It ran 50mph on a pair of 45mm 1.4 pitch cnc X props , ran 57mph a pair of 48mm 1.4 pitch X props still not there yet and starting to get warm on the 48mm. thought about trying a 45mm 1.9 pitch X prop need to get this boat in the 60's on 4s any suggestions ?

45/1.9 will give you 27% more travel over the 48/1.4. That's going to translate into even more heat I would think.

Why the quest for 60 Chris?

I'm not sure you're going to get there with the stock motors. You should check with Stancomb. He's the expert.
