I have an aluminum bass tracker that sprung a serious leak this morning on KY lake (took on 20 gallons in 3 hours). I found a rivet that holds the center flute pouring water from it when I loaded the boat on the trailer. It also leaked all the way home from KY lake (200 miles). Can I remove the rivet and pack the hole with silicon or do I have to put a new rivet in there ? Have also considered epoxy used to fix holes in aluminum boats. Any suggestions would be greatly appreciated.
