other engine problems. Perform appropriate diagnostic testing before determining that the head gasket requires replacement.
Installation and Service Tips
Replacing a cylinder head gasket requires removal of the cylinder head and inspection of the engine's sealing surfaces. Follow the applicable Suzuki or Johnson Evinrude service manual.
Recommended Installation Practices
- Confirm the original OEM gasket number.
- Verify the engine model and applicable year.
- Allow the engine to cool before disassembly.
- Remove the cylinder head following the service manual.
- Inspect the cylinder head and block sealing surfaces.
- Check for warpage, corrosion, cracks, or damage.
- Remove old gasket material without damaging sealing surfaces.
- Keep debris out of the cylinders and internal passages.
- Install the replacement gasket in the correct orientation.
- Follow the specified cylinder head fastener tightening sequence.
- Use the required fastener tightening specifications.
- Replace other gaskets and seals when required by the repair procedure.
- Inspect the cooling system for conditions that may have caused the original failure.
- Check engine operation and cooling performance after reassembly.
Important Cylinder Head Installation Warning
Correct gasket installation requires proper surface preparation, cylinder head inspection, and the correct fastener tightening procedure.
Do not install a new head gasket over warped, cracked, or improperly prepared sealing surfaces. Improper installation can result in compression loss, cooling water leakage, overheating, and engine damage.
