I have the same boat that you do and would like to know if the 750# would fit. I am running the 400# V-drive sacs and they are about an inch from the sunpad at the stern. I had to cut a few bolts that were really long as well as removing the panel that covers the filler kneck to get enough clearance. I wish I had the 750# for wakesurfing, but the 400s do great for wakeboarding!!
