Just checking to make sure about something. I have an Evinrude with the exhaust behind the prop. While running it in a 55 gal barrel I noticed when I took it out of the barrel a white oil and water gunk inside the exhaust, behind the prop and inside the case. I want to make sure this is normal. I understand that if I had it in the river and moving this might not happen. But being in the barrel it's possible it's airiating and causing this. Please give me a few words of wisdom.
