I have an older 20 hp Merc that is in good condition and it has ran just fine all year. The last couple times I have had it on the water it has been smoking a little bit. I don't know jack about motors so maybe someone can help me. There is water circulating through so I assume the water pump is ok. Its not a cloud of smoke, but more like a steam....I guess. The portion of the lower unit that is out of the water feels pretty warm but not extremely hot to touch. Is this normal? The last two times I have been out, the air temp has been really cool. Would this have anything to do with the smoking? The motor still runs fine, I just don't want to blow it up. Thanks for any help.
