I bought a used classic about 3-4 weeks ago and when the seller demo'd the motor in a tank it started fine and had a good water stream. It did smoke quite a bit at first and he said his mix was a bit rich. I have had a 4 stroke for a while now and always heard you guys call them 2 smokes so I didn't think anything of it. I finally had a chance to start the motor this weekend in a tank and it smoked from the lower unit and I noticed no water stream. I shut it down right away. Residual smoke kept coming out of the lower unit and a bit of black residue from the prop. I drained the lower unit oil to replace it and it was a good color. I am assuming I need a new water pump. Can anyone tell me what else I might check and if the smoke from the lower unit can be a sign of something major?
Thanks
