Re: lifespan of an inflatable
I bought a used 1986 Zodiac MKII 14 footer a few years ago. There are plastic cones at the pontoon ends that are glued on. I had my first air leak around the cones the end of last year, and was able to re-glue them and the seam by myself. (Zodiac Dealer wanted $500, glue was about $45.) My boat is made of PVC, and so far has held up to Minnesota summers and winters. I was told by Zodiac that the best way to store them is inflated and out of the sun. Not folded up. I was also told that storing a boat folded up is the worst way. If you buy an older boat have the seller inflate it and spray all the seams with Dawn dish soap mixed with water in a spray bottle before you buy it. The leaks, even small ones, will bubble up and be exposed. Put some water in the bottom on a dry drive way and see if any leaks out of the floor seams. I was told that I should watch my transom because as the glued surfaces grow old, the wood transom may separate from the boat. So far, not a problem. I run a 15 HP on mine, it's rated for 55 HP. If you find leaks in the seams be ready to glue if you buy, or it may cost alot to repair.
