replacing rivets in a old boat help!!

[txbowhunter08]

in the process of re doing a older duracraft. I got all the old rivets that need replacing out. They are 3/16th solid rivets. I tried using 3/16 pop rivets but there to small. I cant find anything bigger any suggestions? and should I use solid or will pop rivets work?

use a stainless bolt with a lock nut and washer. Silicone both ends before tightening bolt down. Make sure to get the silicone in the hole.

I you don't ever want it to leak, go back with a solid rivet. A pop rivet will leak in the center where the pull pin goes through it, and a nut/washer will leak also.

Air driven rivet gun and bucking bar is the way to get it compressed enough to never leak again.

Hammer rivets. You can get them at most real hardware stores.

stainless and aluminum will oxidize, especially when salt is present. The metal with the lower oxidation potential will corrode, in this case the aluminum. I did the same thing on my jon boat though..... although contradicting what I said it will eventually turn to white powder where the threads meet the hull

Use solid rivets and 3M's 5200 marine adhesive sealant. Wayyyyy better than silicone. Pop-rivets would be like blasting the hull with bird shot...

why not flip it over and take it to a welder and have'em tig or mig the holes up ?

Because a lot of welding shops don't prefer to weld on alum boats. Corrosion, dirty aluminum, awkward positioning and more expensive.

Find you a TBHr with a tigger, case of adult beverage and it's done. Sorry I don't have one, only a MIG.

A mig would do it if you had it set right.
