I've got a 25 four stroke with a tiny bend in the prop shaft. It's so small you can barely see it when you look at it from behind and spin the prop. No vibration that I can tell. How much of a bent prop shaft can you get away with? The lower unit oil was a little milky when I changed it.

You can't get away with any bend in the prop shaft. The out of round rotation of the shaft will keep the shaft seal from keeping the water out. If you don't want to be doing even more serious repairs soon, I'd get it replaced as soon as you can.

Kinda' like being slightly pregnant........
A slightly bent prop shaft is a bent prop shaft. Replace it. It can do more damage down the road.
