I'm new here so I apologize if I screw something up but I'm hoping someone can point me in the right direction. My family and I own a 52' houseboat that we keep at Bullfrog Marina in Lake Powell. Yesterday we received a call from the marina saying that the houseboat was sinking, luckily one of the owners was able to get out there and get it out of the water before it became a catastrophe but now we have a boat that doesn't float. We have steel pontoons on the boat and they were full of water. Offshore Marina will weld the holes and do what they can to repair the pontoons so they work for the remainder of the season (two more trips to go yet) but we are thinking it is time to find some new pontoons. The boat is at least 25 years old and while we maintain it as best as we can it seems that there are multiple holes in the pontoons and that makes me think they are preparing to fail completely. Looking on line I have not been able to find any used steel pontoons for sale but I am sure there must be boat parts out there somewhere. Having new ones fabricated is most likely out of our budget right now. Do any of you have an idea of where I might find used pontoons that we could look at to see if they are in better condition than ours currently are? Thanks for any help and advice!
