Intermittent RPM's

[Scuda11]

Hi all, I have said in here before I have a prob with WOT rpm's. I fig it is my prop, however, my engine is running great and I noticed today that I jump about 300-400 rpm's at WOT. <br /><br />Could I have a slipped prop, if so, how do I check for it??<br /><br />Thanks as always guys.<br />Scott
