Extra Gas Filler Hole

[slim60]

I soldered some pinholes on the bottom of a 22 Evinrude gas tank then tried to fix what looked like a patch on the top. This time the hole just got bigger so I took it off. I wondered why the filler was on the back instead of the front. Anyone seen this before, and why was it done? Would it be easier to use gas tank sealer to re-apply the patch? The model/serial numbers were cut out too.

Good Morning Slim60,
The tank style you have was not used in 1922, that tank style would have been used in 1927-28 period.
The tank cap filler neck should be and originally was in the hole towards the front of the tank. However I can see the benefit for someone wanting to relocate
It to the rear of the tank. If a motor has the accessory tilt bracket it would be best if the cap & filler neck were towards the rear of the tank. As a motor in the tilted position would pour gas out of the vent hole into the boat. Something that Evinrude possibly should have taken into consideration.
It is always interesting seeing the modifications made to motors over the years.

So that possibly explains why the vent was soldered
shut and this hole was punched in the rear of this tank.
Slim60 does the motor your working on have the
accessory tilt bracket. If not possibly the motor that
tank originally came from did. Mysteries we may never
be able to answer but we can speculate.

The motor will tilt only after the two screws are loose on the transom angel adjustment. Now Tubs, should I try to re-solder the patch or can I use gas tank sealer? I plan to paint. I used Map gas, flux, and 50/50 solder to fix the leaks. I’m experienced with copper but this steel is new to me. I could watch your video again. Thanks, Slim

I’d put a patch on it.
Use your copper skills getting everything clean first.
I’d make every effort to get the tank sealed with solder
before using a sealer. I found that once I got the knack
soldering was not difficult. If you have a spot that leaks,
checking with air, it probably has some dirt in it. Just
blow the solder out in that area and add just a touch of
flux and try again. I just use propane. Seemed to be hot
enough.

Thanks Brooke and Tubs. I can see why this was done now as I need to tip my motor when going under a bridge up north. I’ll get more acetone and try again.
