I am about stumped, other than normal servicing no other work has been
done
to the motor which might cause this, I havent played with the injectors or
pump settings etc. I am open to any suggestions.

There was a discussion about something similar (though not exactly the same)
in Practical Boat Owner no 446 February this year in "Ask The Experts" on
page 69. I don't entirely understand your problem and I similarly don't
entirely understand the article but there are enough points of similarity to
lead me to point to it. The heading was "Yanmar engine revs"
