TClay,
If your max rpm is 6400, a drop in pitch will definitely be in order. With the height change, you would gain about 300, then going down in pitch to a 17, you will gain another 300 or so as well.. this rules out a tach being off and definitely puts it at a pitch issue.
If you have access to any friends with props to try or go to eBay and see what you can find, you'll see a magnificent increase in performance going down in pitch and up in height.
Running some quick numbers on a 17 pitch, 6300 rpm and 12% slip theoretically you should be at 43 mph. You get to 41 or 42 you are sitting well...and... you will have much better holeshot... the merc 115 is not fast out of the hole to begin with (from my experience with them), so this will be a great step up with it as well...
Steve.
