Volvo engine RPM

ahmet kipcak

I would like to say hello to everybody and thanks for very helpful info sharing here.
I bought my Amel 1999 six mounts ago, My engine Volvo TMD 22, 1999, 2500hours.
I would like to learn what average engine rpm should I see with max power with clean auto prop propeller.
When I was sailing with engine off, still I observed slow turn in drive shaft, is this normal for auto prop properler.

Thanks for your help
