I would say you could potentially move it up 2 holes, then drop down in pitch to a 17. The move up 2 holes will get you roughly 200 rpms, then the drop in pitch by 2 inches will get you another 400 RPMs given you are getting the same prop brand and model.
Just curious...are you running a steel prop or aluminum?
Your motor is right on the cusp of seeing nice improvements going steel. Steel will flex less, the blades are thinner and are able to be cast into more aggressive designs. Also, you could also try a good 3 blade that has decent trailing edge cupping (michigan ballistic would be a decent example) to help lift the stern and keep your pitch a little higher as well.
Lots of possible options and if you post your numbers as you try things, it could be very interesting to see what results you come out with.
