Snow Blowers

Hi I have a snowblower I bought one year ago. It got flooded last week so pulled the plug and rolled it over a few times. While pulling the plug it felt like it came out tough, didn't think too much of it. When I went to put the plug back in I spun it in about three turns by hand and then about one turn with a socket and then it went cross thread. The threads are pulled in the middle, just curious if I can do anything to get a warranty to fix or replace head?
