Pictures of the leaks

Hey Mook I am a little confused: From One joint leak we now have pics of 17 leaks, some of which seem to be rivits, some worn areas and some joint leaks. Now you filled you boat with water, and that is how you marked your leaks, Correct?

Yet you were out on the lake for a few hours and got less than a cup of water in the boat, right?

I am posting these questions so all see them, so you can get the help you need. Isn't that back seat a little high for the profile of that boat?

yea i have the same concerns for the leaks and the seat.  I have been looking around for a 6'' swivel and haven't found one.  Muddy over these next few months I am going to remodel the whole boat.  I need to replace every peice of wood and mount the front motor on as well.  I am going to get 2 seats like yours and I am painting the trailer and boat. Most of the work I've done so far is on the trailer to make it legal.  It is my goal and a great project.

For the leaks I know it was leaking 4 times faster today then when we were out the other day.  Also some of the leaks in areas 3 and 2 are at or abover water line.  There is very little pressure there but I still would like to seal it once and for all.  The major problem is the bow and transom That I could tell.  Hey guys I hope the pics are good enough and we can get a solution.  Also if any one knows how to put more the one picture with a post I would love some instruction.  I am worried that my post will get deleted for posting too much.

Grouch- No need to cut/patch and weld,lol, however, my welder (Matt 50 on this board) will testify that although JB weld is great stuff, it makes welding tricky in that same spot. The same spots got welded because the JB is only permanent if you rarely use your bot or if you never flex it. The stuff is like steel, granted, problem is, steel doesn't flex like alum.

I had been using it to keep her afloat for the 1st yr, my original welder (Builds tuna towers for Nortons marina) refused to touch it because of all the "media". He said we would never get it clean enough. We did, but it took lots of heat,lol.

Either way, no need for the stuff anymore and the reason I use plumbers epoxy is because it is easier to remove than the JB when you are rerady to weld.

Granted, Sharkbites boat may be a perfect JB candidate, my point was, let's sand it down and see first.

Sharkbite- Sand with any sandpaper from 35 grit to 1200 grit. 150 would be ideal though. You can use a piece of paper by hand or an apparatus on a drill, doesn't matter, we just want to see the bare metal and the structural damage.

LOTS of pics please, different angles.

;)

LBH In the pics only the bow to the transom are sanded b/c I when I took the boat out on sunday there was no water coming in from the side joints.  Once I filled it up with water it started to leak.  I think this is due to the pressure and not any damage.  Also me and Muddy are wondering why does it leak more when filled with water but when it was on the lake after 6 hours I only had about a cup of water in the bottom.  The leaks were at the bow and transom only when the boat was on the lake.  While sanding there was no lose rivets or any holes it look more like old sealer or something like that.

Wow...that isnt just one small leak. The whole seam is coming apart. Do us a favor and take a picture of the inside of the boat looking at that same seam.

Yes please

Grouch- as I understand it, he filled the whole boat so that side seam really isn't a big deal, above the water line. (I think)

As for it leaking more from the inside out, the seam never saw pressure like that from that direction before, actually, it only knows that pressure going the other way, from out to in, which probably was helping to seal it a bit.

Let's see a pic of the inside but from the looks of the bow, you may need to just replace rivets.  Lots of them, but winter's coming,....you have time ;)  Also, speaking of winter, don't let any water freeze in the bottom of the boat in between days when you're working on it.

You might want to reconsider how you have your boat up on those sawhorses. It appears that the weight of the boat, and the water in it, are resting on the boat's axle.

I know that when you change a trailer tire you need to put the jack under the frame, not the axle, to avoid bending the axle.

Somebody please correct me if I'm wrong.

ok guys i will get more pics my next day off anf I did take the boat down from that position as well.  I can also work on my boat in the basement threw the winter. Isn't there a sealer I can use guys?  I have never used rivets beforeo I would need alot of help I think.  like I said the leaks aren't nearly as bad on the water.  So JB weld won't fix this?
