Installation Notes

Always consult your engine's official service manual before starting work. The following are general, non-model-specific guidelines:

  1. Ensure the engine is off, cool, and disconnected from the power source.
  2. Access the engine's exhaust housing assembly, which may require removing the lower unit or other components.
  3. Carefully unbolt and separate the components sealed by the old gasket.
  4. Remove the old exhaust housing gasket completely.
  5. Thoroughly clean both mating surfaces, removing any old gasket material, corrosion, or debris.
  6. Position the new gasket correctly onto the clean surface, ensuring all holes align.
  7. Reassemble the exhaust housing components, tightening bolts to the manufacturer's specified torque in the correct sequence.
  8. Reconnect the power source and test the engine for exhaust leaks at the seal.

Troubleshooting & FAQ

How do I know if this gasket fits my OMC engine?

Since specific model compatibility data is limited, the most reliable method is to match the part number 324717 against the number specified in your engine's service manual or parts diagram. Verifying the visual match with your old part is also recommended.

What does "new old stock" mean?

"New old stock" (NOS) means the part is new and has never been installed, but it may have been in storage for an extended period. As a result, it might not come in the original factory packaging but is otherwise in excellent, ready-to-use condition.

What are the signs of a failed exhaust housing gasket?

Common symptoms of a bad gasket include an audible exhaust leak (a hissing or ticking sound from the engine), visible fumes escaping from the housing seams, decreased engine performance, or water entering the exhaust system.

Should I use sealant with this gasket?

Most gaskets of this type are designed for a dry installation. However, we always recommend consulting your engine's official service manual for specific instructions, as some applications may call for a light application of a specific sealant.
