You can loosen those v-clamp joints in a few minutes. All it takes is a 12 mm wrench. Then you can inspect the dry elbow and the water injection elbow. Even though you can see rust spots on the outside, these were left by the cast iron dies when they were cast. They are cast stainless steel and will last a long time.

When you have them off, take a good look at the exhaust turbo outlet. The inside of the housing should be smooth with a light soot coating.

Any roughness indicates corrosion from sea water backing up.
