need help with 76 evinrude leaking gear oil

[tbsteverson]

Have a 76 evinrude that is leaking gear oil. It is leaking out of a little pressed in plug on the opposite side of the oil drain screws. It started the 3rd time I ran it after rebuilt the foot on it. I'm just wondering if it would hurt to weld it up or if I can try taping it and pull it out then trying to find another plug thing. But any solutions I would appreciate it allot trying to go fishing wile our little river has some water in it lol.
