Aluminum boat repair

[cfdkulax]

Hello All,

I am looking for some advice on how to repair my aluminum row boat.  I discovered some cracks and questionable rivets.  Thanks in advance.

Get a yellow MOP torch and aluminum brazing rods. Heat the boat and touch the rods melts like solder

scuff it up with sand paper and flex seal it

Watch the heat around sealed seams, you can melt it out with to much

I tried the MAP gas and the aluminum rods,it looked pretty easy, I had 3 holes from an old transducer.Every Time I got one hole filled it would fall out from heating the aluminum to do one of the other holes. Ended up using J-B waterweld Worked great!

Drill the rivets out with a 1/4" bit.  Get some 1/4-20x1 machine screws, nuts, wahsers and marine tex them in the holes. Cut off the excess at the nut. I have more than 200 in my duck boat. The marine tex will seal in, around and between the washers and to keep water out  act like lock-tite on the threads. They will never leak or come loose.

There is no way any Brazing can be done,  for many Reasons.

The Areas have to be Brushed and all Oxidation Naturalized & Removed 

The Cracks need to be drilled at each end to prevent spreading in this case 1/8 drill will do 

Rivets Need to be backuped with dolly one side Peened over  from outside to tighten them.  

Remove all Moisture Mix Epoxy Apply& build up in & outside, 

Remider Nothing will work unless all the Oxidation is Removed.
