Good Grief

I have a 98, 290 sundancer with Mirage 15.75x15 props (48-19841 15P & 48-19838 15P) purchased it that way. Not long ago I read a prop thread where an individual calculated what the effect of changing props would be.
SeaRay recommends 13.75x21 props.
I'm trying to determine the "hypothetical" difference prior to investing in changing the props.:huh:
The boat has twin 4.3l mercruiser (190hp) and Alpha 1 Gen2 O/D's.
There is a little inaccuracy in the actual vs. indicated RPM. When surveyed there was 50 RPM difference between actual and indicated at 4600RPM. When accelerating to get on plane I have seen up to 5000 RPM and immidiately backed off.
Thanks in advance!:smt038
