hey guys, i replaced my whole water pump in my 1988 28hp johnson about 2 months ago.....i ran it in a barrel it worked great....i wanted to have it ready for summer, so after that i replaced the thermostat...after replacing the thermostat i ran it again...the water cover leaked....iafter that i pulled the cover adjusted the gasket added some shellac, put it back together...ran it a few days later to see if it leaked....and good to go..pumping water, no leaks.....so i put it in the garage.....now! 2 months later i put it on my boat and throw a bucket under it....start it up...no water...shut it off and start it a few more times, nothing!...so now the motors hot and so am i...pull the lower unit and my impeller is toast...a million pieces...and the metal housing is slightly melted into the plastic one.......OK what the hell did i do wrong....i never started it out of water...ever....these pumps aren t free..and i dont wanna mess it up again, can you over torque the housing bolts, because thats my only idea??? as always thanks for thoughts....heres a video of after i did the pump, right b4 i put it in the garage....notice the water coming out of the hole in the front of the mid section...i thought it was strange..and didnt notice it before the new pump....u can also see that im not crazy and it was working http://youtu.be/ekcpd7bGE6Y
