17/15*5000= 5600-5700 RPM. A change to a 15 P prop is probably a good starting point, plus you will probably make a tiny bit more power at that RPM, so you might pull a bit more than 5700 at WOT, if everything is just right. Holeshot should be lots better, I would think. I did this same think on my F100 on a 20 and it is much better. Only about 1/2 to 1 knot faster, but much better acceleration with the 15P. I pull about 28 knots that way with a slightly lighter boat and less power (20 gallon tank, no frills).
