It really isnt that hard to do. You can really easily put the standard Fly high 750# sacs
in the back of your boat. Just remove the hard tanks and get some new fittings to connect the bags and you are set. Really pretty easy in terms of installs. That is where I would start. With that much weight in the back you will want to get some more weight up the nose. That Hull Shape (205V) really likes weight up front. You can add the Integrated bow
sac up there and it will tuck away under the seats. Doesn't get you the full 1000 pounds but its out of sight and good to go. With that you essentially just need to reroute your overflow from the KGB ballast (ski locker area) and have that fill the new bag and the take the vent line on that bag to the threw hull/overflow.
All in all its a couple of hours worth of work. And it is by no means rocket science.
I have some directions on a similar boat (current X-2) that will show you how to do it all. Only difference will be where your hose and vent lines are.
Give me a shout if you want more specifics on how it would work.
