I have an 06 polarkraft 1910 with a 200 hp suzuki 4-stroke my current prop is a 3x16x17, this gets me 47 to 48mph but I need to watch my rpm because it can go over 6000 rpm, it is in the 3rd hole down from top. When I first got it, it had a 3x16x18.5 I believe, it got 50mph but only around 5200 rpm, so I changed to the current set up. I am concerned with my rpm's and mph any recomendations. thank you

Thats quite a jump in rpms between the two props has either of them been repaired? They shouldn't be that far apart. Their should be about 300 rpms difference.

No both were brand new, thats why I was a little surprised it went up that high

I have a Pro-V with a Suzuki and can run it in the first or second hole down. With 1 1/2" change, I get 300-400 difference in rpm. You might try moving the motor up one or two and try the 18 1/2" again?
