I was riding earlier and hit a deep hole and got stuck while i was winching out it stalled while the exhasut was under i towed it home and im not sure if i should try to start it or not i drained the oil it did have water in it

 

Check the air box and filter for water entry,if still in doubt pull the spark plug and crank it over.If no water shoots out and you have spark,just new oil and filter since you've already drained it.
