Thanks Tony for the response- we won’t worry about the CCP. Aftercooler housings were no good in 2018 and replaced with new and greased. We added freshwater flush at that time. 

Just pulled the cores after five years and they came apart easily and look serviceable, pics attached.

I have a 1999 32+2 (Yanmar 6LY, but similar enough constraints) and had Tony look at the exhaust when I bought the boat. I replaced the exhaust elbow  with a stainless version from Seaboard (they welded on a temp sensor to alarm a loss of raw water flow) and installed a fresh water flush system. The injection height above waterline is more than adequate. 

I was advised that while the elbow wouldn’t fully self drain the fact that it is heavy stainless and doesn’t have salt water sitting in it would result in a very long life.

Got it, thanks all.

Thanks Tony. Yes, low annual hour vessel.

Top end speed is not a concern, and it is currently operating below the prop demand curve for both the 550@3300 and 480@3000 ratings.

We will investigate the cost of re-rating as well as prop modifications.
