Sorry, I don’t have the same engine but hopefully someone else will answer that question for you.
In general, if your engine is reaching your normal full throttle loaded rpm in neutral but you are 700 short under load of what is normal, either the load is higher than it used to be or the power output has dropped for some reason. You indicate that the prop is perfectly clean but perhaps it is not auto pitching properly for some reason? There has been a lot of discussion on the Auto-prop (which I do not have on my boat) on the forum that you could bring up by searching.
Best of luck and I hope that you get more help with this problem,
