Ballast Bag Question

Hey I've noticed alot of people are running with a 750lbs sac in their back locker. I'm only running 350 now but would like to get that number up to around 500-550. No way my back locker is big enough to fit a 750 sac but it's definitely got some room up above and on the sides, just not length wise and I really can't find one that has the right dimensions. So I guess my questions is, can I just get a 750lbs sac, shove it in the back locker, fill it, and let it mold/conform to the space provided? Any structural issues to either the boat or sac I need to be worried about? Kind of concerned that this really wouldn't matter with a sac that's slightly to big, but a 750 sac in my locker is going to be quite a bit larger then the dimensions of the locker. Thanks.

A custom sac may be a consideration in the future, but not right now...so looking for other options.

your absoloutly right the bag will conform it self to the shape of your locker. I run a 750 in my vlx and i can only get around 550# of water in it but it fills the whole locker. make sure to look around your locker for sharp objects that might not agree with a sack. other than that look at the partition between the locker and the motor. i have herd of some people adding a stiffner of sorts. mine curves a little but nothing im worried about.

Thanks, yeah I am a little worried about a couple sharp corners but I figured I would 1) get a pro series sac that seem to be pretty bullet proof and 2) put something between the bag and the boat in those spots. Was also wondering how much pressure the bag would put on on the removable panels you mentioned that seperate the locker from the engine compartment but they do seem pretty solid. Anyway, thanks for confirming that. I've seen a couple good deals out there and figured I would try that out before getting a custom sac or going with the one closest in dimensions to my locker.

put an enzo style sack in your boat and you will have the second best surf wave on the lake. assuming some one has an actual enzo.. if not you will be the tops.
