I just bought an Evinrude 89 4 Hp 2 stroke engine model E4RCEC. It seemed to run Ok in the sellers garage in a barrel of water. When I got home I ran it in a bucket with water up to the cavitation plate, and in a few minutes it seemed to be overheating and died. Smoke was coming from the head unit and the screws that hold the cover on were very hot to the touch. (I had earlier sprayed some WD40 on the starter cord recovery spring mechanism and I am sure some dripped down on the engine parts. This could account for some of the smoke.)
I noticed that the water level in the bucket had dropped a bit, maybe 1/2 ?, below the cavitation plate, and that the water intake was up in the underside of the cavitation plate, so with that tiny drop of water level it must have started running dry for a short while. (other engines that I have seen have the intake on the vertical section of the shaft below the plate so a little dip in the water level is no big deal. My bad this time for not noticing!) It looks like the water outflow port is below the water line , no ?pee tube? up above , so watching for water flow seems very difficult.
So can anyone please help me understand a few things. How do I check for adequate water flow on this engine? And was this short over heating enough to cook it? How can I tell if there is damage? How much will these little guys take?
Also, I am assuming that previous owners of this motor have not properly ran the carb dry before storing so the carb is probably gummed up a bit. Short of dis-assembly and cleaning, is there an effective chemical cleaning strategy?
Thanks
