my 150 has a overheat problem temperature at head 180 f. with laser. I have replaced the entire impeller unit, replaced the temperature sensor. tested for bad gauge. Just took out the two thermostats (what a job that was, frozen). Tried to flush with the open orifices. No water came out. Is there a blockage??. the lower unit had water coming out. I have not installed the new thermostats until I see water coming through the head. I heard there is a back flush procedure, how do you do it? WHAT IS WRONG. HELP!
