Intercooler accessibility. MS 350/390

I have a 1999 Mainship 350 with twin Yanmar 4LHA-STE turbo diesels... The - STP is a virtually identical engine in the later built 390s.
Has any one out there ever removed the starboard engine aftercooler for cleaning or repair? Seems to be near impossible to access from the side or top! I had a much experienced mechanic give up on removal . Other than moving the engine off of it's mounts or cutting up the salon sole above the engine is there a way to get it done?
