First off, your dealer is smoking some serious crack if he wants to charge you $570 for a 13.7x17 prop. You can get them for $412 at: http://www.propellersonline.com/skiboat.php?PHPSESSID=d5701756bdb96e93b1a836da3325 6f26
I cannot say for sure how the 14.25x14.5 will work on your boat, but I just bought a similar prop (14.25x14) for my Supra and I am kicking myself for suffering the last two years with the stock prop (14x18) I was using. With the new prop it's like driving a different boat. The hole shot is unreal. It's like there's no ballast in the boat, despite the 2400 lbs I'm riding with. Also, with the new prop my boat holds speed so much better. I was without my perfect pass this past weekend (sent off for repair) and with the new prop I had no trouble at all holding speed on my own.
Contact Eric and OJ and he will tell you which prop you need for the ballast you are running. If you do go with the lower pitch prop I believe you can get it for $475 at the same link above. Also, Karl at www.boarditup.com
has decent prices as well. However, you may find the best deal at skiertoskier.com
