Thanks Huey, I really appeciate the advice. Greg C

Thanks for the replies It is a 2000 Model Johnson 175HP, 2 stroke outboard. As soon as it started blowing smoke I took it back to the mooring. It wouldn't have been running for longer than 5 minutes. Didnt seem to lose power just blew a lot of smoke and I mean a lot of smoke. I'm getting the tank drained tomorrow so will see how it goes with some fresh fuel and then I'll get it checked out.

Hi all, I filled up 2 weeks ago with 70 litres of contaminated fuel. It was suppose to be premium unleaded, but what I actually got was a combination of unleaded petrol and diesel. The outboard motor was blowing a lot of smoke and I'm going to drain the fuel tank. The question I'm hoping someone can answer is… what affect would it have on the engine in terms of damage? I have received mixed reports from 2 different mechanics. One mechanic is telling me it would have no affect as diesel is a lighter fuel with more oil and as a result it will just blow more smoke. The other mechanic is telling me to conduct a complete check on the engine. Any thoughts let me know?
