1617 or 1433 are awesome props. I really think a 14x12 is going to be overkill and probably max speed of about 34 mph. I run 3k lbs of ballast in mine with the 1617 and it is perfect.
1235 will cause prop burn. I know people that run it anyway though. I'm sure it would be fine in a pinch.
Pulled my brother on a slalom this weekend. 36 mph was just shy of 4900 rpm with the stock 1579 prop (I switched back to stock because he was going to be in town). The boat will go faster than that, but not with a slalom skier back there who pulls really hard. So, the 1617 would be well over 5k rpm.
If you're wanting to ski at all, I would recommend the 1433. It will get the boat up no problem with the amount of ballast you're running.
