In brief: No

Watery is generally well absobed.
If you had water toxicity, drank so much water you lowered serum your sodium to a dangerous level, you potentially could have diarrhea but this too would be unusual.

In brief: Generally no

The body has mechanisms to get rid of the excess water, but under certain conditions - if it is taken in very rapidly or in certain disease states, it can cause water intoxication - diluting the blood so that sodium levels can get very low - if low enough, it can cause seizures, coma and death.
Diarrhea rarely occurs, because the water is absorbed in stomach and upper intestine, but it can.
