Mastercraft X46 rear ballast crack

Hello

my starboard rear ballast developed a leak
the leak is coming from the original welding at the top rear side of the hard tank.
It is frustrating because you can see it but still very difficult to access for welding. I manage to do a first repair but unfortunately, it still leaks (I used a dremel small gas torch with a modified tip and after checking the temperature was about right or about 300 deg Celsuis)

since then I ordered an electric welding iron made for plastic welding, so i will try again to weld

1/did anyone experience the same issue? how was it sorted?

2/can I remove the hard ballast tank from a X46 without separating the hull

3/what about cutting the tank to pieces and replacing it with a soft bag?

thank you for your help

Fred

Buddy with '14 X46 had his replaced under warranty, had to split hull like Blakey above. Norcal MC did his, but others may be sent to MC HQ if stateside. Not sure of your options in Europe?

You can try to plastic weld it, however this is really hard with the tank in the boat. The tank is HDPE, so make sure you get the correct welding rods. I purchased a welder from harbor freight & the HDPE rods from Grainger.

I was not 100% successful with the weld as I still had pin whole leaks. Also, I never found anything to really bond well to HDPE, 3M 5200, Flex Seal, etc, it all sticks initially, covered the pin holes, but just peals right off if you rub it. I was not happy with the fix for the long run & was able to get the starboard side tank out via the coffin & replaced it.
