It is apparent that water intruded into the ignition system and most likely the primary which means to remove the distributor cap and check for any signs of moisture. you may have to blow it out really well if you hace access to shop air or compressed air. Start with that and let me know what you found....Also check all the connectors going into the distributor and coil.

then it is not sparking the spark plugs at the right time

sounds like it is out of time....when you guys replaced the distributor how did you make sure you put the distributor back in the exact same position it came out?

or you have some plug wires crossed up on the distributor cap itself...check that first
