ilike the tile says i was going along and the motor died on me and i got some annoying buzzing from the dash, and i figured it had overheated. i got home and put it in a drum of water and lo and behold no water flow. well my main question here is since this thing got hot enough to melt engine paint and the plate on the head that says "force" on it, what are the chances that i didnt do any internal damage? i ordered an impeller for it and while im waitingit will give me a chance to tear it down. if someone could let me know what to look for i'd really appreciate it.
