two hammers hold one on rivet tapping the rivet with the other

If peening them tight as fence man suggested doesn't work, drill them out and replace them with pop rivets treated with a little RTV silicone, worked for me. Good Luck!

I've tightened them pretty much as fence_man described except that I used a special anvil-like tool designed for the purpose. 2 hammers or a hammer and metal block will work fine. Drilling and replacing a few rivets is not to hard. Replacing all of them would be ridiculous.

Oxbox, do pop rivets really hold up? They are much softer than the original rivets.

good thoughts on the hammering but i can not get to the top of the rivet i have a sub flooring...i should have mectioned that...i tried J B weld but it knocked off in the water while running ...i thought of the pop rivets but they are a little light for the application....

This topic gets brought up some what regularly. Other suggestions would be to pull floor boards and coat bottom with alum. roof coating or truck bed liner.

I have a similar problem with a rivet I can not get to the back side of. There is structure on the other side. I bought Alumiweld. I just received it and I haven't tried it yet. Not sure yet if I can do an overhead application (without having to flip the boat over).
If anyone of you has tried this product please chime in with your experience. Alumiweld at: http://virtual-adnet.com

Doc,

I did not have to replace enough to worry about losing strength but the ones I replaced held up for several years with no leaks. There is no way I would try a whole boat for the reasons you mentioned. Thanks for bringing this up so none of our sniffer group will think this is a major overhaul suggestion, it's not, it's just a way to replace a few to keep the boat dry. Bailing is not my favorite way to fish.

Big Minnow,

I have used the alumiweld for other applications. Don't know if it will work for you but as I recall the material is thick enough that it should stick for an overhead application. Several thin coats are better than a thick one as the thick coat takes a good while to dry thoroughly. Good Luck!
