I have recently purchased a 12ft avon inflatable and on closer inspection it seems the transom has had a problem with water intake. I think that who ever repaired it before was far from a speciaist and they have botched it, so I have taken the old one out and I am going to replace it. Can anyone tell me what type of glue I should use?. I have got some two part hypalon glue, would this be okay? If anyone can give any prepping tips this would be most appreciated. Many thanks Murphoir......
