The big advantage of the dry risers is that no water will leak into engine when/not if/ the wet riser corrodes through. They are also self-draining, i.e. saltwater will drain from the mixer when the engine is shut down. In the wet riser saltwater fills the riser all the time.

I agree the risers are a routine maintenance item. But they are now more difficult to find and are getting very expensive. They have gone from $400 each to $1500+ each the last five years. And you need four of them in a twin engine setup.
