I just got the tach working on my 1987 90HP 3 cylinder Merc. I was wondering what RPM I should expect at WOT.

I'm reading 750 rpm at idle and I got 6500rpm at WOT, this seems a bit high, I backed it off to 5,000 rpm right away. I have the 21 pitch prop that was on the engine when I bought the boat, it also came with a 24 pitch prop.
