FINALLY! Thank you for speaking up and showing others how to PROPERLY perform this repair. Great job! I posted a very similar video years ago and was attacked for such a "flimsy" repair...this is THE BEST WAY to repair a small aluminum boat leak if caused by fatigue cracks, splits or minor-moderate hull breaches.

Thank you for the comment!

Great job on this repair. Drilling the end of of the cracks creat relief holes. Not sure if you knew this but, round patches are a great patch because corners create stress points. When creating patches in aircraft structure, square patches have a radius or rounded corners. I would recommend installing a few rivets on the inside perimeter to better secure the patch an feom the outside to increase the life. An added piece of aluminum on the outside, known as a doubler would be even stronger. Overall, great job.

I hope to never have to use this but super informational! Great video, Matt.

I'm glad it helped you! And yeah I feel that. The first time I repaired a leak I brazed too.

Great Video!! A simple drilled hole CAN be brazed. A spider crack like what he is dealing with is cracked because it is under stress and takes a fix like this. What he is doing will definitely work and then some!!

Nice Job Young Man.

Ok. If you are going to say use 5200 (a 3M product) don't show a Loctite product. Also, 3M 5200 is not very flexible once fully cured. I would also recommend checking out another very popular channel where he puts the most common brazing rods to the test. There are 3 brands I would use for this repair over an adhesive patch and one of them can be found a harbor freight.

@EngineeringHooksets

Жыл бұрын

Yeah Ive used 5200 in the past and I misspoke about this, my bad. I disagree, doesn't matter the brand, if the aluminum hull isn't melting with the braze rod the bond will never be great on a flat surface. I learned that twice the "hard" way.

Looks like a nice patch. Should be good to go! Team Brazing Rods be gettin clowned up in here.

Yes, but legit aluminum welding on a 1/16" boat hull is incredibly difficult, and 99.9% of people are unable to do that. This video is for the rest of us.

Would it be worth using an etching primer?

Great video! For what it's worth, the Loctite PL Marine that you used is more like 3M 4200 than 3M 5200. Loctite PL has same hardness rating as 4200, and 5200 has a higher hardness rating (less flexible, but a stronger bond). Have you used both 5200 and Loctite PL to do this and had equal success? I've got a leak that is under the end of a rib on my boat. I really like the technique you are showing, but will have to remove the rib to do it. A little worried about doing that.

Just tried braising with alumiweld sticks and i cant get the metal hot enough. The boat is just a giant heat sync depiste using two torches together. It looked like the braize took but i filled the boat with water and it still leaks like a seive. I tried to pull the old solder out to try it again but i ended up just ripping a larger hole in the boat. Id try a poropane oxygen torch but that much heat may just blow a biggger hole through it. Ill try this next. Trouble is its on one of the ridges that run the length so itll be hard to get flat.

Who are you to claim that brazed repairs aren’t going to work? I bought a bought years ago that had circular saw cuts in it because the previous owner thought it made a good plywood cutting platform. I brazed those gouges and holes closed with patches and aluminum brazing rods. I turned it into a jetjon and it rips through chop and waves all the time. Those repairs are still holding. No water gets into the boat from the bottom.

@EngineeringHooksets

3 ай бұрын

Who am I? Oh, just a guy that brazed 3 holes on my boat, and they all started leaked at some point. And no, I don't think I did a particularly bad job or anything. If brazed patches are working for you, you're probably not bumping your boat into any rocks or stumps. Brazed patches fail when the hull flexes

Why didn't you weld first

Yeah I would never put a bandaid on my boat if it's aluminum weld the aluminum and if you know how to use brazing rods you have the boat heated to the right temperature will suck the brazing rod down into the crack of the boat able actually Bond to the aluminum what you did is the same thing the previous owner did with the JB weld it'll work for a while but for someone like me who is putting a Bass boat floor and subfloor and my metal boat and I don't want to have to tear it apart to re-fix a leak when my silicone starts falling apart I will just weld aluminum

@christhomas1465

Think it depends on the boat. I agree weld is superior, but if the boat is full riveted, you run the risk of blowing out a seam seal by overheating it while welding. Heat sinks while welding help, but ya better know what you're doing.
