Iám not so good in english but I will try anyway to describe my prolem because I need help. I will repair my bottom because I had a leak there. But before I plastic I would to check my keelbolt and se if they are damaged.But how do i find them and how many are they.The red streck in picture is the area over the keel and the bolt must be incast there. But i don´t want to take away all that.Perhaps there is someone who has some experiense.
