Grumman 1437 . Looking for some tips

[Shallowman]

Hello , I recently picked up a Grumman 1437 Jon Boat. Overall its in good condition. After searching posts i found answers to a lot of questions i had , But still have a few more.
I water tested the boat both in water and filled the boat with with water at the house . Overall i noticed 3 leaky rivets , 2 of them i was able to fix easy . I want to put Gluvit on some other spots inside to be safe . I may decided to do the whole inside floor rather then spots, if i do that what is the best to use to get it prepped properly ?
The bottom of the boat one spot looks rough ( see pic ) but oddly the rest looks good ( see pic ) I can see where someone used jb weld in a couple spots, should i remove that and refix them also ?
Last one is a different owner added alum. on both transom sides for extra motor support . This appeared to be just caulked and needs fixed . The gap is visible and iam worried about that (see pic ) I noticed it leaked when i water tested inside the boat and tilted the water so it was high in the back.
After i get these fixed i will start i minor conversion . From what i can read on the boat sticker the boats holds only 335lbs. So iam not real sure on where to place batteries and livewell ect.

If the inside is NOT painted, then wash it and scrub it with a stiff bristled brush with a 50/50 mix of water and white vinegar. This acidic mixture will insure that the Gluvit adheres to the aluminum. If it is painted, you should use a wire brush on a drill to remove the paint.

I'm just sayin...

Thank you , i started earlier with a wire wheel around the leaky rivets and a couple that looked rougher then others .

Any ideas around piece mounted to the transom ?

Thanks for the tips , upon further inspection ---- i feel iam getting way to deep for me ..... The transom needs replaced and the Alum part is really bad looking. Someone had put a sheet of Stainless over it for added motor support it was leaking .When i removed that to reseal , it was all down hill from there . Guess i'll see what scrap Alum is going for now .
