View Full Version : Cracked Ballast Tank - Help
08-07-2012, 03:30 PM
I just recently found a small crack on the top seam of my port ballast tank. 06, X-Star. I always drain them over the winter, I just believe the pressure from them filling into the secondary tanks may have caused the crack. Has anyone ever had to patch the plastic tanks? And if so, how have you done it?

I have the same issue with my center tank on an X15, tried JB weld, it held for a little while but then blew off. Trying to figure what is my next plan of attack.

Plastic weld would probably be the best solution. It would ensure no leaks and is fairly strong when done correctly.

Probably need to use a plastic welder. You can buy a gun and welding rods at harbor freight cheap but you may want to consider having a body shop weld it as it is somewhat tricky.

We've been cleaning and scuffing the area up and then coating with 3m 5200. So far its worked just fine.

I purchased the a Urethane Supply model 5600HT from Amazon for $150 and have found it to be a great tool for these kind of fixes. I haven't done a ballast tank yet, but I've fixed a radiator overflow tank, a fairing on a moped, and an inner fender liner on my car. I've found a lot of uses for it and it has already paid for itself.

This might be a good reason/chance for you to really improve your wake and bypass those rear tanks. I did this years ago, now I have (2) 720 lb. FlyHi X-star sacs plumbed in place of the rear tanks. They fill/empty automatically just like the hard tanks did and you will have over 1400 lbs. where it's needed most.....at the rear corners of the boat. Fill the KGB and add a 750 sac to the walkway and your wake will be awesome! (You can always just fill the rear sacs 1/2 way or less if desired)
The 720 in the port locker helps a lot with surfing too.
Regarding fixing yours, plastic weld should work the best. MAC TOOL and SNAP-ON both sell plastic welders if you want to try that.
