Hello all. First time post long time antique outboard fan and member. I recently acquired this old outboard. When I got it (fall carlisle) it was covered in grease and dirt. After giving it a good cleaning I see the gas tank which appears to be original says evinrude not elto pal. I have never seen that before . Any insight i would much appreciate i would like to keep the engine as original as possible get it blowing some blue smoke again!
