Gray smoke pours out of the back, engine running very rough, kill switch doesn't shut the engine off now.
- New spark plugs
- Compression 122-125 across the three cylinders
- New gas
- Oil change
- Run well previous weekend, till I put potentially bad gas in it

I just bought the ski a few months ago (71 hrs) it was running fine 70mph 8000 rpm. This past weekend I was forced to put some gas in it from a small marina. Within a few minutes it start hesitating over 5000 rpm, I took it off the water shortly after and drained most of the gas (3 gallons left) filled it up (12 gallons) replaced the spark plugs and changed the oil and filter (Sea-Doo XPS 4 Stroke Synthetic Blend Engine Oil - Gallon 293600122) since the Sea-Doo mineral oil appears to be superseded with the synthetic, filled it up to the top of the curve on the dip stick (about 3 1/2 quarts.) Now I can barely keep it running and gray smoke pours out the back. I took 10 oz of oil back out and it is reading 1/2 between the curves on the dip stick. I'm not sure where to even start.
