Thread: Transom Crack

FYI, your transducer and all silicone around it will have to be removed and all moisture will have to be out of the boat/crack for that to be welded.

Got it!

That weld looked like it had been ground down thin. Didn't look like they had veed it any either

Furflyin, I use to weld alot yrs. ago. Would you heat first and find the ends of crack , then drill a hole at each end of crack ? Would you weld with 4043 in spool gun or tigweld with 6063 and straight argon? If my memory is rite don't some use helium for a hard weld ? I've got a 3035 spoolmate and just burn 4043 with str. argon

Yep, bunks should always go past the transom on an aluminum boat.

If the boat was sold that way new, then they put the wrong trailer under it.

We don't have any spoolguns but yes, I'd use 4043 alloy wire in our low frequency pulse MIG welders. We use a push/pull wire feeding set up with Alumni-Pro guns. The Miller 350P welders are new technology for us. We upgraded last year from Deltaweld's with XR boxes. The pulse welders produce TIG like welds with MIG speed. Great penetration, no spatter and fast. Yes, you always have to find the ends on cracks and drill them out, or at least I require that here. Not sure on the Helium, never tried it.

I suggested to rcliffingham in an attempt to keep him from having to drive over here to try and find a local place that welds up cracked aluminum rims for automobiles. That's going to be done with a TIG welder most times and if someone can TIG aluminum rims, they can handle a boat repair. If he can't find someone I think he's gonna pull it over here. That suggestion goes out to everyone. Find that guy in your town that repairs aluminum rims and let him weld up your boat.

Thomas Welding in Elkmont Al can fix it. Fixed mine. High frequency TIG.

Hey I went back and re-read everything. Guess how I know Eddie Thomas at Thomas Welding can fix it. Cause I got the same spots on a 2008 VT Triton. I bet if you look on top of the transom....at the motor well you'll find cracks there as well.
