At this point, I would go ahead with Mumbles’ drilling advice. Yes, there may be some other issue in that midsection, but the collective knowledge base here can’t come up with it. I personally feel that a midsection with the longer divider between the exhaust and shift cavity would solve the problem as well, but it would have to be from a 58 model only. And, I’m sure you don’t have one "laying around", and if you did, it would probably have the shallow wall as well. Art’s theory about exhaust leaking around the sloppy shift lever makes some sense also, but I don’t know how you could easily "rebush" that shift rod hole.
So, go ahead and drill into that passage. Worst case scenario: you have to pull the powerhead and seal up the hole with marine tex/epoxy. No big deal. Again, angle the 1/16" hole downward into the shift linkage cavity.
