Too much prop?

Hello:
I am hoping that others with a C85 can answer this. I have a Sensenich metal prop model 76AK-2-42. Wide open throttle in level flight I can only get about 2375 rpm doing about 90 mph. The tach was just calibrated.

Can others tell me if they can red line (2575) their engine with this prop?

Thanks.
