My 130 gallon is leaking and I was wondering if there was a way to find out from where to have it fixed. Or is it worth it to have it fixed ?

You can coat (paint) the interior or have a bladder made for it. You would have to remove it to weld and it may be corroded to badly for that.
If you remove it it may be cost effective to replace it with a poly tank.

When that happened to our 45 upper tank we cut the bed frame above so we could take it out and rotate it to inspect all sides. We were able to get a welder inside the boat to make the 2-3 repairs necessary to get it back into shape.
In our case there were a couple or more spots where a metallic object was between the aluminum outer tank and the fiberglass hull which caused both corrosion as well as abrasion over the years generating small spot failures which were impossible to see unless/until you could inspect the lower sides.
Hope this helps and good luck

Mine would leak only when full and underway, if the tank wasn't full it didn't leak. If it was full and not moving it didn't leak. Turns out the pressure added to the movement opened a couple of hairline seam leaks only under those circumstances. Finally opened the bedframe and had a welder (with protective coverings for things) spot weld it in place. Solved the problem for going on 2 years....hope it helps

Hmm that's interesting having just spend a LOT of time researching and resolving this problem myself.

Do you have any links to safe tank coatings used to repair aluminum or examples of bladders that will work with a baffled tank??
