Scott only a retarded retired marine would come up with that.. Besides it's my Johnson and my Pee hole and I can say anything I want. They wont cover anything with an impeller they will just say you ran aground and picked up sand and ruined the impeller. I would still bet HIS pee hole:doh is fouled. If the engine has a overheat buzzer on it fire it up in the yard and run it if it doesn't go off then it's most likely what I say..
