Punched a hole in gas tank
Sea craft my dream boat, I watch the site often love to see a classic returned to better than new. I am coming to you guys because your the best.
I have a 2005 North Coast CC . had a guy ad speakers & amp over the winter. He punched a hole in my gas tank, He either didn't know or didn't tell me. I filled up the tank before launch and discovered gas in the bilge. The tank is cross link polyethylene I am told this cant be patched, if it can't I was thinking about a "mechanical plug" Any suggestions or recommendations. I will open the deck Monday to see what we are looking at, but I am pretty sure he put the drill through the top! Any help would be much appreciated. Thanks in advance, Dick O'Donovan

Re: Punched a hole in gas tank
That sucks! I think if it were me I'd force an over sized aluminum screw in it, then cover it in a strong hard epoxy like Super 7 or something. Make sure you clean and sand the tank surface first so the epoxy bonds well.
That should work fine. Just keep an eye on it. Good luck.

Re: Punched a hole in gas tank
Epoxy might not stick to the plastic tank, but there is some stuff called Seal All (Any ACE hardware store should have it) that is amazing. It will cure in liquid gasoline!
 I have temporarily sealed leaks in the BOTTOM of leaking auto gas tanks with it! Just put some of it on the threads of the screw you put into the hole. Tap the hole and use a fine thread SS machine screw with a fender washer on it to provide lots of bonding surface. I'm sure this isn't a USCG approved fix but might make a good temporary repair, and probably isn't much different than the way they mount sending units in top of these plastic tanks. Good luck!

Re: Punched a hole in gas tank
polyethylene is code for nothing will stick to me. the only thing that can be done is plastic welding. which means the tank has to be emptied and clean and filled with I believe Argon. To keep it from igniting. Who installed the stereo? If he is a proffessional its time for an insurance claim. you have to remember this is why there is such thing as insurance. This is a very serious situation.
I would not try to "rig something" to fix the tank you are only asking for very serious problems like blowing up when the bilge pump kicks on.
