Anyone remove hard tanks & just go to big sacs?

Hey Guys,

Currently have hard tanks (250#) in lockers with 800# bags on top of them in a piggy back fashion.
The piggy backs Take forever to fill and I usually end up filling from the top while the hard tank fills from the bottom to speed up the process.

Has anyone removed their hard tanks and replaced with a much larger sac tied into the onboard pumps?
If so, did it help with fill times and did you need to build a sub floor where the tanks were or did you just put the sacs on the floor of the boat?

Thanks in advance.

Depending on the boat, cutting them out is the only option.

No clue what boat you have, but my 03 X30 had the hard tanks in the lockers. Pulled them out and put 1100 in each locker. They take a while to fill, but I can live with it. I'm still running the stock 3 pumps off the manifold, but at some point I'll give each pump it's own thru-hull to pull from. That should speed things up a bit.

If you do take out your hard tanks and they have sending units, I would like to get them off you. I want to experiment on the sending units to see if there is any way to make them more reliable. What year is your boat?

Thanks for the feedback guys.
My boat is a 2010 x45.

GWeaver - when you removed the hard tanks, did you have to build a carpet lined subfloor, or was it smooth enough (no rough edges) to place the bags directly on the floor?

You can fit 1100s in there with the hard tanks

My lockers have a floor and are carpet lined from the factory- the hard tanks were little 300 lb units mounted against the hull sides.
Not my boat, but I have something like this:

Thanks GWeav.......yours is nice and clean. My tanks are beneath the carpet.
So after removing, i believe i would be left with the raw inside of the hull & misc hardware exposed unless i built something to protect the bag.

Aric - yeah i know you can get 1100's in there, problem is that you cant fill em all the way.
800 is the largest bag I've been able to fill to the max.
Was hoping with removal of hard tanks id be able to get 1100 bags to fill and for it to be more efficient.
Just not sure its worth the hassle at this point.

Thanks guys.

If you pull the hard tanks, it shouldn't be too hard to glue some carpet down on the bottom. That should take care of your concerns about hard edges. Having not seen the space you're dealing with, I'd think that building a subfloor might be overkill- plus if you just carpet the floor and lay the sacks down on that, they'll sit a little lower and you'll have a little more room for storage, even when they're filled.

My hard tanks were cracked in my 2006 X30. I pulled them and the starboard with the carpet on top of them and put in 1,100's. I did not put carpet down and I'm good with it.. The hull isn't raw fiberglass and looks like black gel. I can fill the 1,100's all the way and still have room at the top of the locker to throw in a couple wet life vests. Not sure it did anything to change the fill times. I too am considering the dedicated 1" thru hulls to speed things up.

The two things I didn't care for was the engine divider panels used the carpeted flooring from coming into the storage compartment. It's been on my todo list but thus far hasn't actually been a problem. Of course I usually have ballast going so that keeps the divider in place. The second thing is the compartments are crazy deep. You almost have to crawl into it to get anything out if the ballast is empty. Used to it know but when I first did it that was a shock.
