Picked up a 1999 Alumacraft Lunker 165 dirt cheap but I knew the boat leaked as the previous owner had tried to spray the leaking area with a rubberized coating. Evidently this was an ongoing problem for the company for several years according to the internet but I've bucked and replaced brazier rivets before and have the proper rivet set bits, air hammer, etc. I got the front deck off and the area of most concern has no foam so it can be easily inspected. I can't see any damage but the rivet backs appear slightly elongated as opposed to the proper "biscuit" look. Also the gap at the bottom nose of the boat where the sides come together has about an inch of sealant missing. Surely this was a mistake but I can't believe it hasn't always leaked???? Was thinking of bucking or replacing some of the rivets then use Gluvit and 3M 5200 sealant. My question is do the rivets and sealing job look normal and if any Alumacraft fans heard about these problems? I've heard one say it's a sealant issue.
