Has anyone ever had this happen to the spark plug in your outboard. It came from a 2015 ProXS Optimax 250 with about 300 hours on it. I just had it serviced about 50 hours ago.

It was the #3 cylinder, I plan on taking it in this weekend. They were not gapped correctly when I pulled them all, they were at .032 and should have been between .042 - .044I have seen this before, is it the number 6 cylinder ? However do not run that motor any more until you do a compression test or take it to a dealer.
I did not know that, I will definately have to keep that in mindRonc4773... X2.
The exhaust bypass on the engine needs to be out of the water at idle so it can breathe or any Optimax will foul plugs all day long. Trim it up sitting moving at idle until the bypass is out of the water... then trim down to take off...
I think it's called the exhaust bypass...
Actually I was wrong, I thought it was cylinder # 3 but it was # 6 with no compression. Luckily Mercury is going to cover the cost to fix it. Still not sure what caused it.I have seen this before, is it the number 6 cylinder ? However do not run that motor any more until you do a compression test or take it to a dealer.

Is this only on 2 strokes or is 4 stroke able to have this problem? I had one time when I got the boat, I left the motor all the way down and started it and some smoke came out of exhaust and sounded different. that was the only time I seen smoke like that.
