Scott,
I do not think you'd be too happy with the Stiletto 13.25" x 15". I tried that first (carry-over from when the motor was mounted on my 15' Sport CC), and it was very sluggish, even with just me. I was not able to get to WOT, only about 5400RPM.

The Stiletto 13.25" x 13" is much more responsive, and gets on plane with 4 & 23gals of gas. I haven't had the opportunity to load it more heavily. However, with just 1 or 2 people, it will rev-limit the motor. I can still get to about 36mph.

The Yamaha 14" pitch propeller you referenced might be ideal for the lightly loaded boat, if that's what you'd like to optimize for.
