I have a 1995 Lowe Aluminum riveted boat that has a small leak below the transom where the back panel meets the bottom of the hull. I am curious if an aluminum welder might be able to place a bead along the seam to fix the leak and prevent any future leaks. Any help would be appreciated. Thanks!

A good welder can indeed fix it.

Yes that can be fixed. I had a crack on the front of mine
Cost me 75$ to get it welded
His welds are better than the factory welds
Good luck finding a good aluminum welder

Magill's in Lewisville can fix you up
