Yep, me too.. My boat leaked just enough to be annoying, and I got sooo sick of fixing differing leaks.. Here is what I finally figured out. (Hey so you have been doing this for years, so what maybe it will help some other broke d_ck like myself) I pushed a section of 1/2 inch pvc through the drainplug with the "bell" on the lake side of the transom.. I cut the pvc just inside the hull with just enough meat to glue a pvc ball valve in place, then I siliconed the crap out of the assembly. The boat leaks.. And so what, I get on plane to go to the next spot.. Reach down and open the valve, all the water siphons out.. And I mean quick too.. With no drain on my batt like a bilge would do.. Then just close it up before coming off plane. What is really cool is if it gets windy enough to push the boat around a little too much you can flood the hull a little to add a quick 500 or so pounds to fight the wind.. Really helps in a little Jon boat. It has given me a little more time on this old beaten hull, and will allow me to get another riveted boat (rather than spending big$ on an all welded boat) once I replace this one eventually with no concerns about a little leakage.

Another way to fix the problem of a leaky boat. Cover the rivets or entire bottom of the boat with fiberglass.Relatively cheap fix.

we have to jb weld the bottom of our boat about every year and a half to 2 years. Kind of annoying, but not really that bad of a deal.

JB Weld and duct tape. Where would we be without 'em?

Get a buddy to help with this. Have him/her put a hammer on one side of the rivet for backing and from the other side pound the rivets back down with another hammer. Just move to each rivet until your done It's time consuming but I did it to a 50yr old jon boat and not one rivet leaks now.

At the bottom of the lake.

Ding ding ding!! Winner!!!

Done all of the above, none of them fix the over-all problem of the over-all crappy design of the poor man's riveted boat.. No more trying to shine a turd.. Let her leak and drain every second or third time I get on plane to move to the next spot!
