V20 with Black Max 150???

Thanks for the advice guys. The cavitation plate is level with the very bottom of the transom, it looks right to me. I have to check and make sure the tach is set up right, the boat used to have an Evinrude, not it's a Merc, maybe the tach is wrong? I do think the prop is a bit too small, just because of the way the boat comes out of the water like a rocket. I need to try and find a Mirage Plus 19 to try out.
