| Aluminum Boat Repair........... (Posted on 12/3/12 at 3:08 pm)
I have a small hole in the back of my aluminum flat (probably about the size of a small twig). Anyone know any welding shops in the Metairie area that can fix this? Can I have someone come to where the boat is being stored so I don't have to haul the boat out?
Any idea on what this will cost?

They make this aluminum putty stuff that is sold at West Marine. I used it on a bunch of spots on my flat boat and it hasn't sunk yet. It is a stick with a 2-part catalyst. Break up the stick, mix it together, and wait an hour or so and you have a patched aluminum boat. You can also grind on it to make it smooth after it dries
FWIW, I scuffed up the repair spots with a rough flap disc so it would bond better.

How big were the holes? Were any on the bottom floor that would be in contact with the pressure from the water?

This, but first you have to remove all dirt,oil,ect with a brass brush for it to stick real good. You will never have to repair it again in that spot.
Oh, do it from the inside if you can.

Some were the size of a quarter with half of a dime attached. Some on the transom below the water line. None in the floor though.
Bigger ones definitely take more work, and are harder, but it can be done.
Post a picture of the hole

Boat isn't at my house(will try to get a pic), but a good point of reference may be the hole may be slightly larger than the diameter of a roofing nail.
So with that being said, is this stuff ok to use on the floor of the boat? The hole is located in the very back where I keep the gas cans going to the motor.

I would do it, but that isn't saying much. It could work 99/100 times, but you could get a bad batch or not prep correctly. That is a small hole and I would go for it. Bring a pump just in case.
Disclaimer:
As a temporary fix, it should work fine. Your boat could sink though. It should be welded for a permanent fix. Do the prep yourself and have a mobile welder spend 3 minutes on it

All over the place. They use engine-driven machines. I have had a few of them drive up and ask me if I needed anything done before. They either bring the stuff with them in their truck, or on a trailer. All they would need for that would be a simple spool gun and some wire
Look up Mobile Welders Metairie, LA

I actually just went through this last weekend. I had a 1436 i bought that had 12 leaking rivets and 3 other leaks about the size you are describing.
I repaired the leaks by drilling a 1/4" hole through the leak, and putting a round head bolt through it. Did the same thing to replace the rivets. You can do this for very cheap, and it is a more permanent repair than JB weld or any other sealant.
Use stainless round head bolts, washers, and nuts, and place a nylon washer between the aluminum and the stainless to prevent corrosion.

You would crazy to pay a welder a dime to repair this pin hole. JB Weld is all you need. I've repaired many holes up to dime size gashes with this stuff. Works 100% of the time. As said just clean and rough up the area.

You can probably bring it to any welding shop nearby and they'll do it. A dude in town welded a crack in ours, and made a trolling motor mount and a couple other things

If you do end up using a bolt, I strongly recommend getting some plumber's goop and putting it all over the threads and head of the boat
