matching up lower unit

[gsb]

Hi y'all,
I have a 92 2 stroke c115 and am wondering how to figure out which years and sizes of lower units will fit it. I have a huge crack working from the back toward the gear casing that i figure will kill it someday. I want to start looking around now to adopt a replacement.


Thanks,
Scott

1984-1992 have the same lower unit.

you can have it welded if it isnt into too bad....if you DONT do it soon, the corrosion will crack it faster.
