Getting to the 5 year mark where I am going to be changing the manifolds. As we all know with the 8.1s its a few boat dollars and the question whether to inspect the elbows and not replace due to them being Stainless comes up. I asked a very reputable mechanic and he said to replace the elbows with the manifolds as the weld at the plate could fail due to heat and create salt water to leak back to the engine. I see numerous posts where the elbows are just inspected and placed back on motor. My gut is saying to just replace but wanted to get some more feedback as other mechanics have told me they are good for a few more more years.
