I am running a Raylar HO525 so probably close in HP with a stock X-dimension with a -2 imco. I spin a 27 Hydromotive Qiv to the stock limiter. I just bought a 28 as they make every inch in that prop but have not tried it yet. I couldn't decide between the 28 and the 29 but thought I would try the 28 first. I am currently running a labbed 29 mirage to about 5150 RPM. I like the way the four blades handle on my boat better, a little slower than the mirage but more stable. I prefered the Hydro over the Bravo 1, a little better handling and more speed for at the same RPM. Hopefully the 28 works well. Hope to try it soon!
