Motor died on me in the middle of the marsh and will turn over but immediately die. I checked the oil and noticed it was leaking a little from the oil line and also had gas in the oil. It's a Kohler engine. I did poor a bottle of sea foam in the gas tank right before the hunt and it ran fine to the hole. Thoughts on what it could be besides a carb issue?

Did you you follow the instructions on the seafoam? Did you put the correct ratio?

To the best of my memory, yes but it's possible i put a little much in.
