Hey this is Donnie Smith and we've been working on this boat and we discovered that our block has a crack in it. So, we've done a little research and I heard that JB Weld might can fix that so we're going to put it to the test and see. We'll see if that works or not. From what I found on research they've tried it and never really heard of it work so we're going to give it a test, we'll take it to the lake and see and I hope that this works. So anyway what you're going to need, this is regular JB Weld. I went to the website just to see if it might work for this it says it can work on cast iron still and you want to get just the original JB Weld because it holds better heat resistant. I think up to 600 degrees and takes a little longer to drive but that's all right. We'll let it drive since here 15 to 24 hours. That's generally with any adhesive the slower it dries the stronger it's going to be. It's real fast dry and all that's beneficial sometimes but it's not going to be just quite durable, quite as strong. So also to do this we went and got us a little dremel tool so that we can clean that off so we're going to need that. We're going to need the JB Weld and also on their website on JB Weld's website basically gave two options they gave acetone or lacquer thinner. That's the only two options they gave for cleaning. Acetone was a little bit cheaper just a few cents so you want to be fine but we went ahead and went with the acetone. You'll need some rags to clean it with. We got a few additional dremel bits. We'll kind of experiment with that. So and got some lighting because there's another one in there because I think it's really important to be able to see real good you know make sure that you do have both ends of the crack you know you've got them located. First thing unfortunately it's inside of this and that's why we got the dremel tool so maybe we can get it in there a little easier. It's going to be a tight fit not a bottom room to work so what we're going to do first is we're going to take this alternator off. Alternator off just to get it out of the way. And first before we do that we're going to disconnect the battery so we're not short of anything. So we'll get the battery disconnected, get the alternator taken off and then we'll do back. Okay here I'm using the acetone I'm wiping it down just to get all the oils and grease off so that it's clean when I start working on it and I got this dremel tool and now I am starting to grind on it. Now basically just located both ends of the crack and trying to grind a groove in there so that this adhesive has something to hold to. Tight fit and also you know can get the camera in there they're real good. It's kind of hard to tell what's going on but I basically got some different dremel bit tools to try to clean this up and beat it out. Okay first I use a little wire brush that comes with it and that's to just cleaned up real good. Not to locate it, cating each end of the crack. I'm just partially drilling in there to help prevent it from cracking any further. Now I've actually got a little grind in the wheel that comes with the dremel and I'm starting to use that to actually grind into the metal. Like I was talking about some kind of cut that out and beat that area out so that gives an ease of something to hold to. Now I've got more of a die grinder bit that comes to a point and what I'm doing this is just going right where the crack is to help give that a little more depth where that is. Now I've put another end attached to it on it's a little round sander and I'm using it just to go extend past the repair area so the JB weld will go past that and also adhere well to the surrounding areas. Okay I've got this JB glue here, JB weld and it says to mix equal parts so I'm just going to get it mixed together really good. Okay I've got it mixed up and I'm just going to fly it to that entire area. I'm going to use it like body floor we pushed down pretty tight, hoping that it's going to push down in that crack and encrypses that maybe the groove that I ground out, what I'm going to do is I'm going to do a little bit more and put on another coat. Okay we had problems getting it started so we charged the battery up and we wouldn't get some of these muffs. I'm trying to get it started so we don't have to run back to the lake see if it works or not so. Okay follow me and let's see what happens. Okay we've got the water turned on and let's see what happens. Okay so the good news is where I repaired the crack at it's not leaking and we've been out with the lake three or four times and that repair has not leaked. The bad news is we found you know it must be another crack somewhere else but we decided just to go ahead and take a boat out and we've been out several times and repair hasn't leaked. Wherever else it's leaking from it's still leaking that we've been out the lake having a good time. You can even see my dogs out there having a good time too but I would say this works. Now if it works for the summer or you know it's going to work for a couple years I have no idea but it's worked three or four times you know going out for like three or four times so. I would say this works for temporary anyway. Now this test was a little different because I did it for myself I was needing to see if this worked or not. If you need something test let me know.
