Jon Boat Transom Fix: 3M Marine 4200 Quick Cure 3of3
HTML-код
- Опубликовано: 22 июн 2018
- The T6 Aluminum plate is powder coated and mounted to the jon boat transom. The plate is bolted through the transom and sealed with 3M M5200. We now sealed all the bolts that go through the transom with 4200. Some of these bolts are below the water line, but most of them are above the water line. I used 3M 4200 just in case I needed to remove the bolts again. If I used the 3M 5200 on the bolts, people said I would bend or tear the aluminum before I would be able to get the bolt out. So 5200 is permanent, and 4200 is strong, but not as permanent = semi removable.
Bolts used - Stainless, 3/8", 2.5" long
Washers - Flat Stainless 3/8" Fender Washer
Lock Nut - Stainless 3/8"
3M Marine 4200 - I treat it like 5200 but use it for applications where I may need to remove that item. 4200 is still very strong and seals great, but its removable.

Anybody else hear the elk at 0:18 seconds? Got me excited! But on a serious note thanks for the videos on this they’ve been very helpful!
Hahaha I wish. Those mocking birds can really mock anything they want too haha thank you for the support, I'm glad you found it helpful!
Nicely done :-)
Glad your posting these videos in case I have a issue with mine in the future.
Thank sir! I hope you never have too 😂 this has been one long project and too much time off the water!
Thank you.
Bolts in wrong way
I did the exact job your doing bolts though the transome except I was bolting on a engine pod to mount a out board. the bottom bolts sweep water not good. seamed like I was constantly pushing the glue out the hole, I'd cover the intire bolt generously and push in then pull back trying to surond hole w/ glue then add generously under both washers, I need to stop this water intrusion.I used 5200 and waited 2 weeks before mounting engine. thanks for any tips.
There are a couple of things I've noticed since I've done it a couple of times. The first thing is to get the proper size bolt for the hole as in, make sure the bolt is a tight fit. Then I push the bolt through halfway and then start adding the 5200 to the bolt/hole and spin it to get as much as I can in there. Then make sure your surface is flat and even so that the washer sits flush with that surface, and make sure to use a bigger washer like a fender washer, put a good amount of 5200 on the back side, and don't over-tighten it where the washer starts to flare. Best of luck!
I would have installed the bolts going the other direction. Would have made for a cleaner looking installation. Just saying.
The reason I installed the bolts this way was so that my leg, rope, or anything that was inside the boat would not get caught on the end of the bolts.
Looking good. One step closer to the finish line. Hope all is well with you. Keep up the great work. Just one ? What is the cure time on the 3m 5200 and 4200. I wanna buy some to seal up some stuff on a livewell im working on.
Thank you!! Getting close to getting it on the water! So there is, 5200 regular, 5200 fast cure, and 4200 fast cure. 5200 is for a permanent seal. Something that you never plan to touch again. 4200 is for things you may want to remove later on. Both 5200 and 4200 are good for below the waterline use. The 5200 regular cure takes 7 days to cure. the 5200 & 4200 fast cure will cure in a day or two and it keeps about the same strength, just a little weaker but not by much. So for your use, if its a part or fitting that will need replacing or moving down the road, use the 4200 - amzn.to/2KbajND. If its the container, or something you never plan to touch again, the 5200 fast - amzn.to/2KbRLwQ
Do you need aluminum bolts for the transom? Or can I use stainless steel?
All the bolts I used are stainless steel and I have not issues to speak of
I just picked up a Lowe 1436 and it has nothing on the transom. No wood or anything. Is it ok to run this way or should I do something like this with it?
I would have to see it to give you my input. You can send me some pictures on facebook if you'd like?
I don’t have it anymore or I would lol.
if you had to redo it, are you sure its the right stuff to use? ive heard to use this stuff and ive heard the only way to go is epoxy.
If I were to redo the transom, the would use the same stuff I used. I did my research, ask around to a few friends in the boat building community, and feel confident in what I did. It has held up so far without any signs of issues.
@@JTgatoring ok just wondering cause im redoing my whole transom on a boat i just bought
@@wholeass83 Yeah, if its a jon boat like this, I would use 5200, but if you're doing a fiberglass boat then I would do epoxy
I'm looking at the bolts on your list and you say 3/8" by 2 and 1/2" the bolt in your hand looks to have a thread length longer than 1"and the longest thread length I can find online with a shank length of 2 and 1/2" is 1" thread length for fine and course thread Hex Bolt. So the only thing I can think is maybe that isn't a Hex. What bolt style are using?
I don't know what thread length it was. I just know the hole I drilled was 3/8" so that was the diameter of the bolt I needed, and the length of the bolt from the bottom of the hex head to the and of the bolt was 2.5" long. Being in the water environment, I went with stainless steel and I do not know the grade of it. www.boltdepot.com/Hex_bolts_Stainless_steel_18-8_3_8-16.aspx has them. I just got mine at my local hardware store.
@@JTgatoring Well I ended up at my local Lowes and they had a limited amount of stainless that size but I did by chance find a stainless hex head bolt that is 3/8 wide 2 - 1/2 long with a thread length that looks a lot like yours. Internet is great sometimes for ordering stuff just couldn't do it with the bolt but had to be something you could touch before you felt right about buying it. Got everything I need now when I'm done I'll send you a pic. with the transom mod and engine mounted. Went with the shaft you recommended for the long tail.
@@evanbell3238 I'm glad to hear you found the bolts. I got mine at Lowes too. I would want to buy the bolts in person anyways, and not from online. As long as they will fit the thickness of your transom and your support plate you should be good. I look forward to the pictures of the finished project, and even some while you're doing the project. Facebook or email would be best to do that 👍 best of luck!
How has that held up ?
Great. Still going without any issues. Its water tight and the transom is straight
How hard would it be to break those bolt free if needed?
I should be able to loosen the nut and then spin the bolt free with a rachet. If I can't pull the bolts out by hand, I would just back the nut up to the end of the threads, use a hammer, and tap the bolts out. That's why I used 4200(non-permanent) on the bolts instead of the 5200(permanent) which I used on the plate-to-boat surface.
If I was a betting man. I'd bet everything else would leak but that. Lol
🤣 now that you say that, I would have to agree hahaha hopefully the Wetlander keeps the bottom sealed, and we all know this transom shouldn't leak. It will be an interesting first day out on the water!
JTgatoring like always bro. Good video
5200 or bust
But seriously tho im using 5200 to do this ,, is that alright ??
haha yeah! It works for that! I just did 4200 so it would be easier to remove the bolts if I needed too. If you don't plan to remove them then 5200 all day long boi
@@JTgatoring thanks bro., i have an important question !!! I have jb weld marine , i was going to.use it for 2 or 3 leaky rivets , should i just use the 5200 instead???? I might go do it here now thanks !!!!
@@ticesine6589 I haven't that good of luck with jb weld... I've had it fail a few times on projects. 5200 I have never heard of failing. I would do 5200 100%
@@JTgatoring yaa huh ? Ive heard some good things about the jb , i wasnt really familiar with 5200 until i watched your vid. Your boat is nice man , i just have a 12 foot crappy v hull , i am glad i messaged , i figured the 5200 would be good on the bottom seams and rivets. I guess ill need another tube . i checked the bottom of boat yesterday and right at the back bottom where the spines start , there is three perfect holes at the start of all 3 spines. It looks like maybe there were rivets there ? There small but it looks like water would fill all the spines ?? Should i fill those ? Im thinking yes , im just getting going as im in canada , the snow is finally gone . thanks again
How thick is that T6 plate?
Quarter inch thick
Where did you get that plate at ???
