1999 90hp Johnson RPM's

[Sea Hunt Triton 172]

I have a 1999 90hp Johnson on a 17' Seahunt Center Console. What RPM's should i be turning at WOT? Not sure what the prop is and I'm guessing this will have an impact on the rpm's but if I am getting what is considered normal then can I assume I have the correct prop?

I do not have the exact specs, however, 4500-5500 is the usual range. A 2" change in pitch will alter the WOT RPMs by 400
