I have a decent crack in the bottom of my tracker. Someone before me had put some rubbery stuff around it, and it held for a few years, but it has started to come off and put more water in the boat. What can I put on the crack to stop it from leaking?

Definitely have it welded ... If a chunk came out, your Boat could sink faster than you could get it out of the water ...
Weld it, definitely weld it!

TIG welding is the only permanent solution. Do not have each crack welded. Have a good welder scab each side with a single piece of aluminum. Fixed properly it will last a lifetime.
