Is there a warranty on this item? We ordered in May of 2018 used the boat until Oct 2018, winterized (full of antifreeze) and stored in heated garage no hard freeze. We just went to start the boat for the summertime and it leaks like crazy at the seam. This is the 3rd one, our 1st one lasted almost 8 years and the last 2 just over 1 year each. Not sure if we should bother ordering a 4th?
