Stamped Aluminum Gas Tank Repair

[CARY PALMER]

I HAVE A 1965 JOHNSON 3 HP THAT NEEDS SOME TLC FOR THE GAS TANK.  THERE ARE NUMEROUS SMALL SCRATCHES AND DENTS IN THE ALUMINUM SUCH THAT I’M CONCERNED THAT STANDARD BODY PUTTY WON’T HOLD WELL.  ANY SUGGESTIONS?

try Ebay for a better tank. short of that I use J-B weld for the bigger dents then prime and use filler.

I am not positive how many years they used that same tank, BUT, in 1947 I believe they used a 2 piece cast tank. They NEVER dented.

It was only one year they used the cast tank. Someone correct me if the tank was changed. The ’47 was a 2.5 hp but I do not think they changed the tank for the 3 hp.

I have used  body filler with success…just prep the surface   sand  and  wipe of with carb cleaner …  overfill the dent  a bit and sand down to shape..

 

JB works good to    I actually  used it  to repair  my 75hp skeg instead of paying a shop 300$+.    Good enough  for my pride

Given my lack of skill and patience ….I’ve always said that that’s the sort of motor I would choose for a restoration project;  one of those with cast tanks and cowlings.  Makes it a lot easier!

Actually, my tank doesn’t look so bad compared to those I see on e-bay.  Went to town and bought some JB Weld and will start the process of filling in the small dents and scratches  My thanks to all for your feedback.  Doesn’t take much to ding this thin material.
