I wanted to clean out the carburetter of my 8 hp outboard. The mechanic advised strong Seafoam mix, so I used 1 gallon of gas with 16 ounces of Seafoam. But I forgot to put any two cycle or oil in the gas.
The motor started well, and idled smoother and smoother as time went on for about 10 minutes. I slowly revved it up & down. Shortly after that it just died.
After about two minutes, it started again and ran for about three minutes and then died. Only 1/16 of an inch of gas left in the tank, so I figured it was out of fuel. (But that's OK because I just wanted to get that seafoam in the carburetter). I let it sit.
Anyway, after it died, I noticed smoke coming from the top of the motor, and it was very hot. Do you think any damage was done?
