Installation Guide

  1. Safety First: Ensure the engine is completely cool and disconnect the battery terminals to prevent accidental starting.
  2. Drain Coolant: If your system is fresh-water cooled, drain the coolant from the exhaust manifold to avoid spills.
  3. Remove Hoses: Carefully disconnect any cooling hoses attached to the exhaust elbow or riser.
  4. Unbolt Elbow/Riser: Loosen and remove the bolts securing the exhaust elbow to the manifold. You may need a breaker bar for stubborn bolts.
  5. Remove Old Gasket: Lift the elbow off and set it aside. Carefully remove the old gasket.
  6. Clean Surfaces: Thoroughly clean both mating surfaces on the manifold and the elbow. Use a gasket scraper or wire brush to remove all old gasket material and corrosion.
  7. Position New Gasket: Place the new gasket onto the manifold, ensuring a correct and flush alignment with the bolt holes.
  8. Reinstall Elbow: Carefully place the elbow back onto the gasket and thread the bolts by hand.
  9. Torque Bolts: Tighten the bolts in a crisscross pattern to the manufacturer's recommended torque specification to ensure an even seal.
  10. Final Connections: Reattach all cooling hoses and clamps. Refill coolant if necessary.
  11. Check for Leaks: Reconnect the battery. Start the engine and let it run for a few minutes while carefully checking for any exhaust or water leaks around the new gasket.

Troubleshooting & FAQ

How do I confirm this gasket fits my specific OMC or Volvo Penta engine?
The most reliable method is to check your engine's model and year against the detailed compatibility tables provided on this page. You can also compare the OEM part number listed in your service manual (3850495 or 908013) with our cross-reference list.

What are the common signs of a failing exhaust elbow gasket?
Symptoms of a bad gasket include visible water leaks around the joint between the manifold and elbow, an overheating engine, steam or water vapor coming from the engine compartment, or a noticeable drop in engine performance.

It is recommended to replace exhaust elbow and riser gaskets during routine exhaust system maintenance, typically every 3-5 years in saltwater environments or when the components are removed for inspection or other service.
