I had the heat exchange removed and serviced. It was semi
complicated proedure. An owner could do it if he was familiar with
the process. If you are not mechanically inclined I would not
attempt it. There are seals to replace and most likely the heat
exchange will be in bad shape. I also had the turbo removed and
serviced. Check your muffler for rust.
Hope this helps.

but unfortunately I have deleted the relevant email. I now wantto do the
same. Could he tell me if he did this himself and if so what isinvolved in
extracting the insert? It looks as though , once the pipework hasbeen
disconnected, four bolts holding a plate are extracted and thepipes holdng
the seawater ( what I call the ¨insert¨) are simply pulled forwardand out
of the exchanger. Is it this simple or do you also have remove theturbo to
get access? Did you have to replace any seals?Azen, SM
