About a month ago while trying to load my boat up in a very swift current and wind (tropical storm lee was coming), I ran over some sort of debris with my motor. After getting about halfway on the trailer I killed it for some reason and then tried to start it again. It would turn over but not start. I thought I had damaged something, but when I got it home after winching it the rest of the way on the trailer, it started right up and I could not see any damage. The problem has not repeated itself and I have explored everything I did in my mind and can find no answer. Probably should not worry but I go out to rigs fishing and do not want to get stranded. Any ideas?
