Another Prop ?

I think you'll be somewhere in the in mid 40's with a 17 pitch. Just depends on how fast that motor will spin the prop. You want to make sure you prop that motor so it can turn at least 5500rpm at WOT. Also . . . make sure that the cavitation plate lines up about an 1" or 2" above the bottom of your hull. That makes a big difference in LU drag and the props ability to ventilate.
