Quinte Fishing

Looking for a little advice on repairing a slight leak in my aluminum boat. I have a couple rivets in a cross beam in my 10 year old Discovery Aluminimum that seem to have loosened just slightly. The beam is around the middle of the boat. In rough water when the bottom of the boat moves up and down against the water, I'm taking in a trickle of water coming out from under the cross beam. Am I better off putting a coating of marine silicone around the outside of the rivets in question, or try and seal the beam inside?? Any help would be much appreciated. Want to try and get this fixed up before our week at camp. Tight lines

Hi weedman
A couple of things come to mind. I think you can access the floor of the boat[inside]. If you place a hard object outside beneath the offending rivet you can strike the rivet from the inside to form a better seal. try this first before the sealant.
As a second thing some guys get there boats welded when they have a problem like this....Larry
