if it is the stock prop, then you have the 13.7x17 prop, which is not good for ballast. MC switched to the 14.25x14.5 OJ in 07 or 08 and switched to a different prop recently (15.?x??). both oj and acme make good props for ballast boats and could put you on what you need. Personally, I run the 14.25x14.5 (stock with 08 x2)with over 2000 lbs and it does good with ballast without raising the rpms too much at cruising speeds. The 14.25x14 would even do better with ballast but it would raise the rpms more. A different boat but a good comparasin is my 06 x1, I ran both the 13.7x17 and the 14.25x14.5 and it was a huge difference.
