I just replaced the impeller and I'm not getting any water out of the exhaust stern hole. As far as I can tell, all the connections were made correctly, there doesn't seem to me any obstructions (we blew air through when we had the lower unit off and pulled the thermostat off as well). Is there supposed to be a gasket for the water pump housing? The schematic only shows a stainless plate and the aluminum water pump housing itself. Is that machine fit or should there be a liquid gasket of some sort? The two tubes appeared to be fitted well when we put the lower unit up and connected back up. It flowed for about a minute, but then it stopped and the head got hot. Any suggestions? There was no water when we checked the spark plugs.
