Hey guys, about a week ago I asked wich way to install the water pump impeller on my 25r73a Johnson and kfa4303 sent me a great diagraghm and it seems to pump more water than before. But when I put my hand to the exaust I can bearly keep it there maybe 10 secs. The motor has never run hot, and always performed great. Is the exaust supposed to be that hot? Could it be because of the extra water pressure from the new empeller?
