Hello all you experts out there!<br /><br />Last weekend my 1990 Johnson 120's overheating alarm sounded and the tell tail was only trickling so I immediatally shut the engine down. After a long cooling down period I restarted and it was pumping so-so but not to my satifaction. But, I made it home with no alarm or damage. Last evening I tore down the water pump which only had 10-20 hours on it and everything looked good as new. Also blew the system out with a hose. When tested with ears muffs I got a good pissa stream. Now the mystery! Ocassionally on the muffs, the tell tale would really blast for a few moments then back off to the so-so stream. Could this be a funky thermostat? Could I have sucked sand into the head?<br /><br />Any comments and help to be in-water by saturday would be most appreciated seeing until last week it rained here (in Mass) for 40 days and 40 nights! <br /><br />Until recently, I was a Merc man and know it has a much different cooling system than OMC. In fact, if I could'nt pressure wash my driveway with the pissa I knew something was wrong........ <br /><br />Thanks!
