Pro Marine 246-1 Cylinder Head Gasket
We also stock the Pro Marine 246-1 version of this Mercury / Mariner 2.4L V6 head gasket. It replaces the same Mercury OEM numbers and fits the same application family.
What This Gasket Is Used For
A cylinder head gasket seals the joint between the engine block and cylinder head. It must contain combustion pressure while also sealing cooling passages around the cylinders.
On older Mercury and Mariner V6 2.4L engines, head gaskets are commonly replaced during powerhead rebuilds, cylinder head removal, overheating repairs, or diagnosis of water intrusion and compression loss.
Installation Notes
- Clean and inspect the cylinder head and block sealing surfaces before assembly
- Check for corrosion, pitting, and warpage before installing a new gasket
- Use the correct Mercury service manual torque sequence and torque values
- Inspect head bolts and replace any damaged or questionable hardware
- Each V6 powerhead uses one head gasket per cylinder head
