What's the best way to repair a blow up port on a rubber raft? Heavy duty raft the air port section fell out?

Question

There is a 2.5" hole made in the material, and the blow up section with the air valve has a rubber flange and was glued into the material. I don't know if I should clean it and use rubber cement, or what would work better. Some good info on this from someone who knows how to do a durable repair would be very helpful. No speculation or guesses because if it comes out in the middle of the lake with a motor on the raft it will be a real problem, possibly life threatening to my children, so if you don't know don't act like you do for the points as so many do here. Thanks in advance.

Answer 1

Locally, we have a couple places that do inflatable boat repairs.  I have done several repairs on my Avon, using only Avon repair kit.  This was our dinghy that we used extensively.

However, I would take any repairs to the valves or the valve ports only to a professional.  You are correct in the vital nature of this repair.  If it is an Avon, make sure they do in fact have a track record in Avon repairs, same with any other manufacture.
