Odd that once you cooled it down via auxiliary pump it stayed that way on it's normal feed.
Well, I have to believe that something was clogging the intake (sand or seaweed). I must have flushed it out or the obstruction came out of the intake thru hull. No, the idling wouldn't be a big deal. the engine stays plenty cool at idle. It most certainly had something to do with getting stuck.
