Great write up and good information for sure. Props make all the difference in the world. Especially the faster you go. Even the smallest of changes can drastically change how your boat performs and handles. So I'm not surprised with your results. Strange thing is, even with identical (or what you think are identical) boats, you can have different props act differently. No two boats are the same. So your results may not work for the next guy with your hull and power, but it should at least get him close. Good info, thanks for posting it up!
