I don't thing my 45 horse merc is cooling properly, but I don't know much about how it is supposed to work. The impellor looks fine. Water comes out the pee/exhause hole near the top back of the motor, but it just spits out water, is that all it is supposed to do? It is almost a real heavy drip, it doesn't shoot out or anything like that. Another thing, the water that does come out is kinda hot. I mean, you can touch it, but you wouldn't want to hold your hand there too long. Also you cannot keep your hand on the enging block for more than two seconds because it is hot. I dont think this is normal, but I just want to make sure. Does this old of a motor have a thermostat? Could the water tube be clogged? How do I fix this?
