Just bought a used 2003 Yamaha 4 stroke 30 jet that the owner says has less then 5 hours on it, and it sure looks brand new. <br />Here is the issue, we took it for a short test run and it ran perfect, I paid for it and brought it home, well the first thing I did was pulled the dip stick to check the oil and oil pour out of the dip stick hole. The guy over filled the oil a bunch!!! I drained the oil to the proper level, checked for signs of leaks and pulled the plugs. The oil was still sort of clear, there was no signs of oil being sprayed and the plugs looked fine. I called the guy and he assured me that he had just put the oil in and had not ran the motor much. <br />Since everything looks good and there is no signs of damage, should I be concerned? What other signs should I look for to determine problems that this may of caused? The guy will refund my money but I really want this motor and got a super buy on it and would like to keep it.
