It has no water coming out at all. The thermostate hose blew a hole in it and it got hot. It runs good, it just has no water coming out of the pee hole at all and I am worried that I will burn it up so I won't run it until I address this problem. I pulled the lower unit and installed a new water pump and it is on the tubes going to the thermostat. One of the tubes seems to be loose at the top. Is there a grommet on it. I looked at a breakdown of the exhaust housing and all I see is a gasket that if it were blown it would put exhaust into the cooling system tubes and through the power heads and out the pee hole. Is there a diaphram or something in the power head that could do this as well? Any suggestions where to start? Any help would be greatly appriciated. thanks for reading.
