Hi:
I just purchased a sailboat that came with a small inflatable dinghy and a 4 HP Johnson Seahorse outboard. (don't know the year). The motor seems rot run fine (smoked just a little) but after running a few minutes I looked at the oil bottle that was in the boat... It was 4 cycle 10W40 engine oil!!!
I asked the previous owner and he confirmed that he accidentally used that in the most recent gas mixture. I am not sure how long the motor ran with this mixture but it may only have been 30 minutes or so in short (5-10 min) trips from the dinghy dock to the sailboat.
I drained the gas, and filled the tank with 93 Octane gas and a 40:1 mixture of Starbright 2-cycle oil. I also added just a little SeaFoam for good measure.
The question is: What sort of damage could have been done by running on a 10W40 mixture?
The motor seems to run fine now but what should I be aware of?
Thanks
