I'm looking at my performance report from Fountain, stock with a XR there is a "19" in the blank after X-demention. I'm assuming that's 19 centimeters if that isn't a typo. That would mean about 7 1/2 inches stock minus 2 inches for my current setup. Does that sound right?

19" should be the distance from the bottom of the hull to the crank centerline i.e your X dimension. With the stock bravo lower your propshaft should be around 3" below the bottom of the hull.
With the -2 you must be around 1" below. Try to space down 1".

Gotcha, I guess I was under the wrong impression of what the x dimension was.
