What RPM and speed should I expect?

[Glastron175]

I just tuned my Glastron 175 SF with a 3.0L engine (3.0GSMEFS). I also have a new 19 pitch, 3 blade prop. What max RPM and WOT speed should I get. I am getting 4600 RPM and 36 MPH with two on board.

By the way, my prop is a 14.5 inch prop.

Sorry, just realized I am in the wrong forum. I'll repost it correctly.
