options options… I would go JB and give it a try crack does not look terrible. I know it is gas but JB is very strong and bounded well on my broken skeg been good for years buy the JB for your metal type, patch and sand smooth … you can always go solder if it does not hold.

If you use JB Weld you should use their gas tank sealer. This tank sprung a leak this summer. Being away, I used it so I could still run the motor. I made the patch large enough to give it the best chance to work. I ran the motor on and off for about 6 weeks. It held up fine. If the tank is too thin to be welded I’ll be looking for a replacement. Just putting a thin line on your crack isn’t likely to be sufficient. If you don’t mind having a lump of it on the tank, it would be the easiest and least expensive option. A gas tank sealer wouldn’t be visible. PRO sells an 8 oz can that isn’t too expensive.The best repair would be soldering IMO.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

so when you fix it, what will you (or your welder) use to remove the tank sealer material?

Well I hadn’t given that much thought. Your comment got me to thinking. Several things occurred to me. I decided I’d try the chisel first. While that’s working it’s not just popping off. Took 3 try’s for the first piece to come off. I chipped off a couple more. I’ll get the rest when I get to it. I’ve never used this stuff before. It’s really stuck on there. No sigh that the gas had loosened it around the hole. The tank had a patch in it. I wouldn’t put much gas in it to barrel test the motor. First time I filled the tank was when I put it on the boat. An internet search came up with this stuff and it was easy to get. I cleaned the tank there really well and scratched it up with some sandpaper. It worked great for what I was using it for.
