Hi guys, I have a 25hp yamaha I do not know what year it is, but this is what the motor plate has: E25F 648 S the motor was working fine and the last time I used started leaking a cream looking oil from the exhust (water and oil). I check the lower unit and is fine, the oil is coming down from the upper section (motor) does any has an idea what do I need to do to fix this problem, I will apreciate the help

fix the rich fuel problem what your seeing is unburned fuel/oil mixed with water can be caused by a bad plug or a sticking needle in the carb or any other ign or fuel delivery problem. something is not allowing complete combustion of the avalible fuel oil mix. can also be caused by a bad fuel pump diaphram.
