Anyone else having trouble with the welds on the pontoons cracking? Let me explain a little first, I work at a rental site for the militay and all boats are trailered by the customers, we have 2 2013 models and 2 2012 models,(both 2086) along with some 2008 model years. The 2012/2013 models are cracking on the rear welds causing the pontoons to take on water. We also had the front of the pontoons start leaking at the front where the bottom of the first section meets up with the "V" ridge on the bottom of the pontoons. We thought this might be caused by customers beaching the pontoons or hitting the dock/ramps to hard but none of our other pontoons or boats show any signs of this. Any ideas or suggections?
