How to inspect and tell if your manifolds and risers need your attention, or to be changed.
Without taking apart:
1/ check for corrosion on the outside
2/ check for leaks around gaskets from the outside
3/ check oil level
4/ check oil color
5/ check temperature
Taken apart:
1/ check water passages
2/ check for signs of corrosion inside exhaust
Tips:
1/ use only high quality risers and manifolds
2/ perform all checks on regular basis
3/ flush as much as you can whenever you can

Thank you so much Professor AK, Did you realize that your dog was trying to inform you at 3:26 that you should not have waited 16 years to replace your manifold.

This is a dry joint exhaust he is showing. They last considerably longer than five years, especially if you flush your engines after each use.

Not in saltwater

You got that right. I was trying to figure out how long these dry joint exhaust systems last and couldn't find any definitive answer anywhere so I contacted the inventors of it at "Performance Product Technologies". They own the patent on the dry joint system. I talked to the actual man who invented it (name escapes me) and I told him my set up. I run in a mix of salt, brackish, and fresh water and that I diligently flush after every use. He said he would not be surprised if they lasted longer than 20 years (but understandably did not want to imply a warranty for that long or anything). My boat is a 2005 and still has the original dry joint system on it and it runs as good as ever.

Lol "without taking it apart?" You have the manifold set on your table? You will need to remove the manifolds to inspect them!! If they are removed, throw them away and buy new ones. Saltwater lasts only 5 years and fresh 10
