Second question, I have a small pin hole in my left Toon, realized there was an issue when it started leaning in the water. I pulled it out and it is located at the bottom rear of the Toon. If water had not been coming out of it would have been almost impossible to find. Now my question is some people have told me to take it too a Marina and get the hole welded. Others have shared to just put Marine Epoxy over the hole and it will be fine. Any suggestions or thoughts on this idea?

         Any time you weld below the water line it is a good idea to pressue check. When the transom in my rebuild was cut in beleive it or not there was not a single leak. Now as for the strakes I can't say the same. My buddy that welds had to use a rod he didn't want to, his supplier was out of the welding rod he wanted. What happended was on several of the welds was after running a bead at the point where the rod was pulled it left a tiny pin hole. They were so small that it did't hardly leak down on the guage during the test. We hit the water and what do you know we had water in the logs after a few hours. It took the soap water trick to locate them. You could spray the spots and it would take several minutes but a big bubble would appear. It was an easy fix for him but also a good exaple of why you need to test after you mess with anything below the water .
 
As far as repairing any holes with gule ,epoxy, or what ever I would be very hesitant. A good welder could fix those spots. I don't have an answer as to how to find a good one but you need one that can work on old aluminum. Alot of guys are great with new clean metal but the old stuff requires extra prep. Applying glue will just make it harder for a welder to fix it when it starts leaking again.

I had a small pin hole leak in one of my toons. I used JB Weld Marine Epoxy to fill the hole, however I now believe that I may have more than 1 hole in that toon. I have searched all over the Internet for hours and hours and can not find anyone who has done their own repairs by applying air pressure to find more leaks in the toon. I have found plenty of precautions and I understand not putting more than 3 to 5 psi etc, but find hard to believe that no one has step by step procedures with material breakdown to make a pressure tester for toon?? Has anyone on this forum done such work befor or know someone who has?..

     After all of the welding was done on my logs ( added strakes, transom,drain plugs) we pressure tested. We never even had to get more than 1 psi in to find the issues. It takes along time to get any real pressure in even with a big compressor. To help find real small leaks spray the logs with a soapy water solution. The big leaks are easy to find it's the little ones than are a pain. If you know what size plug you have it would be easy to go to the plumbing setion at a big box store and assemble what you need. Tell them you need to pressure test at low psi and they could help you out. Also remember that most logs vent on the top so you'll need to plug those before you try and test.

That's some good info Shaun, I have a decent sized crack in one of my tubes where the riser is welded to the tube. Mine is on the nose cone, I'm almost positive that on my tubes the nose cones are sealed because I can tilt my trailer all the way up and even after about a week of sitting like that the water still hasn't drained to the back....Since I plan on getting a donor boat when I do the 3rd toon I'll replace that tube altogether since it has a big dent in it that looks bad. I need to in the mean time drill a hole in the top of that nose cone and try and siphon the water out and plug the hole with a screw and silicone and patch the crack with jb weld or something!

Thanks for the information guys, VaGent has offered to help me with a gauge that he made to pressure check the toons, I will give him a call tomorrow. I have to admit for as many companies that are out there who make pontoons I am surprised at the lack of information that there is about how to check for leaks or repair them. Seems to be plenty of their ads for new boats but very little on repair or maintenance. Very sad.

I have never known of a boat manufacturing company of any kind that will tell you how to do repairs in writing. After all, its what they have repair shops for. On the other hand I do know of boat manufacturing companies who will give you leads or other good info IF you get the right person (better in person if possible) on the phone from one of their dealerships.

I understand what you are saying just my own frustration and venting. Just saying I wish there were more solid information, I called 2 different dealers and neither one would work on finding or repairing a leak. I called 4 marinas and got 4 completely different answers ranging from use epoxy, weld, use truck liner paint? Etc..... doesn't make you feel too confident when there are so many answers and opinions but hey as I learned in the Navy everyone has an opinion just like an as..... I do appreciate though all the help that fellow Pontooner VaGent has offered to me he has been awesome with his advise.

I've never had a dealer do any welding on my toons. I always just took it to a welder. Alot of dealers farm out the welding work anyway.

Excellent Shaun, I know myself, I'd want to see the previous work of a welder and as Les can attest to, (and cuzzx) there are good ones, so so ones and EXCELLENT ones, so it pays to see the work. You'll know instantly if he's an excellent welder.

there are several types of rhino line, speed liner and so on.  They advertise for boats. The product can be as thick as 1/2 inch.  Has anyone heard of repairing leaky toons with this stuff?Wink

Yes one of the welders I talked with stated that he and others had been using the bed liner paint for toons for a few years now and have had great results with the product. he said apply several thick coats and let set for a few days. He said on a badly corroded toon it's about the only way to seal up all the tiny pin hold leaks that can develop.

Wonder what the prep is like and how much weight it adds to the tubes??  Smile

If you can find an inspection plug on the top of the toon, then let it sit open overnight, then close it first thing in the morning, and allow the sun to shine on it.  The toon will become pressurized enuff for you to go over it with a spray bottle of soapy water.  You can verify this by opening that plug again in the heat of the day and hearing the warmed up air gush out.

This might be true in a case where some one is trying to save an improperly maintained tube used in salt water.  How ever, there is really only one RIGHT way to fix a leak, and that's to weld it.  The "hot day sunshine" trick works, I've used it before.  For multiple leaks or hard to find leaks, you will need to put pressure to the tube to find every thing.  The reason there is no "manual" for testing is simple... A) Most toons are different.  Some have separate chambers, some are vented on top, some have different sized fittings, etc etc etc.  B) No manufacture or dealer wants take the liability for the D-I-Y guy.  If he tells you "do this" and you sink your toon he doesn't want you coming back with a law suite.  Unfortunately it happens too often these days.
Feel free to contact me for help on your project!
