Re: overpropped vs underpropped

I have a Yanmar 3JH5CE with SD50 saildrive. How do I know what RPM should be at WOT. The only figures I can find is that the manufacturer quotes a maximum output figure at the crankshaft which is 39hp @ 3,000 RPM. With the original fixed prop, I can get around 3,200 RPM. What does this mean in terms of being over- or under-propped?
Many thanks
