Re visiting this topic, couldn’t find anyone to replace flu, three places looked at it, said they would sort it, but then refused after keeping me wait around, Nantwich I was waiting three weeks, and eventually just said he wasn’t going to do job. Overwater, work shop ,wouldn’t commit and messed me around for two weeks, made promises but let me down. So I got a steel band, wrapped it around rusted outer skin( inner skin was intact) then attached two jubilee clips above and below, put heat resistant silicon, over the hole first, and over the out side top and bottom. Painted it black heat resistant paint, and now got it burning away, just keeping an eye on it now. Will try and put b4 and after pic up. Cost me £100. The Morso flu kit I was going to get was about £650, and if I had used those marinas would of been a few ton on top of that, so fingers crossed it works.
