The best bet here for your options listed would be the 13.25 x 17 as you are only increasing diameter by 1/4" (-100 rpms)and reducing pitch by 2 inches (+250 - 400 rpms) which would be an overall gain of about 300 rpms.
If I were to make a suggestion, I would recommend going to a 15 pitch to get your rpms under light load right at 5300. That way when you load down, you will be right in the middle of the rpm range from 4700 up to 5300.
You will lose speed no matter what prop you go to in your situation, but your hole shot will be rock solid. In most cases, the power at the low end is a much better feature to have as you are able to get your boat out of the water on and plane quicker and if you are in larger waves, it gives you the power to maneuver better.
