Looking to put more weight in our mastercraft dd for wake surfing. we have enough weight as we just got another tube sac but the problem is the very little room. So is it safe to put one full sac on top of another? Will this like pop the one on the bottom?

I've done it but I'm not so sure its super safe. I use to do it when we surf'd, now everything is hidden. We'd do a 750 with a 400 on top of it. Fat Sac's are super tough but I could imagine it popping it.

Never had an issue with it. We stack em, walk on em and they are rock solid. Not really a safety issue, if the thing breaks just turn on the old bilge pump, your feet will be wet but it's the same amount of weight in the boat.

I wouldn't hesitate to stack the pro X type sacs but the old waterbed type may give you blowout problems. <BR> <BR>I have doubled the 400# and thrown a fat brick on top

Wow everyone jumped on this one <BR>Lol

I've stacked my V-drives a bunch. Even after the system was plumbed in, I would toss the extra 400 on a fill it.

Greg pro x type? Its just a fly high tube sac. Should that be allright? We've had people sit on them so I guess it wouldn't be much different <BR>,

Yep!

prob wont be a big deal as others have said just pump the water out <BR> <BR>had a locker sac explode full water went to bilge and pumped out

thanks for all the input guys. <BR> <BR>well apparently the sac is the waterbed type caps. the only problem is it didnt come with any caps or those rubber plugs. does anyone know where we could pick those up?? we tried local dealership, ebay, barefoot int. and local matress stores....
