I lit my tracker warranty on fire, and glad I did. Welding aluminum is not brain surgery, and most area's have a skilled and reputable shop around that can handle it. I had a crack develop on the underside of my hull 3-4 years ago............I don't know what caused it...Stress?? Hitting something?? Etc IDK??? I am betting I hit something as the aluminum looked "creased" along the crack....I called Tracker, they told me strip everything off it, drive it the 100 miles to the dealer, drop it off, wait for 6-8 + weeks while they sent it back to the factory for repair, and they would call me when it was ready. I said "you do know it's fishing season right? Will I have a boat to use in this time??" . They said NO. I said to hell with your warranty, I took it to a local repair shop 10 miles away. They did the job while I waited, dropped it in the water on the way home, and it's been fine ever since. If it ever cracks again, I will take it to the local shop again, they told me there is nothing they couldn't fix on the boat, I might have to pull a floor up or something on my end to make it easier for them to get to, but still, I can get that done a heck of a lot quicker, and be back on the water ASAP by going with the locals, as they do a great job, and only charge $70, than by using Trackers worthless warranty.
