About how much water? A table spoon or less? Was the oil/lube milky color?
I doubt you have any cracks or damage. As long as there is/was non watered down lube you should be fine. Typically at 3% water the lube to begins to not be able to lubricate. The lubes other job beside lubrication is to absorb moisture. Main reason why to change it.
Typical leak points would be your top/bottom plug seals/o rings.
Next I'd look behind your prop and make sure no line has cut your shaft seals.
Next would be at/around your waterpump. Which can be fixed by just replacing with a full water pump kit/o rings etc.
Depending on how long your engine sat and the temp swings, you could just have/had some moisture from cold/warm air. And no real problem.
